--- Comment #6 from Tom Stellard <tstellar@gmail.com> ---
I've been playing with this a little more and it seems to be working correctly,
but radeon dynamic power management (dpm) always fails to initialize on the
second guest boot. My questions are:
1. What methods are being used by kvm/qemu/libvirt to reset the GPU on guest
shutdown?
2. Is the problem only cuased by the fact that GPU reset is not implemented
correctly in the radeon driver of are there improvements that are needed in
kvm/qemu/libvirt in order to get this working?
