Isn't this doing (almost) the same as KSM?

(Except that KSM solves the problem much more directly, no?...)

KSM today deduplicates pages between guests and not between guest and host. One of the future TODOs is to look at KSM as well, but dealing with anonymous pages as KSM does today is very different from dealing with anonymous (guest cache as seen by the host) and page cache as seen by the host is not a trivial task.
