Testing with DevStack in networking-ovn - things have changed

[Tim Coote]

This bug tracker is for errors with the documentation, use the following as a template and remove or add fields as you see fit. Convert [ ] into [x] to check boxes:

- [x ] This doc is inaccurate in this way:
-- https://opendev.org/openstack/networking-ovn.git is no longer a separate project, so cloning this is redundant.
-- the create-stack-user.sh script does not work as displayed with Centos Stream9 as the environment variable HTTP_IP does not make it to the sudo environment. So the script falls over when importing stackrc.

- [ ] This is a doc addition request.
- [ ] I have a fix to the document that I can paste below including example: input and output.

The networking-ovn project and repository is no more as of the Train release, it was all moved into the neutron repository. So I'm not sure there's anything to fix here as there is no master branch and I don't believe it's expected to install on Stream 9 from this repo on Train.

[Tim Coote (mtimc)]

Is the documentation supposed to be relevant to the current head, or is the intention to sustain many different working versions (for many different snapshots/old versions)?

The comment about Train implies the latter (I think), in which case it's going to be really hard for users to find the right documentation without better signposting (I think).

Are you saying that the installation described is not supposed to work on the current Centos Stream? I think that's the only current Centos that has the quite old Python 9 on it, so I'm a bit surprised. Is there a list of what works where?

[Brian Haley (brian-haley)]

I don't know what's up with docs.openstack.org but it must be treating Train as "latest" as master is no more (see https://opendev.org/openstack/networking-ovn/src/branch/master/). Typically docs can be had for each release since things do change, latest is just a place keeper.

To install Neutron with OVN using devstack you don't need to do anything special, it's actually the default in devstack since last year (?) using the code that exists in the neutron repository. When it comes to a distro I'm not sure since it would be up to the maintainers or community to add support for things.
