well, hacking the db will work, but reproducing this and logs for us to
fix the actually bug would also help.
We have seen this before, and we thought it was fixed.
Alan, can you describe exactly the sequence of events that leaded to
this problem? When you say that the host died while going to maintenance
what do you mean exactly? It crashed, rebooted, hung, was fenced? It
would be very helpful if you have the engine logs at the time the host
went down.
Once you have those logs in a safe place, the only way to get the VM out
of that status is to update the database manually. First make completely
sure that the VM is not running in any host, then do the following:
# psql -U engine
psql (9.1.6)
Type "help" for help.
engine=> update vm_dynamic set status = 0 where vm_guid = (select
vm_gui from vm_static where vm_name = 'myvm');
UPDATE 1
(Assuming that the name of your VM is "myvm").
