That's entirely different issue, -- inability to debug windows guests. Please don't hijack other threads for unrelated issues -- it makes finding information and replying more difficult. If it does not work for you, ask in a new thread. But before, try to research the issue a bit, I've seen several discussions about debugging guests over serial port in kvm. Besides, I've no idea what are you really trying to do - debugging a guest is much easier in kvm than to set up another HOST and connect two HOSTS over a null-modem serial cable.... /mjt
