I found file named openvswitch-agent.log in both compute and network and they're just empty, the line you said is present in Neutron.conf

I do face the same issue, The above resolution didn't work for me. I get the same issue again.... :(

I use Centos 6.4 version, and Controller, Neutron server and compute nodes running on VM.

uses qemu as hypervisor
