Hey, I wrote the stuff for http://grml.org/qemu/ ;)

Just press ctrl-alt-2 *inside* running qemu and use 'info kqemu' then.
What does it return?

Sorry, I've never used a qcow overlay image on my own. Maybe someone
else on this list has experience in using it and can write some
words about it?

Excellent idea, thanks - will be implemented soon, you can track it
