Steven,

I think I understand what you are saying but let me try to summarize.

You would like the ability for an administrator to access LVs on an embedded
domU image file, so you can get at the data on there without having to boot the
domU (which may not even be possible in some cases).  I in fact ran into this
recently as well when an install of rawhide on a domU failed to install grub
properly.  I was able to work around this by using a procedure similar to this:
http://wiki.xensource.com/xenwiki/InstallGuestImage
and by renaming the volume group.  As I recall I hit the bug of the device file
not getting properly updated on the rename, and I will check the latest code for
the bug in comment #1.  Did I summarize the original problem correctly?

Will think about ways to improve the situation so maintenance of xen domU images
are simpler with LVM tools.  Not sure what the answer is - might go beyond LVM
tool enhancement.
