[Users] host non responsive in a 1 host DC with 1 vm

Hi guys, I've got a test oVirt setup with only 1 host and 1 test VM but I had a power failure and the host is now non responsive, despite being able to log into it via SSH. Manually fencing results in a.... "Manual fence did not revoke the selected SPM (ovirthosttest) since the master storage domain was not active or could not use another host for the fence operation." When I try put the host into maintenance I get ..."Manual fence did not revoke the selected SPM (ovirthosttest) since the master storage domain was not active or could not use another host for the fence operation." When I try and activate the data domain I get... "Failed to activate Storage Domain MAIN (Data Center Default) by admin@internal". My VM was in an unknown state, but considering I'd already had a power failure, I logged into my oVirt engine postgres command line and ran "update vm_dynamic set status = 0 where vm_guid = (select vm_guid from vm_static where vm_name = 'zimbra');" to try and force my VM into a down state, but that hasn't helped either. I'd imagine that if I had another host to add to the cluster SPM would hopefully move to the new host and the problem would disappear, but I don't have one unfortunately. Any suggestions?

I could can the entire install and start again, but I'd prefer to avoid doing that if possible as I'm still in the process of migrating email to my zimbra VM. Any help is appreciated greatly. Thanks.
