| The type of switch to be used by all networks in given cluster. | |
| ||
| ||
| ||
| The compatibility version of the cluster. | |
|
7.28.1. custom_scheduling_policy_properties
Custom scheduling policy properties of the cluster. These optional properties override the properties of the scheduling policy specified by the scheduling_policy
link, and apply only for this specific cluster.
For example, to update the custom properties of the cluster, send a request:
PUT /ovirt-engine/api/clusters/123
With a request body:
<cluster> <custom_scheduling_policy_properties> <property> <name>HighUtilization</name> <value>70</value> </property> </custom_scheduling_policy_properties> </cluster>
Update operations using the custom_scheduling_policy_properties
attribute will not update the the properties of the scheduling policy specified by the scheduling_policy
link, they will only be reflected on this specific cluster.
7.28.2. fencing_policy
A custom fencing policy can be defined for a cluster.
For example:
PUT /ovirt-engine/api/cluster/123
With request body like this:
<cluster> <fencing_policy> <enabled>true</enabled> <skip_if_sd_active> <enabled>false</enabled> </skip_if_sd_active> <skip_if_connectivity_broken> <enabled>false</enabled> <threshold>50</threshold> </skip_if_connectivity_broken> </fencing_policy> </cluster>
7.28.3. firewall_type
The type of firewall to be used on hosts in this cluster.
Up to version 4.1, it was always iptables
. Since version 4.2, you can choose between iptables
and firewalld
. For clusters with a compatibility version of 4.2 and higher, the default firewall type is firewalld
.
7.28.4. gluster_tuned_profile
The name of the tuned profile to set on all the hosts in the cluster. This is not mandatory and relevant only for clusters with Gluster service.
7.28.5. required_rng_sources
Set of random number generator (RNG) sources required from each host in the cluster.
When read, it returns the implicit urandom
(for cluster version 4.1 and higher) or random
(for cluster version 4.0 and lower) plus additional selected RNG sources. When written, the implicit urandom
and random
RNG sources cannot be removed.
Before version 4.1 of the engine, the set of required random number generators was completely controllable by the administrator; any source could be added or removed, including the random
source. But starting with version 4.1, the urandom
and random
sources will always be part of the set, and can’t be removed.
Engine version 4.1 introduces a new RNG source urandom
that replaces random
RNG source in clusters with compatibility version 4.1 or higher.
7.28.6. version
The compatibility version of the cluster.
All hosts in this cluster must support at least this compatibility version.
For example:
GET /ovirt-engine/api/clusters/123
Will respond with:
<cluster> ... <version> <major>4</major> <minor>0</minor> </version> ... </cluster>
To update the compatibility version, use:
PUT /ovirt-engine/api/clusters/123
With a request body like this:
<cluster> <version> <major>4</major> <minor>1</minor> </version> </cluster>
In order to update the cluster compatibility version, all hosts in the cluster must support the new compatibility version.

7.28.7. external_network_providers
A reference to the external network provider available in the cluster.
If the automatic deployment of the external network provider is supported, the networks of the referenced network provider are available on every host in the cluster. External network providers of a cluster can only be set during adding the cluster. This value may be overwritten for individual hosts during adding the host.
7.28.8. scheduling_policy
Reference to the default scheduling policy used by this cluster.
The scheduling policy properties are taken by default from the referenced scheduling policy, but they are overridden by the properties specified in the custom_scheduling_policy_properties
attribute for this cluster.

7.46.1. active
Indicates if the disk is visible to the virtual machine.
When adding a disk attachment to a virtual machine, if the server accepts requests that do not contain this attribute the result is undefined. In some cases the disk will be automatically activated and in other cases it will not. To avoid issues it is strongly recommended to always include the this attribute with the desired value.
7.46.2. actual_size
The actual size of the disk, in bytes.
The actual size is the number of bytes actually used by the disk. It will be smaller than the provisioned size for disks that use the cow
format.
7.46.3. bootable
Indicates if the disk is marked as bootable.
This attribute only makes sense for disks that are actually connected to virtual machines, and in version 4 of the API it has been moved to the DiskAttachment type. It is preserved here only for backwards compatibility, and it will be removed in the future.
7.46.4. initial_size
The initial size of a sparse image disk created on block storage, in bytes.
The initial size is the number of bytes a sparse disk is initially allocated with when created on block storage. The initial size will be smaller than the provisioned size. If not specified the default initial size used by the system will be allocated.

7.46.6. provisioned_size
The virtual size of the disk, in bytes.
This attribute is mandatory when creating a new disk.
7.46.7. qcow_version
The underlying QCOW version of a QCOW volume. The QCOW version specifies to the qemu which qemu version the volume supports. This field can be updated using the update API and will be reported only for QCOW volumes. It is determined by the version of the storage domain that the disk is created on. Storage domains with a version lower than V4 support QCOW2 volumes. V4 storage domains also support QCOW2v3. For more information about features of the different QCOW versions, see here.
7.46.8. read_only
Indicates if the disk is in read-only mode.
Since version 4.0 this attribute is not shown in the API and was moved to DiskAttachment.
Since version 4.1.2 of Red Hat Virtualization Manager this attribute is deprecated, and it will be removed in the future. In order to attach a disk in read only mode use the read_only
attribute of the DiskAttachment type. For example:
POST /ovirt-engine/api/vms/123/diskattachments
<disk_attachment> <read_only>true</read_only> ... </disk_attachment>
7.46.9. shareable
Indicates if the disk can be attached to multiple virtual machines.

7.46.11. wipe_after_delete
Indicates if the disk’s blocks will be read back as zeros after it is deleted:
- On block storage, the disk will be zeroed and only then deleted.
- On file storage, since the file system already guarantees that previously removed blocks are read back as zeros, the disk will be deleted immediately.

