[Users] VM Migration failed

Hi I am experiencing issues with manual VM migration. VM fails to migrate to other node in the same Cluster. Here are some relevant engine.log entries: ERROR [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-73) Rerun vm a31cfd62-26fc-4396-8a83-1aed68c7fd39. Called from vds novmnode1 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.MigrateStatusVDSCommand] (pool-6-thread-49) Failed in MigrateStatusVDS method ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.MigrateStatusVDSCommand] (pool-6-thread-49) Error code migrateErr and error message VDSGenericException: VDSErrorException: Failed to MigrateStatusVDS, error = Fatal error during migration ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.MigrateStatusVDSCommand] (pool-6-thread-49) Command MigrateStatusVDS execution failed. Exception: VDSErrorException: VDSGenericException: VDSErrorException: Failed to MigrateStatusVDS, error = Fatal error during migration Both Engine and Node are running CentOS 6.5 x64. oVirt Engine Version: 3.3.2-1.el6. VDSM version 4.13.2-1. I restarted engine and vdsm, that did not help. Also in vdsm log file I see the following errors related to the same VM ID: Thread-27::ERROR::2014-01-17 16:37:06,271::sampling::355::vm.Vm::(collect) vmId=`a31cfd62-26fc-4396-8a83-1aed68c7fd39`::Stats function failed: <AdvancedStatsFunction _highWrite at 0x26efb58> Any hints?
