Hi David,
Yes - this one will remove completely the VM from the DB.
You can use the virsh command to delete the VM guests:

Hi Shani,
These VMs in particular are running just fine on other hosts (and
I'd like to keep them that way, preferably).
It looks like this command would delete the whole VM from the
entire system instead of just removing the stuck/shutdown instances
from the hosts it's not running on any more.
Can you confirm this is what it would do? If so, is there another
option to remove these stuck "ghost" VM instances from the hosts they are
no longer running on?
Thanks
David
