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?
For a bit of clarity, OpenStack avoids using the term "support" where possible, and tries to define what that word actually means in some contexts in order to correct expectations: https://governance.openstack.org/tc/resolutions/20170620-volunteer-support.h... It sounds like you're more interested in what's tested, and for that others have already correctly pointed you to the per-release PTI documents which reflect the versions of GNU/Linux distributions and versions of Python, Node.js and Golang the software is expected to run on. There is no equivalent for "guest-side" versions of things, because OpenStack is largely agnostic to those sorts of payloads, and it comes down to what will or won't work with the local versions of things like the kernel on your compute nodes, the version of qemu you've got installed, libvirt versions, and so on. In general though, it should be safe to assume pretty much any GNU/Linux distributions can successfully run as guests as long as you have viable images for them and sufficient configuration. -- Jeremy Stanley
