Hi, I have problems with nova live-migration for my CentOS7 and RHEL7 VMs. The live migrations works fine for Windows2012R2 and Ubuntu1404 VMs.
For CentOS7/RHEL based images I get this error in the Destination node in nova-compute.log. Also console for logged in VM users on the VM freeze. 2016-09-28 10:49:24.101 353935 INFO nova.compute.manager [instance: cd0b605d] VM Resumed (Lifecycle Event) 2016-09-28 10:49:24.339 353935 INFO nova.compute.manager [instance: cd0b605d] VM Resumed (Lifecycle Event) 2016-09-28 10:49:25.866 353935 INFO nova.compute.manager [instance: cd0b605d] Post operation of migration started 2016-09-28 10:49:39.410 353935 INFO nova.compute.manager [instance: cd0b605d] VM Stopped (Lifecycle Event) *2016-09-28 10:49:39.532 353935 WARNING nova.compute.manager [instance: cd0b605d] Instance shutdown by itself. Calling the stop API.

Eventually the VM ends up in SHUTDOWN state on the destination node. I'm on CentOS7/Liberty, and my storage backend is CEPH(Hammer 0.94.9). Please advice. thx will
