From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The upside is you can treat it as just another program with a big flat file that serves as it's hard disk. You can move a VM between computers, they're universal. Hell you can move it to a data center and hardly notice a difference. You can make a snapshot, try something out, and if it borks, roll it back to a previous snapshot. You can copy the VM any number of times.
Basically it decouples operating systems from hardware so you can treat a computer like software.
