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
