Can you show me your "/etc/ryu/ryu.conf" and all output of ryu-manager?

There are many kind of the problem, I think that there is not the simple way.
For example...
- watching ryu-manager's log
- confirm a connection with OVS
$ sudo ovs-vsctl show
fd908bb0-dd7e-45f5-9a01-78456d88510d
Manager "ptcp:6634"
Bridge br-int
Controller "tcp:192.168.122.60:6633"
is_connected: true
...
- confirm a flow table
$ sudo ovs-ofctl dump-flows br-int

I suggests trying devstack with ryu-plugin until you get familiar with Ryu.
