Rocks in a Box: Virtual Rocks Cluster with Oracle’s VirtualBox


I had the idea for this article while trying to create a virtual cluster using a distribution of Linux (CentOS) that is modified for parallel computing. There is some documentation out there on how to do this, but I had to piece together multiple documents to be able to get my “Rocks in a Box” running, so I’ve documented my steps here which will hopefully have all the steps required to get your parallel virtual machine up and running.
