Where would you suggest to do that? These two ... > and perhaps even add ASSERTs in _hvm_emulate_one() > and handle_pio(). ... sit down the call tree from handle_hvm_io_completion(). Plus internal vs external isn't distinguishable in _hvm_emulate_one() afaict (neither on the way in nor on the way out). Adding ASSERT()s there suggests the distinction would need to be done up the call stack, yet up the call stack may only be the VM exit handler. I don't think the state reset should be done in vendor- specific code.
