Are you really guaranteeing full POSIX semantics for all these calls? And not say, POSIX-like except where Linux decides to differ because POSIX is dumb? How is the guest (which expects the semantics of its own OS) going to know that connect(2) to an external IP is going to behave differently to say connect(2) to localhost? Given: a) The difficulties in reconciling the differences in behaviour and features between remoted system calls and local ones. b) The difficulty in fully specifying (and thus fully implementing) the PV interface. c) My belief that most of the advantages of this proposal can be achieved with smarts in the backend. I'm not sure there is much merit in discussing the finer points of the protocol until these bigger architectural issues have been addressed.
