The example that i gave was a very basic interface for the scheduler, though my ultimate aim
would be to create an interface that would allow sharing at multiple levels, like assigning
40% share for Real-time processes or child process getting its share from the parent.
As far as the fairness of the scheduler is concern, VTRR is achieve pretty good fairness over
a bounded period of time as compared to various other proportional share algorithm. Thanks for
the vkernel example.... :)

I liked the example you gave with the ability to define a percent of the CPU to be used.
If the scheduler can reliably distribute that amount, it would be killer together with vkernels.
Its very very nice in a VM (vkernel) to be able to set up hard network/memory/cpu/disk quotas.
Now all we need is live migration and hot fail-over ;)
