hello,
right now I restarted ovirt-engine and postgresql and my VMs disappeared
again, but not all of them! Some of them persists. (two) And I get
messages about failed export and import of those who disappeared. Than I
restored postgresql from backup and everything is OK. Restarting
postgresql is like using way back machine ;-)
