Then it sounds like a bug, if the system is idle while process/domain are trying to push data on that very system and blocked on processing this sounds like an I/O scheduling error or something is blocking in your test. An interesting point would be to test with virtIO between 2 domains hosted on the same machine, to make sure it's not the actual networking access which is the limiting factor, and would provide an interesting data point.
