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.
