Is there an easy way in xen to disable a cpu in an smp box? That is, if I have a 2-cpu machine, I want xen to ignore one of them and just ran as if it''s a 1-cpu machine. I could physically remove a cpu, but a software method would be much more convenient.

If one has 8 cpus, and only wants to disable half of them(or 1, or 5, or whatever). ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
