So far I'm really wondering. Basically you have virtualization specific scheduling only if the virtualization mechanism has its own scheduler and that's only the case for Xen at the moment unless I'm mistaken. All others reuse the scheduler of the primary Os directly, and unless you start playing with that scheduler there is nothing really to tune, but those changes affects far more than just purely the virtualization side. How would you map the API you propose with say the linux normal scheduler APIs ? I'm a bit worried if the proposed operations are really only making sense in a setup with the Xen hypervisor.
