It may be worth pointing out that these are not limitations of libvirt
(which can even live-migrate VMs between non-shared storage), but only of
oVirt. The impression I've got from this mailing list is they are
intentional design decisions to enforce "correctness" of the cluster.
I do feel like it comes up often enough on the mailing list that it would
be nice if there was a way to designate a multi-host cluster as having
both local and shared storage. I think the flexibility would help those
running dev or small prod clusters. Maybe someone just needs to step up
and write a patch for it?
