So in the case it's the root user we care about...

...why do we need to test both here?

Is this simpler?

    def wait_ssh(self, wait_root=False, seconds=600):
        starttime = datetime.datetime.now()
        endtime = starttime + datetime.timedelta(seconds=seconds)

        while datetime.datetime.now() < endtime:
            if wait_root and self.ssh_root("exit 0") == 0:
                guest_up = True
                break
            elif self.ssh("exit 0") == 0:
                guest_up = True
                break
            seconds = (endtime - datetime.datetime.now()).total_seconds()
            logging.debug("%ds before timeout", seconds)
            time.sleep(1)
        if not guest_up:
            raise Exception("Timeout while waiting for guest ssh")
