Bug Description

In an OSA-deployed Pike environment specifying the openvswitch ml2 driver, openvswitch's run path (/var/run/openvswitch) is not created by OSA. As a result, the openvswitch database service, ovsdb-server, fails to start up, and openvswitch is non-functional.

From /var/log/messages:
Mar 6 18:30:22 pike06-neutron-agents-container-af2bf6c5 ovs-vsctl: ovs|00002|db_ctl_base|ERR|unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory)

Creating the directory manually allows ovsdb-server to be successfully restarted. OSA should create this path during deployment so that ovsdb-server can start without manual intervention.

I have reverted the fix because we shouldn't have to create these directories ourselves. Open vSwitch is able to create these directories before starting the services so what you report here is probably a missing backport of

https://review.openstack.org/#/c/556892/

If this still doesn't fix the issue, it's a distribution packaging problem. OSA is not different than a 'user' in this case, so users are not expected to create /var/run/openvswitch themselves before installing ovs.
