PhpVirtualBox Version 5
We have been using VirtualBox with PHPVirtualBox as our back end system since late 2013 and we just built a new server based on VirtualBox version 5 in August 2015. The build and install went really smooth. TehcMint has a great guide that shows you how to get the sever setup and configured. Our new system is built on a AMD 1100T with 6 cores, 8gb Ram and boots from a 128GB SSD and data store is a pair of 240GB Mirrored SSD.
