Wikipedia said, VirtualBox is an x86 virtualization software package, originally created by German software company innotek, now developed by Sun Microsystems as part of its Sun xVM virtualization platform. It is installed on an existing host operating system; within this application, additional operating systems, each known as a Guest OS, can be loaded and run, each with its own virtual environment.
Supported host operating systems include Linux, Mac OS X, OS/2 Warp, Windows XP, Windows Vista, and Solaris; there is also experimental port to FreeBSD. Supported guest operating systems include various versions of DragonFlyBSD, FreeBSD, Linux, OpenBSD, OS/2 Warp, Windows, Solaris, Haiku, Syllable, ReactOS and SkyOS. The latest version also supports Windows 7 beta and release candidate 1.
The Storage Network Industry Association (SNIA), defined virtualization as:
- The act of abstracting, hiding, or isolating the internal function of a storage (sub) system or service from applications, compute servers or general network resources for the purpose of enabling application and network independent management of storage or data.
- The application of virtualization to storage services or devices for the purpose of aggregating, hiding complexity or adding new capabilities to lower level storage resources.
Storage can be virtualized simultaneously in multiple layers of a system, for instance to create HSM like systems.
Hu Yoshida, the VP and CTO of Hitachi Data Systems, explained clearly about this definition here..
