I think we should add topology discovery hypercalls. Xen needs to know this
stuff anyway, so we just provide a mechanism for guests to extract it. An
alternative is to start exporting virtual ACPI tables to PV guests.
I will look at this next. The HVM approach seemed to be easier from my POV, but this NUMA propagation is also benefical for PV guests. Maybe one should solve the whole NUMA-ballooning issue while looking at this.

Regards,
Andre.
