VirtualBox

[VirtualBox] let’s you run guest machines. I need to run an old version of Ubuntu and VirtualBox didn’t require me to reboot and turn on the virtualization settings.

[Ubuntu 12.05]

I ended up needing [Ubuntu 14.04 64-bit] to get recent enough C/C++ compiler tools for cmake and libcurl.

Setup:

Intall VirtualBox Guest Add-ons:
sudo apt-get install virtualbox-dkms
sudo apt-get install virtualbox-guest-dkms
sudo apt-get remove libcheese-gtk23
sudo apt-get install xserver-xorg-core
sudo apt-get install virtualbox-guest-x11

sudo apt-get install autofs
