Do you follow multi-node architecture? I have one compute node, one controller node and one network node. I ran "ovs-vsctl --may-exist add-br br-int" in Compute and Network node. br-int is required for VMs to communicate with br-ex and to the external world.

You need to add br-int by hand.

I have already add ` root@network:/var/log/neutron# ovs-vsctl list-br br-ex br-int

yes.. i believe you better check if br-int is listed inside the bridge or not.
