I'm not sure you really want to base on the Beagle emulation for OpenQA.
The "virt" machine in QEMU would make a much nicer target, especially
since it also supports KVM properly. The only missing link to get
everything properly running is a working virtual PCI host bridge so that
we can use PCI VGA adapters and USB for keyboard/mouse.
Writing such an emulation is on my todo list, but I'd be more than happy
if someone else beats me to it ;).
However, as for your original question:
Peter, did I ever send you the patch above?
Alex
