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? --Dan