7.47.2. logical_name
The logical name of the virtual machine’s disk, as seen from inside the virtual machine.
The logical name of a disk is reported only when the guest agent is installed and running inside the virtual machine.
For example, if the guest operating system is Linux and the disk is connected via a VirtIO interface, the logical name will be reported as /dev/vda
:
<disk_attachment> ... <logical_name>/dev/vda</logical_name> </disk_attachment>
If the guest operating system is Windows, the logical name will be reported as \\.\PHYSICALDRIVE0
.
7.47.3. read_only
Indicates whether the disk is connected to the virtual machine as read only.
When adding a new disk attachment the default value is false
.
<disk_attachment> ... <read_only>true</read_only> </disk_attachment>
7.47.4. uses_scsi_reservation
Defines whether SCSI reservation is enabled for this disk.
Virtual machines with VIRTIO-SCSI passthrough enabled can set persistent SCSI reservations on disks. If they set persistent SCSI reservations, those virtual machines cannot be migrated to a different host because they would lose access to the disk, because SCSI reservations are specific to SCSI initiators, and therefore hosts. This scenario cannot be automatically detected. To avoid migrating these virtual machines, the user can set this attribute to true
, to indicate the virtual machine is using SCSI reservations.

7.112.1. ad_aggregator_id
The ad_aggregator_id
property of a bond or bond slave, for bonds in mode 4. Bond mode 4 is the 802.3ad standard, also called dynamic link aggregation. (See Wikipedia and Presentation for more information). This is only valid for bonds in mode 4, or NICs which are part of a bond. It is not present for bonds in other modes, or NICs which are not part of a bond in mode 4. The ad_aggregator_id
property indicates which of the bond slaves are active. The value of the ad_aggregator_id
of an active slave is the same as the value of the ad_aggregator_id
property of the bond. This parameter is read only. Setting it will have no effect on the bond/NIC. It is retrieved from the /sys/class/net/bondX/bonding/ad_aggregator
file for a bond, and the /sys/class/net/ensX/bonding_slave/ad_aggregator_id
file for a NIC.

7.128.1. cpu
The configuration of the virtual machine CPU.
The socket configuration can be updated without rebooting the virtual machine. The cores and the threads require a reboot.
For example, to change the number of sockets to 4 immediately, and the number of cores and threads to 2 after reboot, send the following request:
PUT /ovirt-engine/api/vms/123
With a request body:
<vm> <cpu> <topology> <sockets>4</sockets> <cores>2</cores> <threads>2</threads> </topology> </cpu> </vm>
7.128.2. custom_compatibility_version
Virtual machine custom compatibility version.
Enables a virtual machine to be customized to its own compatibility version. If custom_compatibility_version
is set, it overrides the cluster’s compatibility version for this particular virtual machine.
The compatibility version of a virtual machine is limited by the data center the virtual machine resides in, and is checked against capabilities of the host the virtual machine is planned to run on.
7.128.3. high_availability
The virtual machine high availability configuration. If set, the virtual machine will be automatically restarted when it unexpectedly goes down.
7.128.4. initialization
Reference to the virtual machine’s initialization configuration.
Since Red Hat Virtualization 4.1.8 this property can be cleared by sending an empty tag.
For example, to clear the initialization
attribute send a request like this:
PUT /ovirt-engine/api/vms/123
With a request body like this:
<vm> <initialization/> </vm>
The response to such a request, and requests with the header All-Content: true
will still contain this attribute.
7.128.5. large_icon
Virtual machine’s large icon. Either set by user or refers to image set according to operating system.
7.128.6. lease
Reference to the storage domain this virtual machine/template lease reside on.
A virtual machine running with a lease requires checking while running that the lease is not taken by another host, preventing another instance of this virtual machine from running on another host. This provides protection against split-brain in highly available virtual machines. A template can also have a storage domain defined for a lease in order to have the virtual machines created from this template to be preconfigured with this storage domain as the location of the leases.
7.128.7. memory
The virtual machine’s memory, in bytes.
For example, to update a virtual machine to contain 1 Gibibyte (GiB) of memory, send the following request:
PUT /ovirt-engine/api/vms/123
With the following request body:
<vm> <memory>1073741824</memory> </vm>
Memory hot plug is supported from Red Hat Virtualization 3.6 onwards. You can use the example above to increase memory while the virtual machine is in state up. The size increment must be dividable by the value of the HotPlugMemoryBlockSizeMb
configuration value (256 MiB by default). If the memory size increment is not dividable by this value, the memory size change is only stored to next run configuration. Each successful memory hot plug operation creates one or two new memory devices.
Memory hot unplug is supported since Red Hat Virtualization 4.2 onwards. Memory hot unplug can only be performed when the virtual machine is in state up. Only previously hot plugged memory devices can be removed by the hot unplug operation. The requested memory decrement is rounded down to match sizes of a combination of previously hot plugged memory devices. The requested memory value is stored to next run configuration without rounding.
Memory in the example is converted to bytes using the following formula:
1 GiB = 230 bytes = 1073741824 bytes.
Red Hat Virtualization Manager internally rounds values down to whole MiBs (1MiB = 220 bytes)
7.128.8. migration_downtime
Maximum time the virtual machine can be non responsive during its live migration to another host in ms.
Set either explicitly for the virtual machine or by engine-config -s DefaultMaximumMigrationDowntime=[value]
7.128.9. origin
The origin of this virtual machine.
Possible values:
-
ovirt
-
rhev
-
vmware
-
xen
-
external
-
hosted_engine
-
managed_hosted_engine
-
kvm
-
physical_machine
-
hyperv
7.128.10. placement_policy
The configuration of the virtual machine’s placement policy.
This configuration can be updated to pin a virtual machine to one or more hosts.
Virtual machines that are pinned to multiple hosts cannot be live migrated, but in the event of a host failure, any virtual machine configured to be highly available is automatically restarted on one of the other hosts to which the virtual machine is pinned.
For example, to pin a virtual machine to two hosts, send the following request:
PUT /api/vms/123
With a request body like this:
<vm> <high_availability> <enabled>true</enabled> <priority>1</priority> </high_availability> <placement_policy> <hosts> <host> <name>Host1</name> </host> <host> <name>Host2</name> </host> </hosts> <affinity>pinned</affinity> </placement_policy> </vm>
7.128.11. small_icon
Virtual machine’s small icon. Either set by user or refers to image set according to operating system.
7.128.12. sso

