| Doc Text: |
Previously, if a migrating virtual machine thread acquired a resource lock but failed for some reason, it would not properly release the lock. This caused other threads to fail while acquiring locks to perform operations like migrate/Run VM. Now, a patch has fixed the regression that caused VMs to remain locked after failed migration.

how this bug should be verified please? For verification used av10.2 Hosts rhel6, rhel7 with up to date VDSM Steps: 1. Migrate 2 VMs from host1(SPM) to host2 2. While migration in process move host2 to maintenance 3. Wait for Migration to Fail and see in logs if locks were successfully freed 2014-07-18 11:03:03,168 INFO [org.ovirt.engine.core.bll.MigrateVmToServerCommand] (org.ovirt.thread.pool-4-thread-25) [47572d25] Lock Acquired to object EngineLock [exclusiveLocks= key: e3c73b01-1900-4b24-bfa7-e75b17e9dc0d value: VM , sharedLocks= ] 2014-07-18 11:03:03,168 INFO [org.ovirt.engine.core.bll.MigrateVmToServerCommand] (org.ovirt.thread.pool-4-thread-36) [6e952ea4] Lock Acquired to object EngineLock [exclusiveLocks= key: 4d7aa507-1b32-4618-a5a2-884500dbbbc1 value: VM , sharedLocks= ] 2014-07-18 11:03:07,433 INFO [org.ovirt.engine.core.bll.MigrateVmToServerCommand] (org.ovirt.thread.pool-4-thread-2) [23c7912b] Lock freed to object EngineLock [exclusiveLocks= key: 4d7aa507-1b32-4618-a5a2-884500dbbbc1 value: VM , sharedLocks= ] 2014-07-18 11:03:07,435 INFO [org.ovirt.engine.core.bll.MigrateVmToServerCommand] (org.ovirt.thread.pool-4-thread-5) [23c7912b] Lock freed to object EngineLock [exclusiveLocks= key: e3c73b01-1900-4b24-bfa7-e75b17e9dc0d value: VM , sharedLocks= ] 4. Activate host2 again and try to migrate VMs to it (successful) 5. Tried migration on host3 (rhevh) also successful 6. Actions like like Shutdown/Pause/Start VM should pass as well as the lock is freed please verify these steps, once the steps will be approved by Arik I will move this bug to VERIFIED Thanks looks ok Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
