Agenda

On Demand agenda. Use this section to add your proposal to this meeting; do not use any other section (keep this template, please):
- (irc nick): topic
- (ralonsoh 2026-01-09) [RFE] OVN wait for ovn-controller at live migration (https://bugs.launchpad.net/neutron/+bug/2069718)
  - Nova (os-vif) will be able to create the TAP device before libvirt (https://review.opendev.org/c/openstack/os-vif/+/971231).
  - Neutron will wait for the `Port_Binding.additional_chassis` in order to send the vif-plugged event (https://review.opendev.org/c/openstack/neutron/+/956910).
  - Neutron will have a static configurable variable to set a flag in `vif_details`, that will be read by os-vif. This feature can be enabled/disabled with this Neutron flag.
  - Future work: core OVN to inform when the OF rules have been written in the local OVS. At this point, the TAP device is able to communicate.

 ** (irc nick): topic
-** (ralonsoh 2025-11-21) Refactor neutron-keepalived-state-change (LP#1970944):
+** (ralonsoh 2026-01-09) [RFE] OVN wait for ovn-controller at live migration (https://bugs.launchpad.net/neutron/+bug/2069718)
-*** keepalived notify scripts replacement: https://review.opendev.org/c/openstack/neutron/+/125384. Cause: two consecutive quick events (transitions) could report an incorrect state.
+*** Nova (os-vif) will be able to create the TAP device before libvirt (https://review.opendev.org/c/openstack/os-vif/+/971231).
-*** This issue was still present with this implementation and fixed (or at least highly mitigated) by https://review.opendev.org/q/I70037da9cdd0f8448e0af8dd96b4e3f5de5728ad
+*** Neutron will wait for the `Port_Binding.additional_chassis` in order to send the vif-plugged event (https://review.opendev.org/c/openstack/neutron/+/956910).
-*** My proposal: to have a configurable state report method (python script, notify scripts) during some releases. Make the current one (python script) the default one but change it in the next release. If the new method (notify scripts) is reliable, remove the python script implementation.
+*** Neutron will have a static configurable variable to set a flag in `vif_details`, that will be read by os-vif. This feature can be enabled/disabled with this Neutron flag.
-*** POC: https://review.opendev.org/c/openstack/neutron/+/965909
+*** Future work: core OVN to inform when the OF rules have been written in the local OVS. At this point, the TAP device is able to communicate.
-*** NOTE: I need someone else to implement this feature, I won't have time for it.
-*** NOTE: haleyb to send request to ML and/or Liu for his input
