iirc, there is a corner case with a single host in DC around this fixed 
post ovirt 3.2 (http://gerrit.ovirt.org/#/c/13045/),
but if you rebooted the host, and it is back up, engine shouldn't have 
an issue connecting to VDSM and detecting the VMs are no longer running.

if the host/vdsm are up and running, and host is activated in engine - 
what status is it at?
