Create a Linux Virtual Machine on a Mac

As a technical writer, I often need to work with different operating systems and environments to test applications. It would be a nuisance if I needed a separate machine for every test case. Happily, it’s possible to run multiple operating systems on a single machine. In this tutorial, I’ll explain how to create a Linux virtual machine (VM), using two tools: VirtualBox and Vagrant. VirtualBox provides the virtualization and Vagrant automates the creation and configuration of virtual machines.
