Here is everything you need to know to write a puppet configuration for libvirt, our hypervisor. This is based on a workshop with Teague Sterling on May 14, 2014.

Background

• what are puppet configs
• why do I need to write them?
• what is my best alternative if I don't write a puppet config?

Actually doing it

• location where puppet configs are stored, a) in the foreman interface, b) on disk

Deployment

• did it deploy everywhere? How to test that systematically?

What might go wrong
