kpartx should make the partition(s) from the img to be visible to the dom0

if any of the partitions is an PV then you probably need a pvscan/vgscan 
for LVM to pick them up
then you'll probably need to mark the LV active with lvchange -ay

then you can try to mount or fsck it

beware that the /dev/mapper names will usually vary from the device 
names you use in the domU
I tend to use LVM in the dom0, but not in the domU, it makes life 
complicted like this when you come to expanding filesystems, and 
presumably has some sort of (minor) performance hit.
