Free built in Hyper-V in Windows is a fantastic free product
In an effort to self host my Linode server my research has led me to decided to Virtual Machine to run a Debian distribution. Those interested might want to know that I have fully explored other options mainly OpenWRT or running Debian on a beefy MIPS processor; former failed due to lack of proper packages, latter failed due to the difficultly hacking Debian onto MIPS and the lack of tailored router interface.
The two main products a quick Google search returns are VirtualBox and VMWare Player, both are free but I was leaning towards VMWare because - it is my understanding - it's native format can be uploaded to an online host as is. However to my big surprise Microsoft provides it's own Virtualization software built into Windows 8.1.
It's fantastic to use, full of professional features such as VM auto start for and seems to have better virtualisation as I was able to adjust the console's frame buffer resolution without a problem but could not do so in VMWare virtualization.
To install in Start screen type 'Turn Windows features on or off' and locate the Hyper V grouping. While you there notice there are other goodies like a solid free web server 'ISS'
