Introduction I decided this year to take part in the Fedora Virtualization Test Day on October 8th. In order to take part I needed a system with Fedora 20 installed so that I could then create VMs on top. Since I like my current setup and I didn’t have a hard drive laying around that I wanted to wipe I decided to give nested virtualization a shot. Most of the documentation I have seen for nested virtualization has come from Kashyap Chamarthy.
