Problem Statement: Kolla Ansible installation fails on "deploy" play with the below errors ('Errors' Section).
About the Deployment:
- Lab Openstack deployment using Kolla Ansible
- 1 Controller, 2 Compute nodes, 1 Block Storage node using LVM / Cinder Volumes
- All nodes running Ubuntu 22.04
- "Bootstrap-servers" and "prechecks" plays succeed. The Deploy fails
Troubleshooting done:
- https://lists.openstack.org/pipermail/openstack-discuss/2022-September/030641.html
- This link seems to match my exact issue.
- However, I'm not trying to do SSL on HA Proxy.
- Deployment fails with the same error irrespective of whether "enable_haproxy" is kept on or off.
- Deployment fails with the same error irrespective of whether the "external fqdn" and "external vip" are commented or not / commented.
- My globals.yml output below.

UPDATE 1 - 8th May 4 PM IST:
- I re-built this deployment from scratch.
- The previous deployment was on VirtualBox - switched over to ESXi 8.x (should not make a difference - still pointing it out)
- Increased specs of the VMs being used
- This time i used "rocky" as the "base distro" in "globals.yml".
- Some more changes to my globals.yml (below)
- This time the deployment DID NOT fail on nova-compute services failing to register. However, it broken on a different error message:

UPDATE 1 - 8th May 5:30 PM:
- I believe this is resolved now.
- Changed "base distro" back to Ubuntu
- Changed enable_cinder_backend_iscsi back to "yes"
- The biggest change i made was changing the release from "master" to "zed".
