I think is not the same thing.

I'm not trying to configure the kernel.

The problem here is, I download RH8 from the Red Hat Developer.

In the first stage of the installation I'm able to register the subscription, but the error during the packages installation, it tries to register again and fails.

So the problem is due to the Red Hat developer registration.

A quick search for this line finds me:

Perhaps check if the above bug applies to your case?
If so, you can try to work around it by installing 8.2 and then upgrade.
Also, perhaps attach your logs to that bug, and/or comment adding
relevant information from your case.

In any case, this does not sound like an oVirt bug to me.

Thanks and best regards,