. The purpose of name
is to simplify the reading of the information element. The name
of a property is exactly the same string which is used in IEEE 802.1AB chapter 8.
Organizationally-specific information elements have the type
of 127
and the attributes oui
and subtype
.
For example, the XML representation of an information element may look like this:

7.157. NetworkAttachment struct
Describes how a host connects to a network.
An XML representation of a network attachment on a host:
<network_attachment href="/ovirt-engine/api/hosts/123/nics/456/networkattachments/789" id="789"> <network href="/ovirt-engine/api/networks/234" id="234"/> <host_nic href="/ovirt-engine/api/hosts/123/nics/123" id="123"/> <in_sync>true</in_sync> <ip_address_assignments> <ip_address_assignment> <assignment_method>static</assignment_method> <ip> <address>192.168.122.39</address> <gateway>192.168.122.1</gateway> <netmask>255.255.255.0</netmask> <version>v4</version> </ip> </ip_address_assignment> </ip_address_assignments> <reported_configurations> <reported_configuration> <name>mtu</name> <expected_value>1500</expected_value> <actual_value>1500</actual_value> <in_sync>true</in_sync> </reported_configuration> <reported_configuration> <name>bridged</name> <expected_value>true</expected_value> <actual_value>true</actual_value> <in_sync>true</in_sync> </reported_configuration> ... </reported_configurations> </network_attachment>
The network element, with either a name
or an id
, is required in order to attach a network to a network interface card (NIC).
For example, to attach a network to a host network interface card, send a request like this:
POST /ovirt-engine/api/hosts/123/nics/456/networkattachments
With a request body like this:
<networkattachment> <network id="234"/> </networkattachment>
To attach a network to a host, send a request like this:
POST /ovirt-engine/api/hosts/123/networkattachments
With a request body like this:
<network_attachment> <network id="234"/> <host_nic id="456"/> </network_attachment>
The ip_address_assignments
and properties
elements are updatable post-creation.
For example, to update a network attachment, send a request like this:
PUT /ovirt-engine/api/hosts/123/nics/456/networkattachments/789
With a request body like this:
<network_attachment> <ip_address_assignments> <ip_address_assignment> <assignment_method>static</assignment_method> <ip> <address>7.1.1.1</address> <gateway>7.1.1.2</gateway> <netmask>255.255.255.0</netmask> <version>v4</version> </ip> </ip_address_assignment> </ip_address_assignments> </network_attachment>
To detach a network from the network interface card send a request like this:
DELETE /ovirt-engine/api/hosts/123/nics/456/networkattachments/789
Changes to network attachment configuration must be explicitly committed.

7.158. NetworkConfiguration struct
7.159. NetworkFilter struct
Network filters filter packets sent to and from the virtual machine’s NIC according to defined rules.
There are several types of network filters supported based on libvirt. For more details about the different network filters see here.
In addition to libvirt’s network filters, there are two additional network filters: The first is called vdsm-no-mac-spoofing
and is composed of no-mac-spoofing
and no-arp-mac-spoofing
. The second is called ovirt-no-filter
and is used when no network filter is to be defined for the virtual machine’s NIC. The ovirt-no-filter
network filter is only used for internal implementation, and does not exist on the NICs.
This is a example of the XML representation:
<network_filter id="00000019-0019-0019-0019-00000000026c"> <name>example-filter</name> <version> <major>4</major> <minor>0</minor> <build>-1</build> <revision>-1</revision> </version> </network_filter>
If any part of the version is not present, it is represented by -1.

7.177.1. auto_sync
Indicates if the networks of this provider are automatically synchronized.
If true
, the networks of this provider are automatically and cyclically synchronized to Red Hat Virtualization in the background. This means that all new networks of this provider are imported, and all discarded networks are removed from all clusters that have this external provider as the default provider. If the name of a network is changed on the provider, the change is synchronized to the network entity in Red Hat Virtualization. Furthermore, if a new cluster that has the provider as the default provider is added, already imported networks are attached to this new cluster during synchronization.
The automatically initiated import triggers the following steps:
- The networks of the external provider will be imported to every data center in the data centers of the clusters that have that external provider as the default provider.
- A vNIC profile will be created for each involved data center and network.
- The networks will be assigned to each cluster that has that external provider as the default provider.
All users are allowed to use the new vNIC Profile.
The default is false
for backwards compatibility.
7.177.2. external_plugin_type
Network plug-in type.
This attribute allows you to choose the correct provider driver on the host when an external NIC is added or modified. If automated installation of the driver is supported (only available for some predefined implementations, for example ovirt-provider-ovn
), this attribute will also allow the system to decide which driver implementation to install on newly added hosts.
7.177.3. plugin_type
Network plug-in type.
Since version 4.2 of the Red Hat Virtualization Manager, this attribute has been deprecated in favour of external_plugin_type
. This attribute is only valid for providers of type open_vswitch
, and will only be returned when the value of the external_plugin_type
attribute value is equal to open_vswitch
.
If both plugin_type
and external_plugin_type
are specified during an update, the value of plugin_type
will be ignored.
For external providers this value will not be shown and will be ignored during update requests.
7.177.4. read_only
Indicates whether the provider is read-only.
A read-only provider does not allow adding, modifying, or deleting of networks or subnets. Port-related operations are allowed, as they are required for the provisioning of virtual NICs.
7.177.5. requires_authentication
Defines whether provider authentication is required or not.
If authentication is required, both username
and password
attributes will be used during authentication.
7.177.6. tenant_name
Defines the tenant name for OpenStack Identity API v2.0.
7.177.7. unmanaged
Indicates whether the provider is unmanaged by Red Hat Virtualization.
If true

This type has been deprecated with the introduction of the OperatingSystemInfo type. Operating systems are available as a top-level collection in the API: operating_systems
The end-user declares the type of the operating system installed in the virtual machine (guest operating system) by selecting one of these values. This declaration enables the system to tune the virtual machine configuration for better user experience. For example, the system chooses devices that are most suitable for the operating system. Note that the system rely on user’s selection and does not verify it by inspecting the actual guest operating system installed.

