No need to apologize. You've been entirely courteous and professional. > But, with hundreds of guests, a few small points of overhead may add up. Absolutely. Going back to my original point, that shared/virtualized environments are different in this regard, the Open Source Xen project is trying to learn as much as possible about how VM, and now z/VM has dealt with these sorts of issues over the decades. Unlike a lot of people who think there's nothing to learn from the mainframe world, they're very eager to avoid as many well understood problems as possible. Our experience with Linux on z/VM has been invaluable to them, as well as the "user mode Linux" folks, such as wanting to get rid of the 100Hz (now 1000Hz) timer interrupts that would chew up and entire CP/IFL with enough guests running. :) They're hitting the same sorts of problems, and actually looking to us to help them out.
