Other domains may have memory allocated, but only actually be using 1/4 of it. In cases like this it would make sense to let the new domain"borrow" the memory. As mentioned above, if the domain who waspreviously was not using all of it's memory suddenly does want to use itthere should be a method to swap pages out. First, we support swap in all the domains, including Domain 0. In this aspect, XenoLInux is the same as conventional Linux. Second, we don't want a domain to borrow memory from others. Every domain has a guaranteed number of physical memory pages. All the resources reserved for a domain will be accounted and paid for by the customer who uses XenoServer. It's irrelevant that when a new domain is started, other domains' performances have to downgrade. You may want to go to http://www.cl.cam.ac.uk/Research/SRG/netos/xeno/ to see the goal of Xen and XenoServer. -- Bin ------------------------------------------------------- This SF.
