This must be something asked of RedHat support quite a bit because it was covered thoroughly in their UNIX sysadmin training material for Redhat 7 and there's a published solution on their site from years ago. [1]

Redhat documentation is pretty decent and access is free via their developer program [2]. The program gives one free bare metal license for a system with up to 8 sockets that can host unlimited VMs. [3]

I realize HN is all about open source and free software but for people looking to work in a corporate environment that uses RHEL, Redhat does try to make entry at least possible for those who can self study.
