Hi,
I found workaround for this situation. There is a possibility to change 
the VM status manually in database:

update vm_dynamic set status=0 where 
vm_guid='1d5342a3-9375-49c5-bf2a-2bd444d41d09';

@oVirt developers
It seems that in some situations, VM with'unknown' status has no chances 
to change state. When all hosts in data center are up and the VM is not 
attached to any host it's a dead end. In this particular situation oVirt 
engine administrator can't perform any actions on "lost" VM. Is any way 
to handle this case without database access?

Best regards,
Piotr

Can you give me more information on how you're able to do this? I have an issue now. My VMs show "Unknown" status, too.
If I give you remote access, can you change the status on the VMs for me?

Thanks,
Chris
