Newbie question on Xen3 with NetBSD4Beta2

I'm trying to setup Xen 3 with NetBSD 4.0 Beta2 on an Athlon
64 X2 machine.

XEN3_DOM0 seems not configured with options MULTIPROCESSOR,
and when I
tried it, it fails to compile.  Is it supposed to be so?

With XEN3_DOM0 kernel and a single XEN3_DOMU domainU, CPU
is
noticeably hotter than with non-Xen kernel, according to
onboard
temperature sensor.  In fact even when 100% idle state, it
is close to
100% load of non-Xen kernel.  Is it normal?

When I configured azalia(4) driver with XEN3_DOM0, it
crashed when
booting-up.  Should I send-pr?  Also, configuring fdc(4)
with acpi
failed to link.

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.