7.217. RegistrationConfiguration struct
This type describes how an object (virtual machine, template, etc) is registered, and is used for the implementation of disaster recovery solutions.
Each mapping contained in this type can be used to map objects in the original system to corresponding objects in the system where the virtual machine or template is being registered. For example, there could be a primary setup with a virtual machine configured on cluster A, and an active secondary setup with cluster B. Cluster B is compatible with that virtual machine, and in case of a disaster recovery scenario the storage domain can be imported to the secondary setup, and the user can register the virtual machine to cluster B.
In that case, we can automate the recovery process by defining a cluster mapping. After the entity is registered, its OVF will indicate it belongs to cluster A, but the mapping will indicate that cluster A will be replaced with cluster B. Red Hat Virtualization Manager should do the switch and register the virtual machine to cluster B in the secondary site.
Cluster mapping is just one example, there are different types of mappings:
- Cluster mapping.
- LUN mapping.
- Role mapping.
- Domain mapping.
- Permissions mapping.
- Affinity Group mapping.
- Affinity Label mapping.
- Virtual NIC profile mapping.
Each mapping will be used for its specific OVF’s data once the register operation takes place in the Red Hat Virtualization Manager.
An example of an XML representation using the mapping:
<action> <registration_configuration> <cluster_mappings> <registration_cluster_mapping> <from> <name>myoriginalcluster</name> </from> <to> <name>mynewcluster</name> </to> </registration_cluster_mapping> </cluster_mappings> <role_mappings> <registration_role_mapping> <from> <name>SuperUser</name> </from> <to> <name>UserVmRunTimeManager</name> </to> </registration_role_mapping> </role_mappings> <domain_mappings> <registration_domain_mapping> <from> <name>redhat</name> </from> <to> <name>internal</name> </to> </registration_domain_mapping> </domain_mappings> <lun_mappings> <registration_lun_mapping> <from id="111"> </from> <to id="222"> <alias>weTestLun</alias> <lun_storage> <type>iscsi</type> <logical_units> <logical_unit id="36001405fb1ddb4b91e44078f1fffcfef"> <address>44.33.11.22</address> <port>3260</port> <portal>1</portal> <target>iqn.2017-11.com.name.redhat:444</target> </logical_unit> </logical_units> </lun_storage> </to> </registration_lun_mapping> </lun_mappings> <affinity_group_mappings> <registration_affinity_group_mapping> <from> <name>affinity</name> </from> <to> <name>affinity2</name> </to> </registration_affinity_group_mapping> </affinity_group_mappings> <affinity_label_mappings> <registration_affinity_label_mapping> <from> <name>affinity_label</name> </from> <to> <name>affinity_label2</name> </to> </registration_affinity_label_mapping> </affinity_label_mappings> <vnic_profile_mappings> <registration_vnic_profile_mapping> <from> <name>gold</name> <network> <name>red</name> </network> </from> <to id="738dd914-8ec8-4a8b-8628-34672a5d449b"/> </registration_vnic_profile_mapping> <registration_vnic_profile_mapping> <from> <name>silver</name> <network> <name>blue</name> </network> </from> <to> <name>copper</name> <network> <name>orange</name> </network> </to> </registration_vnic_profile_mapping> </vnic_profile_mappings> </registration_configuration> </action>

7.220. RegistrationRoleMapping struct
This type describes how to map roles as part of the object registration. An object can be a virtual machine, template, etc.
A role mapping is intended to map correlating roles between the primary site and the secondary site. For example, there may be permissions with role UserVmRunTimeManager
for the virtual machine that is being registered. Therefore we can send a mapping that will register the virtual machine in the secondary setup using the SuperUser
role instead of UserVmRunTimeManager
An example of an XML representation using this mapping:
<action> <registration_configuration> <role_mappings> <registration_eole_mapping> <from> <name>SuperUser</name> </from> <to> <name>UserVmRunTimeManager</name> </to> </registration_role_mapping> </role_mappings> </registration_configuration> </action>

If, for example, the desired virtual NIC profile mapping includes the following lines:
Source network name | Source network profile name | Target virtual NIC profile ID\names |
---|---|---|
|
|
|
|

