I am trying to recover the data located on my guest disk.  This guest
disk is a logical volume in dom0.  The guest disk and the dom0 disk are
managed by LVM each with the same naming convention
(VolGroup00/LogVol0[0-1]).

I am unclear about how I could access a LV on dom0 from a domU VM.  Can
you explain how this would be done?
