Do you mean you want to temporarily mount the domU's disk (LV) on the
dom0 while the domU is stopped? In which case, look at "kpartx" which
can create /dev/mapper devices for each partition within the LV

You can stack LVs if you happen to use LVM inside the domU too but
you'll need to do a "vgscan" and "vgchange -ay" to find and activate
the nested VG after the device is created for it before you can access
the LVs within it.

Or perhaps you mean something different?
