Hi,
I tried to work out the "Example of the operation of QoS by using
DiffServ" on
https://osrg.github.io/ryu-book/en/html/rest_qos.html
with gui_topology.py (using my own browser side code). When I start the
system with
PYTHONPATH=. ./bin/ryu-manager ryu.app.rest_qos ryu.app.qos_rest_router
ryu.app.rest_conf_switch ryu.app.gui_topology.gui_topology
ryu.app.ofctl_rest
Then all requests for "/stats/..." result 404 error (ofctl worked fine
with the first example). Any idea what goes wrong?
I'm testing the system in virtualbox running ubuntu 16.10 image.
[attached some log output from ryu-manager]
