Doc Type: Bug Fix
Doc Text:
Before this update, `openstack overcloud deploy` did not pass the value of the `OVNAvailabilityZone` role parameter to OVS. + With this update, the `OVNAvailabilityZone` role parameter correctly passes the value as an `availability-zones` value in `external-ids:ovn-cms-options`. + The following example shows how to use the parameter in an environment file to set `OVNAvailabilityZone. Include the environment file in the deployment command. + ---- ControllerParameters: OVNAvailabilityZone: 'az1' ---- + The deployment adds `availability-zones=az1` to OVS `external-ids:ovn-cms-options`.

Description Spoorthi K 2023-08-17 11:43:23 UTC 
Description of problem:
On 17.0 with "OVNAvailabilityZone: '<availability_zone_value>'" on controller, the OVS configuration doesn't show up the configured values. 

Version-Release number of selected component (if applicable):
Tried on 17.0 and OVNAvailabilityZone didn't seem to work.

How reproducible:
Always

Steps to Reproduce:
1. Create a overcloud environment file. Eg:
parameter_defaults:
  NeutronDefaultAvailabilityZones: 'az-datacenter2,az-datacenter1'
  ControllerParameters:
    OVNCMSOptions: 'enable-chassis-as-gw'
    OVNAvailabilityZone: 'az-datacenter2,az-datacenter1'
2. Trigger overcloud deployment with this environment file.
3. Check the ovn-cms-options in OVS external_ids using "ovs-vsctl get o . external_ids" in controller.

Actual results:
[root@controller-0 ~]# ovs-vsctl get o . external_ids
{hostname=controller-0.localdomain, ovn-bridge=br-int, ovn-bridge-mappings="datacentre:br-ex", ovn-chassis-mac-mappings="datacentre:fa:16:3e:d8:ae:ad", ovn-cms-options=enable-chassis-as-gw, ovn-encap-ip="172.16.4.76", ovn-encap-type=geneve, ovn-match-northd-version="true", ovn-monitor-all="true", ovn-openflow-probe-interval="60", ovn-remote="tcp:172.16.2.110:6642", ovn-remote-probe-interval="60000", rundir="/var/run/openvswitch", system-id="a8fb17f9-11d8-4eba-9efa-ebcb5fc3ea0d"}


Expected results: 
Setting the parameter using "ovs-vsctl set Open_vSwitch . external-ids:ovn-cms-options="enable-chassis-as-gw,availability-zones=az-datacenter2:az-datacenter1" works.

[root@controller-0 ~]# ovs-vsctl get o . external_ids
{hostname=controller-0.localdomain, ovn-bridge=br-int, ovn-bridge-mappings="datacentre:br-ex", ovn-chassis-mac-mappings="datacentre:fa:16:3e:d8:ae:ad", ovn-cms-options=enable-chassis-as-gw,availability-zones=az-datacenter2:az-datacenter1, ovn-encap-ip="172.16.4.76", ovn-encap-type=geneve, ovn-match-northd-version="true", ovn-monitor-all="true", ovn-openflow-probe-interval="60", ovn-remote="tcp:172.16.2.110:6642", ovn-remote-probe-interval="60000", rundir="/var/run/openvswitch", system-id="a8fb17f9-11d8-4eba-9efa-ebcb5fc3ea0d"}
