  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.
