Re: [Xen-devel] PV-vNUMA issue: topology is misinterpreted by the guest

This thread has gotten a bit long...

For Linux I would like to see:

1. No support for NUMA in PV guests -- if you want new MM features in a
guest use HVM.

2. For HVM guests, use the existing hardware interfaces to present NUMA
topology.  i.e., CPUID, ACPI tables etc.  This will work for both kernel
and userspace and both will see the same topology.

This also has the advantage that any hypervisor/toolstack work will also
be applicable to other guests (e.g., Windows).
