Hey Jon,
Nothing will be automated if going the vmware route. The only automated way
would be to use redhats virtualization software, KVM. I built a bash
program that automates the process of installation and registration. It has
the ability to register to various channels by answering questions, etc.

Your best bet would be to just generate a simple startup script that
prompts you for input. The possibilities are endless for this kind of
method. You will build the last part of the script to remove itself from
startup only if it successfully registers.
