If the dhcp-agent machine restarts when openvswitch comes up it logs the following warning messages for all tap interfaces that do not exist: bridge|WARN|could not open network device tap2cf7dbad-9d (No such device) Once the dhcp-agent starts it recreates the interfaces and re-adds them to the ovs-bridge. Unfortunately, ovs does not reinitialize the interfaces as they are already in ovsdb and does not assign them a ofport number. This situation corrects itself though the next time a port is added to the ovs-bridge which is why no one has probably noticed this issue till now. In order to correct this we should first remove interface that exist and then readd them. Closes-bug: #1268762 Change-Id: I4bb0019135ab7fa7cdfa6d5db3bff6eafe22fc85
