You DO know that you can just add a new disk image to domU and add it
to the LVM, right?

I'm guessing virt-resize will copy the data from the old disk to the
new, bigger one.
If so, it'd create I/O load to the disk which might not be desirable
if you have other domUs running.
Adding a second disk to the LVM set has the benefit of:
- doesn't require copying existing data
- can be done live without shutting down domU

Good trick, I didn't know you can do that.
Glad to hear you were able to solve your problem.
