To do this cleanly, enlarge one of the qcow2 files to an appropriate size,
then mount both in a VM, and rsync the contents to the enlarged disk.
Assuming there are no collisions, you should be fine.

Resize the image with qemu-img resize image.qcow2 +SIZE. where SIZE is the
size (e.g. 10G for 10 gibibytes). Do that from the KVM server when the
qcow2 is either unmounted, preferably with the VM in question off.