7.240.1. cpu
The configuration of the virtual machine CPU.
The socket configuration can be updated without rebooting the virtual machine. The cores and the threads require a reboot.
For example, to change the number of sockets to 4 immediately, and the number of cores and threads to 2 after reboot, send the following request:
PUT /ovirt-engine/api/vms/123
With a request body:
<vm> <cpu> <topology> <sockets>4</sockets> <cores>2</cores> <threads>2</threads> </topology> </cpu> </vm>
7.240.2. custom_compatibility_version
Virtual machine custom compatibility version.
Enables a virtual machine to be customized to its own compatibility version. If custom_compatibility_version
is set, it overrides the cluster’s compatibility version for this particular virtual machine.
The compatibility version of a virtual machine is limited by the data center the virtual machine resides in, and is checked against capabilities of the host the virtual machine is planned to run on.
7.240.3. high_availability
The virtual machine high availability configuration. If set, the virtual machine will be automatically restarted when it unexpectedly goes down.
7.240.4. initialization
Reference to the virtual machine’s initialization configuration.
Since Red Hat Virtualization 4.1.8 this property can be cleared by sending an empty tag.
For example, to clear the initialization
attribute send a request like this:
PUT /ovirt-engine/api/vms/123
With a request body like this:
<vm> <initialization/> </vm>
The response to such a request, and requests with the header All-Content: true
will still contain this attribute.
7.240.5. large_icon
Virtual machine’s large icon. Either set by user or refers to image set according to operating system.
7.240.6. lease
Reference to the storage domain this virtual machine/template lease reside on.
A virtual machine running with a lease requires checking while running that the lease is not taken by another host, preventing another instance of this virtual machine from running on another host. This provides protection against split-brain in highly available virtual machines. A template can also have a storage domain defined for a lease in order to have the virtual machines created from this template to be preconfigured with this storage domain as the location of the leases.
7.240.7. memory
The virtual machine’s memory, in bytes.
For example, to update a virtual machine to contain 1 Gibibyte (GiB) of memory, send the following request:
PUT /ovirt-engine/api/vms/123
With the following request body:
<vm> <memory>1073741824</memory> </vm>
Memory hot plug is supported from Red Hat Virtualization 3.6 onwards. You can use the example above to increase memory while the virtual machine is in state up. The size increment must be dividable by the value of the HotPlugMemoryBlockSizeMb
configuration value (256 MiB by default). If the memory size increment is not dividable by this value, the memory size change is only stored to next run configuration. Each successful memory hot plug operation creates one or two new memory devices.
Memory hot unplug is supported since Red Hat Virtualization 4.2 onwards. Memory hot unplug can only be performed when the virtual machine is in state up. Only previously hot plugged memory devices can be removed by the hot unplug operation. The requested memory decrement is rounded down to match sizes of a combination of previously hot plugged memory devices. The requested memory value is stored to next run configuration without rounding.
Memory in the example is converted to bytes using the following formula:
1 GiB = 230 bytes = 1073741824 bytes.
Red Hat Virtualization Manager internally rounds values down to whole MiBs (1MiB = 220 bytes)
7.240.8. migration_downtime
Maximum time the virtual machine can be non responsive during its live migration to another host in ms.
Set either explicitly for the virtual machine or by engine-config -s DefaultMaximumMigrationDowntime=[value]
7.240.9. next_run_configuration_exists
Virtual machine configuration has been changed and requires restart of the virtual machine. Changed configuration is applied at processing the virtual machine’s shut down.
7.240.10. origin
The origin of this virtual machine.
Possible values:
-
ovirt
-
rhev
-
vmware
-
xen
-
external
-
hosted_engine
-
managed_hosted_engine
-
kvm
-
physical_machine
-
hyperv
7.240.11. persist_memorystate
Indicates if the content of the memory of the virtual machine is included in the snapshot.
When a snapshot is created the default value is true
.
7.240.12. placement_policy
The configuration of the virtual machine’s placement policy.
This configuration can be updated to pin a virtual machine to one or more hosts.
Virtual machines that are pinned to multiple hosts cannot be live migrated, but in the event of a host failure, any virtual machine configured to be highly available is automatically restarted on one of the other hosts to which the virtual machine is pinned.
For example, to pin a virtual machine to two hosts, send the following request:
PUT /api/vms/123
With a request body like this:
<vm> <high_availability> <enabled>true</enabled> <priority>1</priority> </high_availability> <placement_policy> <hosts> <host> <name>Host1</name> </host> <host> <name>Host2</name> </host> </hosts> <affinity>pinned</affinity> </placement_policy> </vm>
7.240.13. small_icon
Virtual machine’s small icon. Either set by user or refers to image set according to operating system.
7.240.14. sso
Reference to the Single Sign On configuration this virtual machine is configured for. The user can be automatically signed in the virtual machine’s operating system when console is opened.
7.240.15. stop_reason
The reason the virtual machine was stopped. Optionally set by user when shutting down the virtual machine.

Serves as the default value of |
7.259.1. backup
This attribute indicates whether a data storage domain is used as backup domain or not. If the domain is set to backup then it will be used to store virtual machines and templates for disaster recovery purposes in the same way we use export storage domain. This attribute is only available with data storage domain and not with ISO domain or export storage domain. User can use this functionality while creating a data storage domain or importing a data storage domain.
7.259.2. discard_after_delete
Indicates whether disks' blocks on block storage domains will be discarded right before they are deleted.
If true, and a disk on this storage domain has its wipe_after_delete
value enabled, then when the disk is deleted:
- It is first wiped.
- Then its blocks are discarded.
- Finally it is deleted.
Note that:
-
Discard after delete will always be
false
for non block storage types. -
Discard after delete can be set to
true
only if the storage domain supports discard.
7.259.3. supports_discard
Indicates whether a block storage domain supports discard operations. A storage domain only supports discard if all of the logical units that it is built from support discard; that is, if each logical unit’s discard_max_size
value is greater than 0. This is one of the conditions necessary for a virtual disk in this storage domain to have its pass_discard
attribute enabled.
7.259.4. supports_discard_zeroes_data
Indicates whether a block storage domain supports the property that discard zeroes the data. A storage domain only supports the property that discard zeroes the data if all of the logical units that it is built from support it; that is, if each logical unit’s discard_zeroes_data
value is true.
Since version 4.2.1 of the system, the support for this attribute has been removed as the sysfs file, discard_zeroes_data
, was deprecated in the kernel. It is preserved for backwards compatibility, but the value will always be false
.
7.259.5. wipe_after_delete
Serves as the default value of wipe_after_delete
for disks on this storage domain.
That is, newly created disks will get their wipe_after_delete
value from their storage domains by default. Note that the configuration value SANWipeAfterDelete
serves as the default value of block storage domains' wipe_after_delete

| Version 4 of the storage domain format. |
7.263.1. v1
Version 1 of the storage domain format is applicable to NFS, iSCSI and FC storage domains.
Each storage domain contains metadata describing its own structure, and all of the names of physical volumes that are used to back virtual machine disk images. Master domains additionally contain metadata for all the domains and physical volume names in the storage pool. The total size of this metadata is limited to 2 KiB, limiting the number of storage domains that can be in a pool. Template and virtual machine base images are read only.
7.263.2. v2
Version 2 of the storage domain format is applicable to iSCSI and FC storage domains.
All storage domain and pool metadata is stored as logical volume tags rather than written to a logical volume. Metadata about virtual machine disk volumes is still stored in a logical volume on the domains. Physical volume names are no longer included in the metadata. Template and virtual machine base images are read only.
7.263.3. v3
Version 3 of the storage domain format is applicable to NFS, POSIX, iSCSI and FC storage domains.
All storage domain and pool metadata is stored as logical volume tags rather than written to a logical volume. Metadata about virtual machine disk volumes is still stored in a logical volume on the domains. Virtual machine and template base images are no longer read only. This change enables live snapshots, live storage migration, and clone from snapshot. Support for Unicode metadata is added, for non-English volume names.

