I've been hearing great things about puppet, chef, vagrant, and friends for a while now, but since I work on my own I tend to either develop straight onto my ubuntu machine or grab an appropriate existing VM and use that. So I read about this brave new world of virtualisation but (as with most tools) they can be hard to introduce on your own, and I didn't. [...] Then I went to WhiskyWeb, which had a hackathon [...] with the shiny new technology all packaged for me, I decided it was time to take a look!

She shows you how to get the VM started up using vagrant, pausing the instance and removing it all together (destroy). She also includes the command to directly access the VM via ssh and links to the joind.in project with its sample puppet configuration and Vagrant file.
