Hi Fujimoto san,
Thank you for the information.
To add the port, I didn't use "run_command()" in bridge.py. To be honest, I
didn,t know yet how to use it :). However, to add the port, I was trying to
add function (add_port) in bridge.py. The function is very similar to the
del_port function. It was working, the port was added in remote OVS. Btw, I
was wondering whether it is OK to do add-port, add bridge, del-bridge
through this way? (by adding function in library bridge.py).
My second question, when I ran the app, I got this message. Would you mind
to let me know whats is the problem?
