Previously, VDSM only reported physical cores by default. An update allowed users to manually force VDSM to report threads instead of physical cores. Now, clusters can be configured to treat host CPU threads as cores for the purposes of virtual machine resource allocation and migration. 

Users who had previously forced VDSM to report threads should revert to the configuration of reporting physical cores. If VDSM only reports physical cores, Red Hat Enterprise Virtualization Manager will assume hyperthreading is disabled on the hosts in the cluster, and thus not allow host memory optimization.
When making configuration changes using the rhevm-config tool it is necessary to restart the ovirt-engine service before they will take effect. Additionally changes to values that are cached on the client side require a restart of the client browser to clear cached values before they will take effect.
The Force Remove data center option should only be used after the storage is no longer needed or has been destroyed. If you have leftover data on the storage, manually remove any files under /rhev/data-center, and unmount any mount points that exist there.
Internet Explorer 8 treats the <iframe src="javascript:''" ...> tag as a non-secure item, which causes a Mixed Content pop-up warning, and a delay in installing SPICE ActiveX plugins on the user portal. To prevent this behavior, configure Internet Explorer 8 to suppress mixed content warnings using the Internet Options → Security Settings. See http://msdn.microsoft.com/en-us/library/ee264315(v=vs.85).aspx for details.
If you are using the JBoss Application Server from JBoss Enterprise Application Platform 6.0.1, upgrading the Red Hat Enterprise Virtualization Manager will not automatically update the application server to EAP 6.1. Although Red Hat Enterprise Virtualization Manager supports EAP 6.0.1, it is recommended to update to the latest supported JBoss version. To upgrade to JBoss EAP 6.1, see https://access.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/6.1/html/Installation_Guide/Upgrade_the_JBoss_Enterprise_Application_Platform_6_RPM_Installation.html.
Due to the performance constraints imposed by the JavaScript engine included in Internet Explorer 8 it is not a supported client for the new Administration Portal user interface. Later versions of Internet Explorer remain supported.
The Always use the cursor keys to navigate within pages Firefox option does not work as expected for keyboard-triggered functions in the administration portal, for example when using arrow keys to select items in the Search bar. This option is disabled by default, and it is recommended to keep it that way. More information on this Firefox option can be found at http://support.mozilla.org/en-US/kb/accessibility-features-firefox-make-firefox-and-we#w_always-use-the-cursor-keys-to-navigate-within-webpages.
After a Red Hat Enterprise Virtualization Hypervisor is attached to the Red Hat Enterprise Virtualization Manager and then successfully upgraded, it may erroneously appear in the administration portal with the status of Install Failed. Click on the Activate button, and the hypervisor will change to an Up status and be ready for use.
Importing diskless virtual machines or templates will fail, or be imported without peripheral device such as network devices. To work around this issue, redefine diskless virtual machines or templates in the destination. Do not use the export and import process.
Previously, the time zone for a Red Hat Enterprise Linux virtual machine could be set in the Initial Run tab of the New or Edit Virtual Machine window. Now, the default time zone which is Etc/GMT is used, and it cannot be changed via the administration portal. After an upgrade, the time zones of all Red Hat Enterprise Linux virtual machines are reset to Etc/GMT. If you are using a Linux virtual machine with a non-default time zone, adjust the machine's hardware clock to your desired time zone.
When moving a disk between two storage domains with different quotas (or the same quota set for each specific storage domain) the source quota resources are released while the destination quota resources are consumed. If the quota is refreshed or edited, or if the engine is restarted, the quota accounting is rolled back until the move operation is done. This function is offered as a technology preview.
Upgrading the rhevm-dwh package produces an error which prevents the database warehouse service from starting. To work around this issue, turn off the rhevm-dwhd service before upgrading, then start it after the upgrade has completed.
The --storage_format option is an accepted argument for the add storagedomain command, even though it does not appear in the list of available options.
The --parent-tag-id and --parent-tag-name options are accepted arguments for the add tag command, even though they do not appear in the list of available options.
The --format option must be passed for the storage domain to be removed, however the remove storagedomain command does not list the --format option as a required argument.
A Red Hat Enterprise Virtualization 3.1 data center containing both Gluster-enabled clusters and virtualization host clusters cannot be upgraded to Red Hat Enterprise Virtualization 3.2. Currently, Red Hat Enterprise Virtualization 3.2 is not compatible with Red Hat Storage 2.0, so Gluster clusters can only be used with 3.1-compatible data centers.
A new native multiple monitor feature using a single QXL device for Red Hat Enterprise Linux virtual machines is included in the latest version of mingw-virt-viewer available in Red Hat Enterprise Virtualization 3.2. However, on Red Hat Enterprise Linux virtual machines multiple QXL devices are still created with not enough memory for a single QXL device, which can cause the multi-monitor feature to misbehave. 

