19.6.0 ^^^^^^
Known Issues ************
* Until the OVN bug (https://bugzilla.redhat.com/show_bug.cgi?id=2162756) is fixed, setting the "reside-on-redirect-chassis" to true for the logical router port associated to vlan provider network is needed. This workaround makes the traffic centrallized, but not tunneled, through the node with the gateway port, thus avoiding MTU issues.
Bug Fixes *********
* [bug 2003455 (https://bugs.launchpad.net/neutron/+bug/2003455)] It is added an extra checking to ensure the "reside-on-redirect- chassis" is set to true for the logical router port associated to vlan provider network despite having the "ovn_distributed_floating_ip" enabled or not. This is needed as there is an OVN bug (https://bugzilla.redhat.com/show_bug.cgi?id=2162756) making it not work as expected. Until that is fixed, we need these workaround that makes the traffic centrallized, but not tunneled, through the node with the gateway port, thus avoiding MTU issues.
* Normalise OVN agent heartbeat timestamp format to match other agent types. This fixes parsing of "GET /v2.0/agents" for some clients, such as gophercloud.
* Neutron can record full connection using log-related feature introduced in OVN 21.12. For more info see *bug LP#https://bugs.launchpad.net/neutron/+bug/2003706*
Other Notes ***********
* The OVN migration performs validation by default. This validation means an instance is spawned and is tested by simple ping after the migration is finished. Also it tries to create new workload post migration. This is useful for very simple scenarios when migration is tested but is not really useful in production since likely the production envrionments already have running workloads. It makes more sense to require the validation explicitly rather than implicitly run it as the migration is mostly intended for production. The VALIDATE_MIGRATION now defaults to False and needs to be changed to True if validation upon request.
