Thanks for the info Alessandro!

This seems like the best way to run cinder/ceph, using other storage for
these vms, so cinder vm does not depend on the vm managing the
storage it runs on.

If you use highly available vms, ovirt will make sure they are up all the time,
and will migrated them to other hosts when needed.
