Public bug reported:

I used ocata version neutron and ovs-dpdk with vhost-user-client mode. When I restart ovs, I found the vhost-user-client socket file disappear and 'vhuc' interface link_state is down。
The vhostuser_socket_dir in /etc/neutron/plugins/ml2/openvswitch_agent.ini was set as default value: /var/run/openvswitch. And I found ovs would recreate this directory. As a result, the socket file would be deleted. So I think the default value of vhostuser_socket_dir is not appropriate.