To work around this issue, do not enable native multi-monitor support on your Linux virtual machines until this issue is fixed. Instead, use the Xinerama Xorg extension to manage Red Hat Enterprise Linux virtual machines with multi-monitor enabled.
Previously, when using the new Native USB Policy mode, connected USB devices were always shared regardless of whether the Enable USB Auto-Share option was selected. This issue has been resolved, and USB devices are correctly shared according to their setting in the Enable USB Auto-Share field.
Previously when VDSM attempted to run getFloppyList on an NFSv4 storage domain an error was returned if the permissions of the NFS export were not set correctly, or if the VDSM host was in a different NFS domain to the storage server. This has now been fixed, and the getFloppyList command succeeds as expected.
Previously, it was possible to move a virtual machine disk with a snapshot in preview mode, which caused a vdsm error, so the virtual machine could not run until the preview was reverted. An additional validation has been added to MoveDisksCommand to prevent such action.
Previously, the vdsmd service could be restarted by the spmprotect script, which triggered an attempt to restore the host network configuration to its last known safe state. If the host lost its Storage Pool Manager role, it would lose its current network connectivity. Now, the host network configuration is only restored on boot time, not when the vdsmd service is restarted. As a result, the service vdsmd restart command does not adversely affect host networking.
Previously, VDSM did not report errors to the Manager if the ifup script failed, for example when another host on the LAN has the same IP address. Now, ifup has to execute successfully for the setupNetwork command to succeed, otherwise VDSM reports the failure to the Manager.
If a virtual machine had a different number of network interfaces in normal mode and in snapshot preview mode, unused MAC addresses in either mode would be released to the pool. This meant that the same MAC address could potentially be assigned to network interfaces belonging to different virtual machines. With this update, a check is performed when a network interface is being plugged to ensure that it is not assigned an already used MAC address.
Disk alias are mandatory on Red Hat Enterprise Virtualization Manager in order to run virtual machines, but they are not mandatory in the OVF format. Now, aliases are auto-generated for disks imported from an OVF that does not contain aliases, so virtual machines imported from other sources can successfully run on Red Hat Enterprise Virtualization Manager.
Aliases for disks imported from OVFs were not generated correctly, as the disks were given identical names. Now, each disk is given a name and a number in ascending order. For example, the aliases generated for three disks belonging to virtual machine VmName are VmName_Disk1, VmName_Disk2, and VmName_Disk3.
Previously, the administration portal took several seconds to reflect changes to a virtual machine's disk properties. Now, the virtual machine's Disks tab is refreshed immediately the disk's properties are edited.
Previously, virtual machine which contained shareable disks could not be exported because the export command did not recognise shared disks. The export command now accounts for shared disks, so virtual machines with shared disks are exported successfully.
To create a Fibre Channel storage domain on a CCISS device, a scsi_disk path was used to retrieve Host, Bus, Target, Lun (HBTL) values which did not exist on CCISS devices. Consequently, the storage domain could not be created. Now, the HBTL value is not required for non-SCSI devices, so creating a storage domain on a CCISS device succeeds.
When a Fibre Channel storage domain was created from a host that was not the Storage Pool Manager (SPM), the SPM failed to recognise the storage domain and could not attach it. Now, when the domain cannot be attached, the SPM scans for new domains and retries to attach the domain until it succeeds.
Previously, dd was used to export virtual machines with snapshots, so the image size on the export domain was larger than the original image. Now, qemu-img convert is used to copy a RAW volume from the source domain to the destination domain, therefore the exported image remains sparse.
Previously, when an ISO domain lost SPM connectivity, the connection to the ISO domain could not be restored even though the mount point was available. A patch to VDSM ensures that the ISO domains are autorecovered after their connectivity is restored.
Previously, removing a file storage domain did not remove its lease files, so the virtual machines on the storage domain could not be deleted. Now, VDSM renames the lease files when a storage domain is removed, so its virtual machines can be deleted.
Previously, users could set the Do Not Migrate parameter on a virtual machine without defining a specific host to run the virtual machine, so the virtual machine could still be migrated. Now, when these conditions are met, the virtual machine's CPU will be pinned on the first host on which it runs. The virtual machine will not be migrated to other hosts.
Previously the web browser sent HTTP Authorization headers for all requests to a given origin after the header has already been set for the initial request. This meant the user interface plugin infrastructure acquired a REST API session using web administration portal user credentials including domain and password information, and the session was kept alive until the user signed out of the administration portal.

To work around this issue, all user interface plugins now receive a single shared session ID based on the web administration portal user login credentials. This session times out after six hours, and the administration portal will not attempt to keep this session alive using periodic heartbeat requests. 

The plugin is in charge of keeping its session alive, and if no plugin interacts with the REST API session via the provided ID for more than six hours, the session will time out.