7.269.1. cpu
The configuration of the virtual machine CPU.
The socket configuration can be updated without rebooting the virtual machine. The cores and the threads require a reboot.
For example, to change the number of sockets to 4 immediately, and the number of cores and threads to 2 after reboot, send the following request:
PUT /ovirt-engine/api/vms/123
With a request body:
<vm> <cpu> <topology> <sockets>4</sockets> <cores>2</cores> <threads>2</threads> </topology> </cpu> </vm>
7.269.2. custom_compatibility_version
Virtual machine custom compatibility version.
Enables a virtual machine to be customized to its own compatibility version. If custom_compatibility_version
is set, it overrides the cluster’s compatibility version for this particular virtual machine.
The compatibility version of a virtual machine is limited by the data center the virtual machine resides in, and is checked against capabilities of the host the virtual machine is planned to run on.
7.269.3. high_availability
The virtual machine high availability configuration. If set, the virtual machine will be automatically restarted when it unexpectedly goes down.
7.269.4. initialization
Reference to the virtual machine’s initialization configuration.
Since Red Hat Virtualization 4.1.8 this property can be cleared by sending an empty tag.
For example, to clear the initialization
attribute send a request like this:
PUT /ovirt-engine/api/vms/123
With a request body like this:
<vm> <initialization/> </vm>
The response to such a request, and requests with the header All-Content: true
will still contain this attribute.
7.269.5. large_icon
Virtual machine’s large icon. Either set by user or refers to image set according to operating system.
7.269.6. lease
Reference to the storage domain this virtual machine/template lease reside on.
A virtual machine running with a lease requires checking while running that the lease is not taken by another host, preventing another instance of this virtual machine from running on another host. This provides protection against split-brain in highly available virtual machines. A template can also have a storage domain defined for a lease in order to have the virtual machines created from this template to be preconfigured with this storage domain as the location of the leases.
7.269.7. memory
The virtual machine’s memory, in bytes.
For example, to update a virtual machine to contain 1 Gibibyte (GiB) of memory, send the following request:
PUT /ovirt-engine/api/vms/123
With the following request body:
<vm> <memory>1073741824</memory> </vm>
Memory hot plug is supported from Red Hat Virtualization 3.6 onwards. You can use the example above to increase memory while the virtual machine is in state up. The size increment must be dividable by the value of the HotPlugMemoryBlockSizeMb
configuration value (256 MiB by default). If the memory size increment is not dividable by this value, the memory size change is only stored to next run configuration. Each successful memory hot plug operation creates one or two new memory devices.
Memory hot unplug is supported since Red Hat Virtualization 4.2 onwards. Memory hot unplug can only be performed when the virtual machine is in state up. Only previously hot plugged memory devices can be removed by the hot unplug operation. The requested memory decrement is rounded down to match sizes of a combination of previously hot plugged memory devices. The requested memory value is stored to next run configuration without rounding.
Memory in the example is converted to bytes using the following formula:
1 GiB = 230 bytes = 1073741824 bytes.
Red Hat Virtualization Manager internally rounds values down to whole MiBs (1MiB = 220 bytes)
7.269.8. migration_downtime
Maximum time the virtual machine can be non responsive during its live migration to another host in ms.
Set either explicitly for the virtual machine or by engine-config -s DefaultMaximumMigrationDowntime=[value]
7.269.9. origin

Possible values:
-
ovirt
-
rhev
-
vmware
-
xen
-
external
-
hosted_engine
-
managed_hosted_engine
-
kvm
-
physical_machine
-
hyperv
7.269.10. placement_policy
The configuration of the virtual machine’s placement policy.
This configuration can be updated to pin a virtual machine to one or more hosts.
Virtual machines that are pinned to multiple hosts cannot be live migrated, but in the event of a host failure, any virtual machine configured to be highly available is automatically restarted on one of the other hosts to which the virtual machine is pinned.
For example, to pin a virtual machine to two hosts, send the following request:
PUT /api/vms/123
With a request body like this:
<vm> <high_availability> <enabled>true</enabled> <priority>1</priority> </high_availability> <placement_policy> <hosts> <host> <name>Host1</name> </host> <host> <name>Host2</name> </host> </hosts> <affinity>pinned</affinity> </placement_policy> </vm>

The virtual machine’s memory, in bytes.
For example, to update a virtual machine to contain 1 Gibibyte (GiB) of memory, send the following request:
PUT /ovirt-engine/api/vms/123
With the following request body:
<vm> <memory>1073741824</memory> </vm>
Memory hot plug is supported from Red Hat Virtualization 3.6 onwards. You can use the example above to increase memory while the virtual machine is in state up. The size increment must be dividable by the value of the HotPlugMemoryBlockSizeMb
configuration value (256 MiB by default). If the memory size increment is not dividable by this value, the memory size change is only stored to next run configuration. Each successful memory hot plug operation creates one or two new memory devices.
Memory hot unplug is supported since Red Hat Virtualization 4.2 onwards. Memory hot unplug can only be performed when the virtual machine is in state up. Only previously hot plugged memory devices can be removed by the hot unplug operation. The requested memory decrement is rounded down to match sizes of a combination of previously hot plugged memory devices. The requested memory value is stored to next run configuration without rounding.
Memory in the example is converted to bytes using the following formula:
1 GiB = 230 bytes = 1073741824 bytes.
Red Hat Virtualization Manager internally rounds values down to whole MiBs (1MiB = 220 bytes)

7.288.11. placement_policy
The configuration of the virtual machine’s placement policy.
This configuration can be updated to pin a virtual machine to one or more hosts.
Virtual machines that are pinned to multiple hosts cannot be live migrated, but in the event of a host failure, any virtual machine configured to be highly available is automatically restarted on one of the other hosts to which the virtual machine is pinned.
For example, to pin a virtual machine to two hosts, send the following request:
PUT /api/vms/123
With a request body like this:
<vm> <high_availability> <enabled>true</enabled> <priority>1</priority> </high_availability> <placement_policy> <hosts> <host> <name>Host1</name> </host> <host> <name>Host2</name> </host> </hosts> <affinity>pinned</affinity> </placement_policy> </vm>

