Although Xen supports SMP machines, each guest OS kernel must be
uniprocessor. Post-2.0 that's something we plan to address, but
for now you'll have to make do with running uni-processor
guestOSes on each CPU.

Ensuring strict protection is maintained while running SMP guests
is actually quite a challenge, but one we've thought pretty hard
about and have some neat solutions ready to implement.
