I looked at the logs log and only vdsm from node2 (which appears to be the src node) seems to have full info. Please attach the following complete logs: vdsm log from dst node engine log libvirt logs from both nodes. Also, can you please answer the following? libvirt and vdsm you are using? what is selinux status on both hosts (enforcing/permissive)? do you have snapshots on the vm or does it happen on a newly created disk? when you create the disk, is it from a template or is it a new image?

The problem is that it doesn't say which process...
this looks like noise post the migration failing, with probably a more relevant error in libvirt log

Hi Meital
I tried to migrate another VM and it also failed.
This is what I get in UI:
Migration started (VM: nophpapp01, Source: novmnode1, Destination: novmnode2, User: edgarsm). Migration failed due to Error: Fatal error during migration. Trying to migrate to another Host (VM: nophpapp01, Source: novmnode1, Destination: novmnode2). Migration failed due to Error: Fatal error during migration (VM: nophpapp01, Source: novmnode1, Destination: novmnode2).
There is nothing in /var/log/messages, neither on engine server nor nodes.
See attachments for engine and vdsm logs. (I am migrating from vmnode1 to vmnode2)
whatever the issue is here, can you please open a bug on trying to return more info to user on the migration error itself (for easier troubleshooting).
thanks, Itamar
Thanks for the help Edgars

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

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?
