Hi,

I think the big question is: Will ovirt be tested against such EL-based clones.

Well, it will be tested for those EL-based clones a few months before they'll be released, being CentOS Stream upstream to those clones.
At GA time, oVirt is already expected to work fine on latest Red Hat Enterprise Linux.
The gain on using CentOS Stream is that it will be already working also on next Red Hat Enterprise Linux.
 
Is ovirt then still 100% compatible to EL, when it will be developed for Stream, because Stream will be ahead EL.

I don't see why it shouldn't.
As an example scenario:
- oVirt 4.4.3 has been released with cluster compatibility level 4.5, requiring RHEL 8.3 + Advanced Virtualization to be able to consume the new feature. But it worked fine on CentOS 8.2 in cluster compatibility level 4.4.
- CentOS 8.3 and Advanced Virtualization  8.3 got released: 4.4.3 and the new 4.4.4 can now use cluster level 4.5.

With CentOS Stream you'll get similar scenario. At GA time oVirt 4.4.5 will be released working with CentOS Stream at release date which basically means, it will be ready to work on RHEL 8.4 but will be working with RHEL 8.3 too while waiting for RHEL 8.4 to be released.
 
Next question is, how stable will be CentOS stream?

I think pretty much. Before landing on CentOS Stream packages have been already through RHEL CI.
And oVirt wise, it will go through our CI as well.
 
At the moment, ovirt is using a lot a packages of different 3rd party repos, but the OS system core is still EL clone and stable.
With stream, also the core system is quite new and a way newer than EL, so how stable will it be?

Can you then still use CentOS stream + oVirt in production systems?

I think so, and oVirt wise we already foresee CentOS Stream in production more than one year ago: https://blogs.ovirt.org/2019/09/ovirt-and-centos-stream/

You can use OEL or any EL-based clone.

Sandro,

I have a question about "Red Hat Enterprise Linux" compatibility with oVirt.  I've always used CentOS in the past along with oVirt.  I'm running CentOS 7 along with oVirt 4.3.  I really want to upgrade to oVirt 4.4, but I'm not comfortable with the future vision for CentOS as it stands for my virtualization platform.  If I was to move to RHEL for my oVirt systems, but still stick with the "self supported" model, it's not clear whether  I can get away with using "RHEL Workstation" for my 4 hosts ($179 USD each), or whether I need to purchase "Red Hat Enterprise Linux Server" ($349 USD each).  Any feedback would be appreciated.

Thanks! 


Jason.
