[ovirt-users] Problem migration VM

[Luca Bertoncello]

Hi list!

Sorry fort the previous E-Mail... problem on my Outlook... :(
Here again...

After a "war-week" I finally got a systemd-script  to put the host in
"maintenance" when a shutdown will started.
Now the problem is, that the automatically migration of the VM does NOT
work...

I see in the Web console the host will "Preparing for maintenance" and the
VM will start the migration, then the host is in "maintenance" and a couple of
seconds later the VM will be killed on the other host...

In the Log of the engine I see:

2015-09-23 11:14:17,165 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (org.ovirt.thread.pool-8-thread-30) [683624fe] Correlation ID: 52938d4d, Job ID: c0efe5b9-0bc3-4c81-9ee7-63ddf90a6afc, Call Stack: null, Custom Event ID: -1, Message: Mig
ration failed  while Host is in 'preparing for maintenance' state.
  Consider manual intervention: stopping/migrating Vms as Host's state will not
  turn to maintenance while VMs are still running on it.(VM: TestVM, Source: vmhost06, Destination: vmhost03).

(see http://pastebin.com/3Ca8W3vE)
On the host I see these two errors:

Can someone help me finding the problem?

Thanks
