A related question--it seems that the xen hypervisor kernel (as shipped with redhat) doesn't recognize
any NUMA structure that the machine may have.  so if you pin, which
we do sometimes, how to ensure that you get memory bank closest to your cpu?

Back when we were first setting up our xen systems, it was recommended practice to pin the cpu's on your DomUs instead of allowing xen to manage them.

Is this still the suggested practice?
