I know a good way to make a process make the most of the hardware and play cooperatively with other processes: don't use virtualization.
I will never understand the whole virtual machine and cloud craze. Your operating system is better than any hypervisor at sharing resources efficiently.

After reading the README of virtualization tools (and looking at the author) I discovered the benefits of using them. I recommend also giving that a try.
