</action>
This action updates all specified host network resources with standard NIC elements. The request includes additional elements specified in the following table.

Table 14.14. Elements for multiple host network interface setup

Element Type Description
modified_bonds complex Creates or updates bonds. Each host_nic element contains standard bonding elements. See Section 14.7.2.2, “Bonded Interfaces”.
removed_bonds complex An ID list of bonds to remove.
modified_network_attachments complex Adds or updates network attachments on the host. Each network_attachment element contains standard host network_attachment elements. See Section 14.7.1, “Host Network Attachments Sub-Collection”. Changing the host_nic ID moves the network to a different network interface card.
synchronized_network_attachments complex An ID list of out-of-sync network attachments to synchronize with the logical network definition of the data center.
removed_network_attachments complex An ID list of network attachments to remove.
modified_labels complex Creates or modifies labels. Each label element contains a label id (when creating a label) and a host_nic identified by a name or ID. Changing the host_nic ID moves the label to a different network interface card.
removed_labels complex An ID list of labels to remove.
checkConnectivity Boolean Set to true to verify connectivity between the host and the Red Hat Virtualization Manager. If the connectivity is lost, Red Hat Virtualization Manager reverts the settings.
connectivityTimeout integer Defines the timeout for loss of connectivity.

14.8.4. Fence Host Action

An API user controls a host's power management device with the fence action. The capabilities lists available fence_type options.

Example 14.31. Action to fence a host

POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/fence
Accept: application/xml
Content-Type: application/xml

<action>
    <fence_type>start</fence_type>
</action>

14.8.5. Deactivate Host Action

Deactivate the host to perform maintenance tasks.

Example 14.32. Action to deactivate a host

POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/deactivate HTTP/1.1
Accept: application/xml
Content-type: application/xml

<action/>

14.8.6. Host iSCSI Login Action

The iscsilogin action enables a host to login to an iSCSI target. Logging into a target makes the contained LUNs available in the host_storage collection.

Example 14.33. Action to enable a host to login to iSCSI target

POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/iscsilogin HTTP/1.1
Accept: application/xml
Content-Type: application/xml


<action>
    <iscsi>
        <address>mysan.example.com</address>
        <target>iqn.2009-08.com.example:mysan.foobar</target>
        <username>jimmy</username>
        <password>s3kr37</password>
    </iscsi>
</action>

14.8.7. Host iSCSI Discover Action

The iscsidiscover action enables an iSCSI portal to be queried for its list of targets.

Example 14.34. Action to query a list of targets for iSCSI portal

POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/iscsidiscover HTTP/1.1
Accept: application/xml
Content-Type: application/xml

<action>
    <iscsi>
        <address>mysan.example.com</address>
        <port>3260</port>
    </iscsi>
</action>

14.8.8. Commit Host Network Configuration Action

An API user commits the network configuration to persist a host network interface attachment or detachment, or persist the creation and deletion of a bonded interface.

Example 14.35. Action to commit network configuration

POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/commitnetconfig HTTP/1.1
Accept: application/xml
Content-type: application/xml

<action/>

Important

Networking configuration is only committed after the Manager has established that host connectivity is not lost as a result of the configuration changes. If host connectivity is lost, the host requires a reboot and automatically reverts to the previous networking configuration.

14.8.9. Setting SPM

Manually set a host as the Storage Pool Manager (SPM).

Example 14.36. Action to Set Host as SPM

POST /ovirt-engine/api/hosts/2ab5e1da-b726-4274-bbf7-0a42b16a0fc3/forceselectspm HTTP/1.1
