[$] Private memory for KVM guests

Cloud computing is a wonderful thing; it allows efficient use of computingsystems and makes virtual machines instantly available at the click of amouse or API call. But cloud computing can also be problematic; thesecurity of virtual machines is dependent on the security of thehost system. In most deployed systems, a host computer can dig through itsguests' memory at will; users running guest systems have to just hope thatdoesn't happen. There are a number of solutions to that problem underdevelopment, including thisKVM guest-private memory patch set by Chao Peng andothers, but some open questions remain.
