Unlike Xen, the host isn't a special sort of guest. The host is the host, and so you just use standard Linux techniques. The way I know to do this is to add "isolcpus=..." on the Linux boot command line, although I've not used this for quite a long time and I haven't tried it on RHEL 6. isolcpus works in reverse: it's the CPUs that you want Linux *not* to run on, so you probably want something like isolcpus=1-3 Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
