Description of problem:
According to https://github.com/myllynen/misc/ the Official RHEL 8 Qcow2 image weights more than it could (compare to the other alternatives listed in the page). It also uses the net.ifnames=0 boot parameter which is not supported in general so looks not to be a good choice for a presumable generic-purpose image.
Please consider streamlining and adjusting the RHEL 8 rhel-guest-image.
Version-Release number of selected component (if applicable):
RHEL 8.0 Beta
