Some concepts from IBM PowerHA look interesting:<br>

<blockquote>I don't know if the term is correct but we'd like to
be able to group vm's together and create dependency's between
them. Something like, first start the database vm then the
authentication vm and last the webserver vm.<br>

each site is located at a different geographical location.
Typically, the sites are far enough apart so that they
cannot conveniently share a common storage area network
(SAN). Each site must have its own active repository disk,
and any backup repositories. Linked clusters always use
unicast to communicate between sites. Linked clusters are a
useful part of high availability disaster recovery (HADR).</span></i><br>
