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.
