Probably true for those with new Intel VT-enabled processors. I will be 
getting an  AMD processor which has Pacifica, which is not identical in 
features to  Intel's VT. So I have doubts about running OpenBSD in virtual 
mode on  AMD64-Pacifica unless specific support for Pacifica is present in Xen.

I expect to run an *unmodified* OpenBSD using Xen's hardware support for 
virtualization via Pacifica. I hope I am not living in airborne castles!

You are not alone! And not just about Xen either! I ignore it.

I think the OpenBSD developers are focused upon server enhancements.
I think they will get much more interested in Xen if they see a use for
it in OpenBSD server operations.

I will have a very strong incentive to get OpenBSD running on Xen when I
finally have both a Pacifica-enabled AMD64 system and a copy of the source
tree of Xen with Pacifica support.
