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.
