The console awaits its output handler, but both sample BMCs supplied a plain function, and both dropped the send_data coroutine. virshbmc additionally receives its stream callback on a libvirt thread, so the send goes through run_coroutine_threadsafe against the loop captured at activation, called asyncloop because the class already has a loop method it uses as a thread target. ServerConsole asked the session layer to retry, which a ServerSession cannot do: it never runs Session.__init__, so it has no timeout, and its _timedout does nothing. IpmiServer.logout was synchronous and an argument short while _cleanup awaits logout(False). The boot options handler answered, then read an unbound name and answered again with 0xff.
