The beauty of KVM is that there's no need to actually implement
this for KVM. It can just use all the infrastructure of standard
Linux that is available for this.
The hierarchical group scheduler and "memory cgroup" work that is being
worked on in recent kernels should be able to do i) and ii). Partly
it could be also done using older technology like cpusets or
numa emulation or nice levels.
