ovsdb events not firing. #157
Description
I'm trying to use the qos_rest example in the repo. I cannot manage to create a queue because of this response:
[
{
"switch_id": "0000000c298b1415",
"command_result": {
"result": "failure",
"details": "ovs_bridge is not exists"
}
}
]
By looking at the code i think there is a problem related to ovsdb
I have already tried the simple switch example, without any problem, but the real issue for me is that the handlers for ovsdb related events are never fired.
One thing i know for sure is that it's not a connection problem, my switched can reach the controller/manager.
Using the example written here ( Link from the Ryu docs ), i can clearly see the connection in the log ( using ryu-manager --verbose ) but the following exception occour:
root@controller# ryu-manager test_ovsdb.py --verbose
loading app test_ovsdb.py
