I think it'd be interesting to use DRBD with Remus, since it does a nice job with things like resynchronization which you would need when the primary comes back on line. But DRBD gives your VM one shared block device, so as I mentioned in the the SAN question below, Remus would need some form of journal or transaction layer over the block device to be able to roll back uncommitted writes. A shared-storage option is on our to-do list.
