Don't even bother creating a project. Just submit the patches back to
QEMU. There's been a lot of discussion about this functionality within
QEMU. There's no reason to fork QEMU yet again (Xen has given up and is
now maintaining a patch queue). In this case, there's no reason why you
would even need a patch queue.
