Currently we are only able to bind the whole domain to some host nodes using the /domain/numatune/memory element. Numerous requests were made to support host<->guest numa node bindings, so this series tries to pinch an idea on how to do that using /domain/numatune/memnode elements. That is incompatible with automatic numa placement (numad) since that makes no sense. Also this disables any live changes to numa parameters (the /domain/numatune/memory settings) since we cannot change the settings given to qemu.
