Sandro,
I am sorry for picking the wrong forum to post into, it seemed a naturally correct place because I was suggesting a shift in the development choices being made for oVirt and how it is produced.
I hear what you are saying. However, that means that all the ISOs that are published for people to download based on CentOS are going to be viewed by the Linux community that has an interest in trying oVirt as a potential learning path to RHV as alpha/beta quality. CentOS since "going upstream" has been heavily devalued by the open source community for useful testing or any real work. Again, that is just a fact or people would not be in a mad rush to move to Rocky Linux or Alma Linux. At any rate, just my two cents worth which may be all my opinion is worth! :)
I am not trying to be argumentative, just I think that supplying oVirt using an underpinning OS that is quality based as opposed to CentOS would be a worthy endeavor to encourage interest in oVirt.
Although I have not had a chance to gather and post the facts together, I did try to do an install of it in my ProxMox virtualized environment (again for testing) and met with a number of issues causing a failed installation and eventually gave up. Now that I realize it is CentOS based, I am not even think it is worth dealing with as the result will not be a production quality install. I will read the link you provided regarding installing oVirt on REL or a "derivative clone".
Thanks for your most brisk and thoughtful response and I wish you a healthy and safe day in these challenging times.
