Last time I spent some time looking into the tungstenfabric organization in github to find whether the integration between OpenStack and Tungsten Fabric is still maintained (mainly to determine whether we can drop support for that integration from puppet-neutron), I found that even the neutron plugin was quite unmaintained. The core problem I saw there was that they capped keystoneauth1 and openstacksdk to quite old versions[1] and I suspect that the plugin is not compatible with recent releases of OpenStack. I've checked the same now but it seems that problem still exists. [1] https://github.com/tungstenfabric/tf-neutron-plugin/blob/master/requirements... I may advise you to contact Tungsten Fabric community too to see if anyone is really maintaining the plugin. Regarding the necessity, it would probably depends on your use case as well as requirements(functionality/performance/etc). If you need just standard network functionality and reasonable performance then using a standard backend such as OVN can be enough. On 8/5/25 9:59 PM, Michał Nasiadka wrote:

Hello Thamanna,

No, Kolla-Ansible did never support Tungsten Fabric as part of a standard deployment. There was a Kolla-Ansible fork under the TF namespace long time ago - but it looks unmaintained for very long time: https://github.com/tungstenfabric/tf-kolla-ansible <https://github.com/tungstenfabric/tf-kolla-ansible>

Hello OpenStack Community,

We are currently using *OpenStack Kolla Ansible (2023.1 release)*. As part of our networking design, we are evaluating the possibility of *integrating Tungsten Fabric (TF)* with *Neutron*.

I would like to clarify the following points:

1.

*Compatibility* – Does the Kolla Ansible 2023.1 version officially support integration with Tungsten Fabric?

2.

*Reference Material* – If supported, could you please suggest any official documentation, blogs, or reference implementations that describe the integration process?

3.

*Integration Guidance* – What would be the recommended approach for integrating TF with Neutron in a Kolla-based deployment? Are there any specific configuration patterns or community best practices we should follow?

4.

*Necessity* – In the context of building a public cloud, is Tungsten Fabric integration considered mandatory for production-grade networking, or can similar functionality be achieved with the default Neutron backends (e.g., OVN/OVS)?

We are currently at the early stages of our deployment plan and can make architectural changes before the release. Any guidance, experiences, or resources from the community will be highly valuable for our decision-making process.

Thank you in advance for your support.
