So at this point you have resized the image and told the kernel about
it, you're done with the virt-specific part. The rest should be the same
as on physical hardware.

A quick search on the net suggests indeed that you can't modify a
partition that is mounted/in use by LVM. So I'm afraid a new partition
that is added to the VG must be good enough.
