 ## Instead of trying to keep 4 separate playbooks up to date, let's do it all here.
 ## The only difference from using multiple playbooks is we need to specify `-e libvirt=true` and/or `-e permanent=true` if the builder will be permanent/static.
 ## Tested on: CentOS 7, CentOS 8, Xenial, Bionic, Focal, Leap 15.1 using ansible 2.8.5
