  ISTR this being the case, too, from past installations on file-backed
'tap:aio' domUs, but I don't haven't tried installing that way this time
(fdisk output from domU and dom0 at end of this message).  I'll try
installing to a file-backed domU early next week to see if that behaves
as expected.

  Is the domU configuration below correct for domU to see
a "whole drive"?  Is there anything special that needs to be done to the
LV (/dev/vg0/xen-3-root) in dom0 for this to behave correctly?  I've
tried pretty much everything from zeroing out the LV to creating one
large fdisk partition before installation.

  root = 'xbd0d' # also tried xbd0, xbd0a...doesn't seem to make a diff.
  disk = [ 'phy:/dev/vg0/xen-3-root,hda,w' ]

cheers!
