It's really an unsupported configuration. If you want to limit dom0 vcpus
then dom0_max_vcpus= on Xen command line is the correct way. Specifying
nosmp causes the machine to boot up in a legacy configuration which we do
not test, and is likely to cause mismatches in expectations between dom0 and
Xen. There's no good reason to specify it for general use.
