[Openstack] [Kilo] No OpenFlow Rules generated on network node

Hi Andreas,

i managed to have them created by deleting the network and recreating it (using neutron command line). 

Maybe i had something not setup correctly when i first created the network or somethin went wrong back then. 

Nevertheless, it works now. 

Thanks for offering your help!

Hi Thomas,
could you please share your neutron-server and neutron-openvswitch-agent configuration files?

Did you set debug to true in your configuration and restarted the neutron-openvswitch-agent on your controller node?

But the tunnel interface is created correctly, so that the compute node is able to send traffic to the network node (which is then discarded).
