Hi,
I am testing the VM migration in oVirt engine 3.1 bteta release and successfully did the migration test on NFS date center. However, the test of VM migration on iSCSI data center failed. I dumped the error and warning segments from the vdsm logs on both the source and destination host. Please ignore the time stamp out of sync between the two hosts.
The vdsm log segment from the source host:

The destination host doesn't look right (9.181.129.110). Can you post the logs related to the vmMigrate parameters? Eventually you could open a bug so that you can attach the full logs.
