Hi, sorry for late reply,
You can run Ryu controller in two machine/vm/containers (just give them
different IP address) by using
If you don't have multiple machine, you can simply change OpenFlow listen
port, for example:
$ ryu-manager --ofp-tcp-listen-port 6653
$ ryu-manager --ofp-tcp-listen-port 6654
