[James Page]

focal testing:

neutron-ovs-cleanup (on first install from update pocket)

     Active: active (exited) since Wed 2020-07-08 16:36:12 UTC; 32s ago

neutron-ovs-cleanup (after package upgrade to -proposed version)

     Active: active (exited) since Wed 2020-07-08 16:36:12 UTC; 1min 18s
ago

task not restarted as part of the package upgrade.

** Description changed:

  == Impact ==
  
  Upgrades to OpenStack Ussuri will result in service disruption to the
  network datapath for instances and other virtual networking concepts.
  
  == Test Case ==
  
  Standalone
+ apt install neutron-openvswitch-agent
+ (add proposed pocket)
+ apt install neutron-openvswitch-agent
+ neutron-ovs-cleanup unit will be restarted
  
  (UCA)
  add-apt-repository cloud-archive:train
  apt install neutron-openvswitch-agent
  add-apt-repository cloud-archive:ussuri
  apt dist-upgrade
  
  (neutron-ovs-cleanup will be restarted)
  
  Full cloud (UCA or distro)
  Deploy OpenStack Train (using Juju charms)
  Create networking, boot instances and confirm connectivity to instances
  Upgrade to OpenStack Ussuri (using Juju charms)
  Networking to instances will be lost
  
  == Regression Potential ==
  
  Medium - the fix is purely in package and ensures that the
  neutron-*-cleanup scripts are not started on install or restarted during
  an upgrade.
  
  == Original Bug Report ==
  Release: Focal/Bionic+Ussuri:
  
  As part of the package upgrade for neutron-openvswitch-agent, the
  neutron-ovs-cleanup systemd unit is restarted.
  
  This unit should only be run on reboot, and not during package upgrades.
  
  It has the side effect of removing all ports from the local OVS bridge,
  impacting networking to services.
