Hello Arik,
we have upgrade one of our oVirt engines to 4.2.1 (from 4.1.9)
and afterwards all nodes too. The cluster compatibility level
has been set to 4.2.
Now we can't start a VM after it has been powered off. The only
hint we found in engine.log is:

But this doesn't lead us to the root cause. I haven't found any
matching bug tickets in release notes for upcoming 4.2.1. Can
anyone help here?
What's the mac address of that VM?
You can find it in the UI or with:
select mac_addr from vm_interface where vm_guid in (select vm_guid
from vm_static where vm_name='<vm_name>');
Actually, different question - does this VM has unplugged network interface?
The VM has two NICs. Both are plugged.
The MAC addresses are 00:1a:4a:18:01:52 for nic1 and
00:1a:4a:36:01:67 for nic2.
Regards
Jan
