It's open source, so anybody is welcome to add host support for Linux
or any other OS.  The windows host driver code is intentionally very
portable and will be even more so once we resume work on the MacOS
version.  We try to avoid host-dependent designs but of course also
want to achieve the best performance possible, so we'll probably end
up with a fairly generic base implementation of most interfaces with
some alternative implementations which are optimized for specific host
OS versions.

I don't know enough about KVM to list specific differences, the most
user visible difference is the exact specification of the virtual
hardware, which is identical between Xen and KXen, and eventually the
option to use Xen's paravirtual drivers.
