Comment 5 for bug 1910209

Christian, thank you so much for quickly replying, but in Ubuntu 16.04, /var/run/openvswitch wasn't removed after "systemctl stop openvswitch-switch", in Ubuntu 18.04, ovs deamon also doesn't remove /var/run/openvswitch, can you tell me who created /var/run/openvswitch and who removed it? I just want to let it work normally.

For dpdkvhostuserclient case, this unix socket /var/run/openvswitch/vhostuser/vhu* is created by qemu once, ovs DPDK won't create it when it is restarted, this isn't ovs DPDK's mistake, it should be so. Right now, it is removed by "systemctl stop openvswitch-switch", this is root cause it can't work.
