[ovirt-users] Fenced hosts VM's never migrate

I have a 3 host cluster setup with HA enabled and fencing enabled and it
appears to be working properly.  Executing power management stop, start,
and restart work along with host shutdown/restart following a simulated
crash.  When network is pulled a proxy is chosen and it powers off the
downed host, and then restarts it.  Since the network is still down it
repeats the following in events:
"Host kvm01 is not responding. It will stay in Connecting state for a grace
period of 162 seconds and after that an attempt to fence the host will be
issued."

The real problem here is that the VM's on the host that has failed never
migrate to a new host and remain down until the network is reconnected.

We have tested this with back-end storage on gluster and NFS with the same
result.  This is on oVirt Engine Version: 3.5.1.1-1.el6.  Hosts are on
CentOS 7 and the Engine is standalone on CentOS 6.6.
