Yes, it needs to be fenced.


Regarding the topic of this mail which grabbed my attention.
when I think about HA and oVirt I think about the following :

- oVirt Engine/RHEV-M can failover to an other host
- The shared storage is also available on the other side.

I've been testing migrating Engine in case it fails in a POC
by putting Engine in a KVM VM under control of pacemaker and 
DRBD to drop the need of shared storage.

The storage part is something I haven't found a solid solution
for.  Maybe with DRBD, but there must be a better way i think.
