This is a completely automated install.

OS Requirements

1 or more network interfaces with internet connectivity

1. You will need bootable media, NetBoot media does not work at this time, any minimal or full media will do. Boot media is important becuause it defines th OS major version. The OS detection looks at the OS defined in the initrd and builds based on the major version. A 9.1 OL will patch to the latest 9.x that is defined by the Distro maintainer.
