And lguest. I can't tell until I've actually implemented it, but I think it will seriously reduce the need for page pinning which is why only root can currently launch guests. My concern is locking: this is called with the page lock held, and I guess we have to bump the guest out if it's currently running. (Oh, and this means lguest needs to do a reverse mapping somehow, but I'll come up with something).
