Will need to see your current XML to tell. But if you simply copied
and pasted my code, then it's definitely not going to work. For one
thing, you would need to have created a LVM volume named exactly the
same way I did.

If you simply changed the paremeters using your existing .img file as
the source, then it also won't work simply for obvious reasons.
