Waht reports /var/log/neutron/ovs-agent.log ?
Are there a lines in neutron.conf :
[AGENT]
root_helper = sudo neutron-rootwrap /etc/neutron/rootwrap.conf

Hi,

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

How looks on your Compute Node
