Just to add to what's already been said, from the perspective of Ubuntu and OpenStack, we have the following info.

* https://ubuntu.com/about/release-cycle#openstack-release-cycle - maps OpenStack releases to Ubuntu releases and the cloud archive (LTS + OpenStack release). Note this is for packages as well, regardless of whether Charmed OpenStack is used.

* https://openstack-ci-reports.ubuntu.com/reports/cloud-archive/index.html - the cloud archive; shows every version against every release pocket for distros and cloud archives.

To clarify, we do a release of OpenStack packages each cycle and either carry them in the distro release (e.g. 22.04 (jammy) which carries Yoga). We also have the UCA (Ubuntu Cloud Archive) which carries the OpenStack releases that don't coincide with the Ubuntu LTS release, which for example supports 2023.1 on Ubuntu 22.04. https://docs.openstack.org/install-guide/environment-packages-ubuntu.html explains how it works.

Cheers

Alex.

Hey, all. I'm trying to figure out which OpenStack versions support
which Linux distros and versions, both guest-side and controller/compute
side. Does such a document exist, or is there a generally good place to
look for each version of OpenStack?

Thanks!
