Oh, we are just ignorantly blundering around trying to find a good 
solution! :-)

We are not trying to reimplement the wheel (at all), if you check we 
started with VNC GUI support which is as far from NIH as it gets! :-)

I didn't know about QXL but it looks interesting at first sight: a 
virtual GPU seen by the guest OS with Xorg support for it in the 
guest Xorg. But i do not see guest kernel framebuffer support for it 
- how does that aspect work, if one boots without Xorg, etc.?

Thanks,
