Ok I found the ERROR: After upgrade the schedule policy was "none", I dont know why it was moved to none but to fix the problem I did following: Edit Cluster->Scheduling Policy-> Select Policy: vm_evently_distributed Now I can run/migrate the VMs.
I think there should be a some bug in the upgrade process.
Well, if you would like to help us to find the cause then we need to know more details. - what was your original version? - what was your original scheduling policy on the cluster - could you provide * /var/log/ovirt-engine/setup/ovirt-engine-setup-20170801112218-piffzl.log * /var/log/ovirt-engine/engine.log You have backup of your original engine DB in /var/lib/ovirt-engine/backups/, thus you can import this DB via psql into a temporary DB and inspect the DB for original settings. Ideally you can submit a BZ at https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt j.
Sorry, I forgot to mention the error. This error throws every time when I try to start the VM:
