Summary: Need ability to handle duplicate VG names for Xen

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.
