And it works when I start two guests and bind tcp port to guest serial port, but it is really slow. And if I use -serial /dev/ttyS1 for the guest debugging target, I can't talk to it from my dev machine that has connected to ttyS1 with target machine (host). Is this a known problem? Thanks, Neo -- I would remember that if researchers were not ambitious probably today we haven't the technology we are using!
