Perhaps one way to address this problem would be to make the Dom0
interface less intrusive for the host OS?

Maybe impression last time I looked was that there was huge potential
of improvement in this area. For example the PAT issue
recently discussed was completely unnecessary.  Or if you
added a "VT/SVM only" Dom0 mode I'm sure the interface
would be significantly cleaner too. If you can come up
with a slim clean interface the chances for actual integration
would be likely much higher.

And if people want to update the Dom0 they surely could update the
hypervisor to one with cleaner interfaces too.

I understand that the DomU Xen ABI is becoming a kind of standard
and should be supported, but that's far from true for Dom0.
