discussion here. The result of such a change is that soon there will be no way to install vdsm on Fedora, because we need only one maintainer that does not care about Fedora.

Then we cannot test vdsm with upstream libvirt and qemu, which will harm our ability to develop

Fedora, using upstream libvirt and qemu or upstream patches.

Another example, if you want to test sanlock fixes that will be available in RHEL 8.3, the only way to do this now is on Fedora - the fixes are available in updates-testing. So we can make sure our code is compatible with new sanlock now, or wait until 8.3 is out and find about regressions very late before the release.

This is a common trend in the last 6.5 years - oVirt is not tested on Fedora (e.g. no ovirt systems on Fedora), leading to late detection of issues, and regressions in new versions in RHEL/CentOS.

What we should do instead is focus on Fedora support and testing early upstream packages.

Currently oVirt is tested on CentOS 8.1, which is irrelevant to oVirt 4.4. What we really need is to test on RHEL 8.2 nightly builds, but this is not available to the public and cannot be used by an upstream project. But Fedora 32 is available and includes all the packages needed for valuable testing, so this should be our main platform for testing.

CentOS stream could be a good solution for testing, if we could get the advanced virt module *before* the module is released in RHEL. Otherwise we test on old version and we don't detect issues in time.
