How to setup your VMWare Fusion 6 images to use static IP addresses on Mac OS X

At Crush + Lovely, we use Railsmachine's Moonshine to automate the configuration of our servers. When writing our deployment recipes, VMWare Fusion's ability to take snapshots and rollback to these snapshots is a huge timesaver because it takes just seconds to roll a server image to it's original state.

When you're just configuring a single server, having a static IP address for your server image isn't too important, but when you're configuring multi-server setups, it can be useful to duplicate a number of server images and give each a static IP address so you can consistently deploy to them. While not documented well at all, it turns out that this is relatively easy to accomplish in four simple steps.

1. Determine the MAC address of your guest machine

Let's say you have a guest machine with the name ubuntu-lucid-lynx-base

Open .bash_profile

Add the two ENV variables like so:

i.e. ENV['TWITTER_KEY'] && ENV['TWITTER_SECRET']
