Bug Description

**Bug Report**

What happened |
I deployed Single-Node OpenStack(Yoga) using kolla-ansible(14.8.1.dev66). Deployment fails on the step where Nova is registering compute nodes. Upon investigation, I found that all the services that need to connect to rabbitmq their containers keep restarting restarting.

All service logs are prompting the following error:
      "Unhandled error: OSError: Server unexpectedly closed connection"

The reason for this issue is that the RabbitMQ queues are not present for services like cinder, nova, neutron and heat.

What you expected to happen |
Queues should be created for all enabled services and deployment should be successful.

How to reproduce it |
Follow this documentation:

* OS = Ubuntu-22.04
* Kernel = Linux openstack 5.4.0-99-generic #112-Ubuntu SMP Thu Feb 3 13:50:55 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
* Docker version = 24.0.2, build cb74dfc
* Kolla-Ansible version = 14.8.1.dev66

Hi Muhammad, I've just run into the same issue. It seems it might be related to

tl;dr: Yoga uses RabbitMQ 3.9, which is not compatible with latest Erlang 26.

In my environment, I have seen this incompatibility:

(rabbitmq)[root@node-0 /]# rabbitmqctl --version
(rabbitmq)[root@node-0 /]# erl --version
Erlang/OTP 26 [erts-14.0.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit:ns]

no longer affects: kolla-ansible
Changed in kolla:
status: New → Invalid

    [yoga-only]: Fix erlang versions

    According to [1] - RMQ 3.9 supports Erlang 25.2 at maximum.

    Unfortunately there is no repository that provides erlang 25.2
    for aarch64, so it will stay on 25.3 which proves to be bringing
    some issues.
