Put the image file on a loop device, then activate the volume group it
contains:
losetup /dev/loop0 my_file.img
vgscan
vgchange -ay <vg name>
Then you should be able to access it as normal. Just dd the file system
off the LV device node.
To shut it down:
vgchange -an <vg name>
losetup -d /dev/loop0
Obviously, change loop0 to something else if 0 is already in use.
Kind regards,
Bryn.
