Latest Attempt at GENODE on NOVA

[Lonnie Cumberland]

Hi Norman,

After some testing, I am coming to the belief that the mouse cursor is
actually within the Qemu window, but is just zooming off the screen very
rapidly when I move the mouse even a little.

Still trying to look at things in more detail though.

Thanks,
Lonnie
