Who does not? ;)

Yes, I certainly believe that the NetBSD-kernel is the place porters
will look at (first). IIRC, OpenBSD changed some parts, but they are
still very close imho. 


I have basicly no real experience in porting a kernel, neither do I know
much about NetBSD/OpenBSD in great detail, however I am very interested
to see OpenBSD in dom0/domU. Interested enough in trying it ;-)

However, I suggest to wait till xen3.0 has been released, simply to be
sure that the API/ABI does not change anymore. This is at least what I
heared.

I am unsure if you can reduce it to this. I certainly never trusted
Linux, nor do I want to make Linux access my Hardware. Just my 2 cents,
if anybody wants to start a flamewar about this, please change to topic
so my spam-filter can be configured to catch them correctly.
