Hi,           Thank you for your support. As per your advice, it will help me solve that issue.  I am currently deploying Trove using Kolla Ansible 2023.1, following the guide provided here: https://satishdotpatel.github.io/trove-dbaas-openstack/ . Despite adhering closely to the instructions, I am facing an issue where the Trove instance ends up in an error state. trove-guestagent.conf [DEFAULT] transport_url = rabbit://openstack:USI0SmaT7lPF7MJCxHPZ4alm8wiyxoihssD1VlnA@192.168.1.101:5672,openstack:USI0SmaT7lPF7MJCxHPZ4alm8wiyxoihssD1VlnA@192.168.1.102:5672,openstack:USI0SmaT7lPF7MJCxHPZ4alm8wiyxoihssD1VlnA@192.168.1.103:5672// control_exchange = trove root_grant = ALL root_grant_option = True debug = False Here are the details of my configuration and the steps I have taken for troubleshooting: Configuration: guest_info.conf [DEFAULT] guest_id=54be201a-bf4b-4235-8e55-1020aa09dedc datastore_manager=mysql datastore_version=5.7.29 tenant_id=xxxxxxx instance_rpc_encr_key=xxxxxxxx Troubleshooting Steps: Docker Status Check: root@test:~# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f698ee14d928 mysql:5.7.29 "docker-entrypoint.s…" 18 minutes ago Up 18 minutes 0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp database Telnet Connection: root@openstack-02:~# telnet 192.168.50.78 3306 Trying 192.168.50.78...

Dear OpenStack Community,

I am currently working with OpenStack Kolla Ansible 2023.1

1.setting up Trove instances as per the documentation https://docs.openstack.org/trove/2023.1/admin/building_guest_images.html Despite following the steps outlined, I am encountering some issues.

Image Not Found: I followed the steps it downloads the required packages and it creates the image directory. However, the trove image is not present in the specified path $HOME/images.

2.I have also referred to https://satishdotpatel.github.io/trove-dbaas-openstack/ and followed each step, but below issue persists. Error with Messaging and Volume Configuration: While creating a Trove instance, I encountered the following errors:

ERROR oslo.messaging._drivers.impl_rabbit [-] Failed to declare consumer for topic 'guestagent.01a5cdd0-df3c-4f61-817f-114b530a1bb3': Queue.declare: (406) PRECONDITION_FAILED - inequivalent arg 'x-queue-type' for queue 'guestagent.01a5cdd0-df3c-4f61-817f-114b530a1bb3' in vhost '/': received the value 'quorum' of type 'longstr' but current is none guest-agent[802]: 2024-07-01 09:24:13.831 802 ERROR trove.guestagent.volume [-] Volume '/dev/vdb' was not formatted.: oslo_concurrency.processutils.ProcessExecutionError: Unexpected error while running command.

Steps Taken:

Created and configured images as per the OpenStack documentation. Ensured that all Trove-related configurations are properly set up. Verified RabbitMQ configurations to avoid direct configurations and used Trove’s trove-guestagent configuration for managing RabbitMQ settings.

/etc/kolla/config/trove.conf

[DEFAULT] management_networks = ee2a2a81-178c-4d79-867b-8baf53ec236d nova_keypair = trove-ssh-key management_security_groups = 451e4b4a-58b4-4e9f-84a8-5bdb21e34cd5

/etc/kolla/config/trove-guestagent.conf

[DEFAULT] transport_url = rabbit://openstack:<RABBITMQ_PASSWORD>@192.168.8.14:5672,openstack:<RABBITMQ_PASSWORD>@192.168.8.15:5672,openstack:<RABBITMQ_PASSWORD>@192.168.8.16:5672// control_exchange = trove root_grant = ALL root_grant_option = True debug = False [oslo_messaging_rabbit] heartbeat_in_pthread = false amqp_durable_queues = true rabbit_quorum_queue = true

Request for Assistance:

Are there any other recommended methods to build the Trove guest image if the documented steps do not work?

Is there a known core issue related to the errors I am encountering with oslo.messaging and trove.guestagent.volume?

What specific configurations or logs should I check to resolve these errors?

Any additional steps or best practices for setting up Trove instances with Kolla Ansible?

Thank you in advance for your help. Any insights or suggestions to resolve these issues would be greatly appreciated.
