Title:
  ovs-vsctl add-port hang

Status in OpenStack neutron-openvswitch charm:
  Invalid
Status in openvswitch package in Ubuntu:
  Expired

Bug description:
  Trying to add several ports in my network configuration it seems that
  on the majority of my servers hangs on neutron-openvswitch
  reconfiguration. The unit reports (forever):

  neutron-openvswitch/9   maintenance  executing           172.16.1.247
  (config-changed) Configuring ovs

  The unit logs last lines are:
  2019-01-31 10:42:55 INFO juju-log Creating bridge br-ex-515
  2019-01-31 10:42:55 DEBUG juju-log Interface bond0.515 is not a Linux bridge
  2019-01-31 10:42:55 INFO juju-log Adding port bond0.515 to bridge br-ex-515

  and there is a running process 
  ovs-vsctl -- --may-exist add-port br-ex-516 bond0.516

  
  At the same time, the bridge is successfully created (confirmed with ovs-vsctl show) and networking seems to work fine. 

  As a temporary workaround, I kill the process and allow the charm to
  reconfigure and it passes through this point (sometimes hangs on
  another port) but eventually it completes successfully.

  Definitely the hang of ovs-vsctl is not a charm issue but maybe the
  charm could handle more efficiently such cases.
