Bug description:
== Impact ==
Upgrades to OpenStack Ussuri will result in service disruption to the
network datapath for instances and other virtual networking concepts.
== Test Case ==
Standalone
(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.
