It'll be quite a while (and the new locking scheme I'm working on will not
include remote command execution.)

Apart from using ovirt/rhev, I'd try one of the following behind the
libvirt locking api: sanlock, dlm, file locks on nfs, file locks on gfs2.
There may also be ways to run remote commands other than ssh that would
work better from libvirt, although I don't have any specific suggestion.
