Hi Team,
I'm trying to learn ryu and followed the ryu documentation for my learning.
I have created 3 hosts, 1 switch and 1 controller using 'sudo mn --topo
single,3 --mac --switch ovsk --controller remote -x'. But when I try to
laucnh ryu-manager from controller, it gets hung as shown in logs below.
Also ovs-dpctl gave some errors.
Can someone check the logs and help me to move forward or debug this issue?
