Thanks a lot for your work. I have just tried it.

The good news is that kvm is now able to boot a Hurd system, this what
no the case with kvm-12.

The bad news is that kvm-14 seems to be a lot slower than kvm-12 +
modules from kernel 2.6.20. This is the case with a GNU/kFreeBSD guest.
kvm-12 was about 1.5 time faster than qemu + kqemu. kvm-20 is slower
than qemu without kqemu...

Does anybody have an idea about this performance regression?
