Take use of virtualization

Virtualization allows you to run several "seeming-as-if" (virtual) computers on one computer. This can help you

• to work in several isolated VPN environments on one computer
• to test several Linux distributions running at the same time on one computer
• for developers, to test "dangerous" changes like on the login manager or the boot sector
• in big companies, to take best use out of your computing resources
