I'm not especially familiar with dd, but couldn't it be used for
this? It seems I recall something about skipping blocks before writing, so
if you skip enough blocks to go to the end of the file and then write enough
blocks to extend it as much as you want, wouldn't this make the single disk
that much bigger the next time it is mounted to a domU? Obviously it would
be wise to back-up the image first, and this would probably be an offline
operation, but it seems to me it might be better (or at least easier to
manage) than having two physical volumes (unless you want to use two real
disks or something).

Hi
hi,
Is there a simple way to expand the image in order to expand the lvm?
kinda:
add another image file as /dev/hdb to your domU, create a physical volume on
the new disc and extend your volume group with vgextend.
hth,
