I had downloaded ryu 3.6ova image, and do some necessary action according the
direction on openflow tutorial.
include :
time sudo apt-get install python-eventlet python-routes python-webob
python-paramiko
git pull
so i'm sure my ryu enviroment should be OK.
then i start the ryu controller
PYTHONPATH=. ./bin/ryu-manager ryu/app/simple_switch.py
and start mininet
sudo mn --topo single,3 --mac --switch ovsk --controller remote
till now , everything seems fine, and i can set up flows in ovs.
but when i want to use topology view, i met some problem,
i use the command
PYTHONPATH=. ./bin/ryu run --observe-links ryu/app/gui_topology/gui_topology.py
but it seems not work well.
please see the dump info:
