I want to benchmark the box using one or two CPUs, with and without hyperthreading, as listed in the configurations above. To do this I want to use the boot options also listed in the original post above. I can reboot the box remotely but I can't physically remove a cpu to get the single cpu+ht config, so I'm looking for boot line options to provide that.

I'm not trying to manage the power, it's not a laptop, I'm trying to run benchmarks as noted in the first sentence of my question. I don't see how you got from there to virtualization from how to start (or not) cpus.
