Berrangé Describe the policy the project uses to decide which OS are supported as build platforms. This will: - Allow maintainers to determine when the minimum version of a 3rd party piece of software can be increased without negatively impacting supported platforms. - Allow tailoring of CI environments to match the intended supported build platforms.

These +platforms are used as the basis for deciding upon the minimum required +versions of 3rd party software QEMU depends on. The supported platforms +are the targets for automated testing performed by the project when patches +are submitted for review, and tested before and after merge. + +If a platform is not listed here, it does not imply that QEMU won't work. +If an unlisted platform has comparable software versions to a listed platform, +there is every expectation that it will work. Bug reports are welcome for +problems encountered on unlisted platforms unless they are clearly older +vintage than what is described here. + +Note that when considering software versions shipped in distros as support +targets, QEMU considers only the version number, and assumes the features in +that distro match the upstream release with the same version. In other words, +if a distro backports extra features to the software in their distro, QEMU +upstream code will not add explicit support for those backports, unless the +feature is auto-detectable in a manner that works for the upstream releases +too. + +The Repology site @url{https://repology.org} is a useful resource to identify +currently shipped versions of software in various operating systems, though +it does not cover all distros listed below. + +@section Linux OS + +For distributions with frequent, short-lifetime releases, the project will +aim to support all versions that are not end of life by their respective +vendors. For the purposes of identifying supported software versions, the +project will look at Fedora, Ubuntu, and openSUSE distros. Other short- +lifetime distros will be assumed to ship similar software versions. + +For distributions with long-lifetime releases, the project will aim to support +the most recent major version at all times. Support for the previous major +version will be dropped 2 years after the new major version is released. For +the purposes of identifying supported software versions, the project will look +at RHEL, Debian, Ubuntu LTS, and SLES distros.