7.290.1. cpu
The configuration of the virtual machine CPU.
The socket configuration can be updated without rebooting the virtual machine. The cores and the threads require a reboot.
For example, to change the number of sockets to 4 immediately, and the number of cores and threads to 2 after reboot, send the following request:
PUT /ovirt-engine/api/vms/123
With a request body:
<vm> <cpu> <topology> <sockets>4</sockets> <cores>2</cores> <threads>2</threads> </topology> </cpu> </vm>
7.290.2. custom_compatibility_version
Virtual machine custom compatibility version.
Enables a virtual machine to be customized to its own compatibility version. If custom_compatibility_version
is set, it overrides the cluster’s compatibility version for this particular virtual machine.
The compatibility version of a virtual machine is limited by the data center the virtual machine resides in, and is checked against capabilities of the host the virtual machine is planned to run on.
7.290.3. high_availability
The virtual machine high availability configuration. If set, the virtual machine will be automatically restarted when it unexpectedly goes down.
7.290.4. initialization
Reference to the virtual machine’s initialization configuration.
Since Red Hat Virtualization 4.1.8 this property can be cleared by sending an empty tag.
For example, to clear the initialization
attribute send a request like this:
PUT /ovirt-engine/api/vms/123
With a request body like this:
<vm> <initialization/> </vm>
The response to such a request, and requests with the header All-Content: true
will still contain this attribute.
7.290.5. large_icon
Virtual machine’s large icon. Either set by user or refers to image set according to operating system.
7.290.6. lease
Reference to the storage domain this virtual machine/template lease reside on.
A virtual machine running with a lease requires checking while running that the lease is not taken by another host, preventing another instance of this virtual machine from running on another host. This provides protection against split-brain in highly available virtual machines. A template can also have a storage domain defined for a lease in order to have the virtual machines created from this template to be preconfigured with this storage domain as the location of the leases.
7.290.7. memory
The virtual machine’s memory, in bytes.
For example, to update a virtual machine to contain 1 Gibibyte (GiB) of memory, send the following request:
PUT /ovirt-engine/api/vms/123
With the following request body:
<vm> <memory>1073741824</memory> </vm>
Memory hot plug is supported from Red Hat Virtualization 3.6 onwards. You can use the example above to increase memory while the virtual machine is in state up. The size increment must be dividable by the value of the HotPlugMemoryBlockSizeMb
configuration value (256 MiB by default). If the memory size increment is not dividable by this value, the memory size change is only stored to next run configuration. Each successful memory hot plug operation creates one or two new memory devices.
Memory hot unplug is supported since Red Hat Virtualization 4.2 onwards. Memory hot unplug can only be performed when the virtual machine is in state up. Only previously hot plugged memory devices can be removed by the hot unplug operation. The requested memory decrement is rounded down to match sizes of a combination of previously hot plugged memory devices. The requested memory value is stored to next run configuration without rounding.
Memory in the example is converted to bytes using the following formula:
1 GiB = 230 bytes = 1073741824 bytes.
Red Hat Virtualization Manager internally rounds values down to whole MiBs (1MiB = 220 bytes)
7.290.8. migration_downtime
Maximum time the virtual machine can be non responsive during its live migration to another host in ms.
Set either explicitly for the virtual machine or by engine-config -s DefaultMaximumMigrationDowntime=[value]
7.290.9. origin
The origin of this virtual machine.

7.290.10. placement_policy
The configuration of the virtual machine’s placement policy.
This configuration can be updated to pin a virtual machine to one or more hosts.
Virtual machines that are pinned to multiple hosts cannot be live migrated, but in the event of a host failure, any virtual machine configured to be highly available is automatically restarted on one of the other hosts to which the virtual machine is pinned.
For example, to pin a virtual machine to two hosts, send the following request:

7.293.1. auto_storage_select
Indicates if the pool should automatically distribute the disks of the virtual machines across the multiple storage domains where the template is copied.
When the template used by the pool is present in multiple storage domains, the disks of the virtual machines of the pool will be created in one of those storage domains. By default, or when the value of this attribute is false
, that storage domain is selected when the pool is created, and all virtual machines will use the same. If this attribute is true
, then, when a virtual machine is added to the pool, the storage domain that has more free space is selected.
7.293.2. prestarted_vms
The system attempts to prestart the specified number of virtual machines from the pool.
These virtual machines are started without being attached to any user. That way, users can acquire virtual machines from the pool faster.
7.293.3. stateful
Virtual machine pool’s stateful flag.
Virtual machines from a stateful virtual machine pool are always started in stateful mode (stateless snapshot is not created). The state of the virtual machine is preserved even when the virtual machine is passed to a different user.

