Then consider your question about a large box with many processors.
How about the real environment? Is it the case to provide a 16-way SMP
box, or a 16-way NUMA box? I prefer to the latter. If it's a NUMA box,
dom0 sees physical ACPI table and can be configured as NUMA aware.

This is a model we must support if we are to have domain0 handle other processor-related ACPI activities (e.g., power management). The power information and available settings won't make much sense to the user unless there's an equivalence between VCPUs and PCPUs for domain0.
