Hello

I have 4 core processor, and i would like to use processor0 for my system processes.
I configured vmware to use processor1 for vmware_machine1 and processor2 for vmware_processor2.

How can i control which process is run on which processor ?
How can i control in gentoo which processor should we user for all typical system processes ?

Thanx

as I know, affinity only apply to hw interrupts, eg: sys-apps/irqbalance

But - how do vmware selects which process (virtual machine) works on which processor ?

For me the perfect situation is:
- all system processes use processor 0
- some system processes user other processor (virtual machines)

i really don't know, but i could imagine that vmware uses exactly this.
