 was the VM started in a 3.6 cluster? sure, on a full 3.6 cluster. I
stopped/restarted them. I restarted vdsmd=20
and libvirtd
...
 Or how/when did you create it? those vms have been created
before uprading to 3.6, some of them from a=20
blank template, other one based on a el7 template.
...

 Thanks,
 michal
