 After a frozen migration attempt, we have two VM that after shutdown, = are not

what do you mean by frozen? Are you talking about "VM live migration" or =
=E2=80=9Clive storage migration=E2=80=9D?
How exactly did you resolve that situation, you only shut down those =
VMs? No other troubleshooting steps, e.g. restarting engine, hosts, =
things like that?

Thanks,

 Probably this is caused by a wrong pointer into the database that = still refer to

 If we search within all_disks view, we can find that parentid field = isn't
