Comment 10 for bug 1496135

I thought this might have been resolved in Train with this blueprint:

But that doesn't support the case of an instance with a vcpu pin set without a NUMA topology. Artom at one point had that mostly fixed in that series but it was complicating things very close to feature freeze so it was removed, but could probably be easily added back in as a fix in the Ussuri release.