---|---|
| This policy indicates that virtual machines in the pool are automcatically deallocated by the system. |
| This policy indicates that virtual machines in the pool are deallocated manually by the administrator. |
7.294.1. automatic
This policy indicates that virtual machines in the pool are automcatically deallocated by the system.
With this policy, when a virtual machine that is part of the pool and is assigned to a user is shut-down, it is detached from the user, its state is restored to the pool’s default state, and the virtual machine returns to pool (i.e., the virtual machine can then be assigned to another user).
7.294.2. manual
This policy indicates that virtual machines in the pool are deallocated manually by the administrator.
With this policy, a virtual machine that is part of the pool remains assigned to its user and preserves its state on shut-down. In order to return the virtual machine back to the pool, the administrator needs to deallocate it explicitly by removing the user’s permissions on that virtual machine.
7.295. VmStatus enum
Type represeting a status of a virtual machine.
Table 7.386. Values summary
Name | Summary |
---|---|
| This status indicates that the virtual machine process is not running. |
| This status indicates that the virtual machine process is not running and there is some operation on the disks of the virtual machine that prevents it from being started. |
| This status indicates that the virtual machine process is running and the virtual machine is being migrated from one host to another. |
| This status indicates that the hypervisor detected that the virtual machine is not responding. |
| This status indicates that the virtual machine process is running and the virtual machine is paused. |
| This status indicates that the virtual machine process is running and it is about to stop running. |
| This status indicates that the virtual machine process is running and the guest operating system is being loaded. |
| This status indicates that the virtual machine process is running and the guest operating system is being rebooted. |
| This status indicates that the virtual machine process is about to run and the virtual machine is going to awake from hibernation. |
| This status indicates that the virtual machine process is running and the virtual machine is being hibernated. |
| This status indicates that the virtual machine process is not running and a running state of the virtual machine was saved. |
| This status is set when an invalid status is received. |
| This status indicates that the system failed to determine the status of the virtual machine. |
| This status indicates that the virtual machine process is running and the guest operating system is loaded. |
| This status indicates that the virtual machine process is about to run. |
7.295.1. paused
This status indicates that the virtual machine process is running and the virtual machine is paused. This may happen in two cases: when running a virtual machine is paused mode and when the virtual machine is being automatically paused due to an error.
7.295.2. powering_up
This status indicates that the virtual machine process is running and the guest operating system is being loaded. Note that if no guest-agent is installed, this status is set for a predefined period of time, that is by default 60 seconds, when running a virtual machine.
7.295.3. restoring_state
This status indicates that the virtual machine process is about to run and the virtual machine is going to awake from hibernation. In this status, the running state of the virtual machine is being restored.
7.295.4. saving_state
This status indicates that the virtual machine process is running and the virtual machine is being hibernated. In this status, the running state of the virtual machine is being saved. Note that this status does not mean that the guest operating system is being hibernated.
7.295.5. suspended
This status indicates that the virtual machine process is not running and a running state of the virtual machine was saved. This status is similar to Down, but when the VM is started in this status its saved running state is restored instead of being booted using the normal procedue.
7.295.6. unknown
This status indicates that the system failed to determine the status of the virtual machine. The virtual machine process may be running or not running in this status. For instance, when host becomes non-responsive the virtual machines that ran on it are set with this status.
7.295.7. up
This status indicates that the virtual machine process is running and the guest operating system is loaded. Note that if no guest-agent is installed, this status is set after a predefined period of time, that is by default 60 seconds, when running a virtual machine.
7.295.8. wait_for_launch
This status indicates that the virtual machine process is about to run. This status is set when a request to run a virtual machine arrives to the host. It is possible that the virtual machine process will fail to run.
7.296. VmStorageErrorResumeBehaviour enum
If the storage, on which this virtual machine has some disks gets unresponsive, the virtual machine gets paused.
This are the possible options, what should happen with the virtual machine in the moment the storage gets available again.

7.296.1. auto_resume
The virtual machine gets resumed automatically in the moment the storage is available again.
This is the only behavior available before 4.2.
7.296.2. kill
The virtual machine will be killed after a timeout (configurable on the hypervisor).
This is the only option supported for highly available virtual machines with leases. The reason is that the highly available virtual machine is restarted using the infrastructure and any kind of resume risks split brains.
7.296.3. leave_paused
Do nothing with the virtual machine.
Useful if there is a custom failover implemented and the user does not want the virtual machine to get resumed.
7.297. VmSummary struct

7.298.1. desktop
The virtual machine is intended to be used as a desktop.
Currently, its implication is that a sound device will automatically be added to the virtual machine.
7.298.2. high_performance
The virtual machine is intended to be used as a high performance virtual machine.
Currently, its implication is that the virtual machine configuration will automatically be set for running with the highest possible performance, and with performance metrics as close to bare metal as possible.
Some of the recommended configuration settings for the highest possible performance cannot be set automatically; manually setting them before running the virtual machine is recommended.
The following configuration changes are set automatically:
- Enable headless mode.
- Enable serial console.
- Enable pass-through host CPU.
- Enable I/O threads.
- Enable I/O threads pinning and set the pinning topology.
- Enable the paravirtualized random number generator PCI (virtio-rng) device.
- Disable all USB devices.
- Disable the soundcard device.
- Disable the smartcard device.
- Disable the memory balloon device.
- Disable the watchdog device.
- Disable migration.
- Disable high availability.
The following recommended configuration changes have to be set manually by the user:
- Enable CPU pinning topology.
- Enable non-uniform memory access (NUMA) pinning topology.
- Enable and set huge pages configuration.
- Disable kernel same-page merging (KSM).
7.298.3. server
The virtual machine is intended to be used as a server.
Currently, its implication is that a sound device will not automatically be added to the virtual machine.

| Enables passthrough to an SR-IOV-enabled host NIC. | |
| Enables port mirroring. |
7.301.1. migratable
Marks whether pass_through
NIC is migratable or not.
If pass_through.mode
is set to disabled
this option has no meaning, and it will be considered to be true
. If you omit this option from a request, by default, this will be set to true
.
When migrating a virtual machine, this virtual machine will be migrated only if all pass_through
NICs are flagged as migratable
.
7.301.2. pass_through
Enables passthrough to an SR-IOV-enabled host NIC.
A vNIC profile enables a NIC to be directly connected to a virtual function (VF) of an SR-IOV-enabled host NIC, if passthrough is enabled. The NIC will then bypass the software network virtualization and connect directly to the VF for direct device assignment.
Passthrough cannot be enabled if the vNIC profile is already attached to a NIC. If a vNIC profile has passthrough enabled, qos
and port_mirroring
are disabled for the vNIC profile.
7.301.3. port_mirroring
Enables port mirroring.
Port mirroring copies layer 3 network traffic on a given logical network and host to a NIC on a virtual machine. This virtual machine can be used for network debugging and tuning, intrusion detection, and monitoring the behavior of other virtual machines on the same host and logical network. The only traffic copied is internal to one logical network on one host. There is no increase in traffic on the network external to the host; however a virtual machine with port mirroring enabled uses more host CPU and RAM than other virtual machines.
Port mirroring has the following limitations:
- Hot plugging a NIC with a vNIC profile that has port mirroring enabled is not supported.
- Port mirroring cannot be altered when the vNIC profile is attached to a virtual machine.
Given the above limitations, it is recommended that you enable port mirroring on an additional, dedicated vNIC profile.
Enabling port mirroring reduces the privacy of other network users.
