And just allow me to clarify that this has nothing to do with NUMA node
affinity, neither with the specification, nor with the behavior...
I am working on per-vcpu node affinity (among all the other NUMA stuff,
of course), and I will submit it soon... It just is not this, ok? :-D
Here, I'm just introducing a new, and possibly more comfortable, way of
specifying vCPU to pCPU _pinning_.
Regards,
Dario
