Hi Andrej,
I missed to point a fact that is probably determining. Prior to noticing
the error, we upgraded the Cluster & Data Center compatibility version
from 4.1 to 4.3, which caused ovirt-engine to automatically edit all VMs
and modify their compatibility versions as well (with changes pending
until next reboot).
So if we powered down the VM, edited the VM, saved it (even without
changes) and powered it up, migrations would work again.
This happened with all affected machines.
If you need some additional info, just ask.
Thanks.
