Provision Multiple Virtual Puppet Slaves with Vagrant

For testing, it’s convenient to provision many virtual slave computers to your master.

This Vagrant file installs two virtual computers and automatically configures them as slaves to a puppetmaster in a predefined IP address.
Advanced stuff warning: Using this sample configuration requires fluency in command line, Puppet master-slave architecture and knowing the basics of vagrant and virtualbox.
