Thank you for your fast response. I hadn't seen a xen domU config
recipe to do this, but I inferred that the approach using
dd, mkfs.ext3, and an NFS store might get me there.
I was a bit unclear in part because I don't know how the dom0 goes
about knowing that the shared image on both sides is something that
will make the migration happy, whereas with the nfs_root technique,
dom0 is unambiguously notified of the common store.

preferred way on several levels, insofar as a SAN fs wasn't around.
Joe.
