thanks Gianluca for the well thought out response. I started over and
tried to install RHEL 8 with ovirt 4.4. I ran into a few problems, which
may be related. First was that the module javapackages-tools could not be
found.
# yum module enable javapackages-tools

missing groups or modules: javapackages-tools
Then, the install of ovirt-engine relies on apache-commons-compress, but no
version could pass module filtering.

Sorry for the length of these errors. I just thought --nobest might find
something for me.
Here is the enabled modules....
