I think we should explore this a bit more. AFAIK, we can simulate a NUMA
system with CONFIG_NUMA_EMU=y and providing numa=fake=XXX to the guest
kernel. From a quick check with some RAX folks, we should have enough
control to arrange this. Since we can put a custom kernel (and
parameters) into our GRUB configuration that pygrub should honor, I
would think we could get a fake-NUMA guest running in at least one
public cloud. Since HP's cloud runs KVM, I would assume we have control
over our kernel and boot there as well.

Is there something I'm missing about why that's not doable?
