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. > ia32 is utter crap with respect to power management, virtualization, > and generalized firmware. > > If you don't have remote power management, buy it in whatever form > possible. 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. -- bill davidsen CTO, TMR Associates, Inc Doing interesting things with little computers since 1979. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
