Do control groups prevent the host from using those CPUs? I want only the VM to use the CPUs, and dont want any host user or kernel threads to run on that physical CPU. I looked up control groups, maybe I missed something there. I will go back and take a look. If you can clarify, I would appreciate it:) > >> > 3.

Its more of an investigation at this point to understand what can happen.. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
