My domU installs are stored in LVM. So when I setup an XM config I will pass a 
single disk

disk = ["phy:/dev/virtvm/ubsvr91,hda,w"  ]

here the Ubuntu installer will take my disk and choose a layout to install 
Server 9.10, which is LVM based. 

Once the install is finished, I find it quite complicated to drill through the 
layout with fdisk, pvs, vgdisplay, lvdisplay, and losetup/kpartx to see all the 
details of the install.

Besides using commercial tools, what can be done to simplify this? Hacking the 
layout is vital for doing backups, restores, or resizing.
