That's a good question. I am not really familiar with the qcow code but
I think I saw quite some differences. If you put enough effort on it,
you could probably get a single driver for both, but I can't really
estimate if it was a sensible thing to do.

The main reason why I did it this way is that it is the way qemu has
done it, so I just had to take and adapt their code. I'm not sure if it
is a good idea to diverge too much from the qemu code base.
