In that case, yes you can request a set of processes to be restricted to a specific set of cpus. I am not sure how this will effect performance but I am assuming you are not looking for an overall gain, more like extreme fairness control. Download the openvz patch and towards the beginning there is a few paragraphs on the 2nd level cpu scheduler. This will illustrate how openvz selects a process and decides which physical cpu it gets run on. The final choice is made with the normal scheduler, which is where processor affinity would take effect.
