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, Ingo
