Hi Bakursait,
"optimal" is in the eye of the beyonder really. Depending on your installation method, ubuntu 22.04, Rocky Linux 9, Debian 11 & 12, plus CentOS stream 9 are all good bases. More commercial, RHEL/Oracle are equals with the more free as a beer distros.
My personal go to is rocky Linux 9 and kolla-ansible for deployment. Though I use ubuntu on my mac mini based lab (ubuntu does mac hardware a bit better than Rocky).
https://docs.openstack.org/kolla-ansible/2023.1/user/quickstart.html
The above link assumes an all in one node, so that may present some limitations to what you are looking to do, but it's a good place to start. We have 50+ node Openstack clouds on Rocky with kolla-ansible, it's a great combo, but no means the only combo. We have a broad echo-system in this community.
Good luck!
Cheers. Michael

Hello All,
I'm currently pursuing my PhD and my research involves utilizing OpenStack. I've encountered some challenges while attempting to install it on Ubuntu 22.04. I'd greatly appreciate it if you could recommend the most reliable Linux Distribution (along with the version) that has worked well for you. Additionally, any up-to-date tutorial suggestions for installing OpenStack would be incredibly helpful, as many of the resources I've come across seem to be outdated.
Thanks for your assistance!
Best regards, Bakursait
