[Fedora-xen] Accessing data on a xen guest disk image

I name my VMs with VolGrp/LogVol, then I have 1 test/rescue VM that I 
create using VolGroup/LogVol. Just having that 1 VM with a different 
naming convention allows me to present any other VMs disks to my 
test/rescue VM and mount them for repairs, recoveries, etc.
