Virtualization is the process creating a virtual version of a resource such as an operating system, network resource or storage device. Virtualization of an OS involves hosting an OS on another OS using a virtualizer such as Oracle VirtualBox. Various Linux distributions such as openSUSE, Ubuntu, and Fedora are available. In this article we'll discuss hosting openSUSE, Ubuntu, and Fedora on Oracle VirtualBox running on Windows OS.
