Linux Ingo Molnar released a new patchset titled the 'Modular Scheduler Core and Completely Fair Scheduler'. He explained, "this project is a complete rewrite of the Linux task scheduler. My goal is to address various feature requests and to fix deficiencies in the vanilla scheduler that were suggested/found in the past few years, both for desktop scheduling and for server scheduling workloads."

I am by no means an expert on any of this, but my guess would be that if a schedular is completely fair, then virtualization wouldn't be too good off, as the virtualized box would get one tick / whatever, no exceptions. All the processes in that box would have to run off that one tick (basically).

Of course, I could be completely wrong, in that case ignore me.

When they say "Completely fair", they actually mean more fair than equal. The processor time is divided in a fair way so that latency sensitive apps can be prioritised over more throughput apps. What you have described is equal timeslices (except nobody divides it as small as single ticks) which can be used on the current kernel, I believe.
