Can you tell me the steps to improve the documentation?
you need to find appropriate document, fix it and send a pull request. There's a
README [1] with the step in oVirt site git repo [1] or if you want to send a
pull request, you can find guide how to do it on [2].
Looking more into the original question you asked, it's maybe correct. I don't
know if we have any strict rules when cluster version is bumped, but it seems
in the past it was done mainly to ensure OS has specific features provided
advanced virtualization packages, which are usually available only on specific
OS version and higher. So in this case the documentation is correct (and I was
wrong in my previous answer), as OS version determines packages available on
the host and these determines capabilities of tools (like libvirt, qemu) which
oVirt is build upon.
Hopefully makes sense.

yes, it's not operating system version, but installed oVirt version on the
host (but not oVirt engine, there's only one engine and host haven't engine
installed).
Could you please improve the doc [1]?
Thanks
