HA does not mean multiple running instances of the same service. It means if the service is gone, it will automatically be restored on a working server. That is a pretty narrow definition of HA, which is not shared by most parts of the community (and the world), leading to much confusion of users on this very ML.
HA in general means your service downtime gets minimized, today mostly realized through load balancing and clustering software services.
just restarting a service (in this case ovirt-engine vm) on a different host is not what todays user expect under the term "HA" imho.
in theory it should be possible as a design goal to make multiple ovirt-engine share one remote data base (remote database support is already there).
I think this would be a huge feature for ovirt, but also requires quite some design and coding to be done.
thus adding the devel list.
Please open RFE with this and we can consider that for future versions.
See: http://www.ovirt.org/Features/Engine_High_Availability Engine's PostgreSQL DB should also be replicated in a master-master fashion.
