Yes, MULTIPROCESSOR is not supported by NetBSD/xen yet. This just means you
can't use both CPU in a single domain; xen itself is SMP, and if you have
several domains they will spread across all CPUs.

what does 'xm top' says ? It's possible that the xen.gz kernel isn't using
power management options to stop the CPU when idle, but instead use
a spin loop waiting for something to do.

Yes, please.
