I can see how that works using initrd to mount *nbd as root in guest
domains, but what about using *nbd in dom0 and then allocating that as
VDs to the other domains?  Is that supposed to work?  I remember
something about needing physical raw partitions for VBDs, at least under
1.2.  Am I missing something?

(For anyone curious, if using *nbd I would need to keep it in dom0,
rather than in each guest, for both security and maintainability.  For a
public Xenoserver, uid 0 on the guests is assumed to be untrusted.)
