'Vagrant-dspace' uses Vagrant–a tool that creates/destroys VMs–and Puppet to auto-install latest DSpace on the VM provider of your choice (so far primarily tested with VirtualBox). Currently, it's only usable as a testing/demo of DSpace (not for production). It makes installing DSpace for testing/demos a simple process that is entirely automated.

Some example use cases for 'vagrant-dspace':
• Lets you easily install the latest version of DSpace on a Virtual Machine in order to try it out or test upgrades, etc.
• Lets you easily setup an offline/local copy of DSpace for demos at conferences or similar.
• Lets you quickly setup a DSpace development environment on a Virtual Machine. You'd need to install your IDE of choice, but besides that, everything else is installed for you.
• Vagrant VMs are "throwaway". Can easily destroy the VM and recreate at will for testing purposes or as needs arise (e.g. vagrant destroy; vagrant up)
• This work began as a collaborative project between Tim Donohue and Hardy Pottinger, but has now been more broadly accepted.
