And again the only solution to get the virtual machine back was to set the
hypervisor host into maintenance, which does not completely work because the VM
will stay on the host for ovirt and then reboot the host, after the reboot the
virtual machine will be ok again (or restarted of configured to be highly
acvailable)
This is a huge problem, using a GUI command that causes the need to reboot a
complete hypervisor really worries me.

Soeren
