Even with your fragmentation avoidance and memory defragmentation, there are still going to be cases where memory does get fragmented and can't be defragmented. This is Ingo's point, I believe. Isn't the solution for your hypervisor problem to dish out pages of the same size that are used by the virtual machines. Doesn't this provide you with a nice, 100% solution that doesn't add complexity where it isn't needed? -- SUSE Labs, Novell Inc.
