They've apparently got Windows ported to it; they just can't release
it owing to the license. They've got NetBSD too.
The research group I'm in is currently looking at Xen because it
should make a pretty nice environment for developing an OS: it
provides standard virtual devices, so we can just write one set of
network/video/disk drivers and still get reasonable performance, and
we can run it at effectively native speed alongside Linux on our
They've got some cool-looking image migration stuff too (a colleague
described moving a Linux system playing video between PCs without
noticable interruption). Yes, it's definitely cheating, but it's
pretty non-intrusive cheating, and the result is actually useful...
