VirtualBox is free virtualization software from Oracle that allows you to run multiple operating systems on one computer. This video demonstrates how to install the latest version of VirtualBox into Ubuntu 12.04. Since VirtualBox comes as a .deb package, VirtualBox can be downloaded from the Oracle site and installed using Ubuntu's Software Center. The installation of the VirtualBox Extensions is also covered. An additional tool Gnome-System-Tools is also installed from Ubuntu's Software Center. This is used to easily add or configure Ubuntu users to the vboxuser and vboxsf groups. Finally a working Windows XP virtual machine is shown running using the VirtualBox installation. The creation of your own virtual machine is not covered in this video. There are additional videos on this channel that demonstrate how to create virtual Ubuntu desktops and servers.
A viewer pointed this out to me. Prior to doing a kernel upgrade on your Ubuntu host with VirtualBox you should run "sudo apt-get install dkms" (after update/upgrade) to keep Ubuntu and VirtualBox Guest Additions playing together nicely.

If you want a short explanation of "What is a Virtual Machine?" is see "http://youtu.be/3QDwKS9JtZY" on this channel.

Update 5/21/2013. There have been reported problems with the guest additions 4.2.12 and Ubuntu. Workaround is to use guest additions 4.2.10 or beta 4.2.13

Update 2/4/14 If you need to upgrade VirtualBox, Ubuntu Software Center may not allow you to do an upgrade. For an upgrade or install of VirtualBox 4.2+ see "Install/Upgrade Oracle VirtualBox 4.3 in Ubuntu 12.04"- "http://youtu.be/2DfbUP2LDTk" on this channel.
