Well, if I had thought a bit longer before replying I would have noticed
that this solution wouldn't really solve driver problem at all. Virtio and
Xen PV provide standardized, paravirtualized devices, but only in areas
that are relevant in server environments. Network interface or random
number generator - no problem. Webcam - that would be tricky. So, trying to
follow the recent trend and creating yet another library OS would cause
serious problem with supporting devices that are important for desktop OS
and make it even harder to achieve good performance.
