VirtualBox is a virtualization management application that was developed by innotek until Sun Microsystems acquired the software development company in February 2008.

You can read up on the Changelog here. In a nutshell, VirtualBox 1.6’s new highlights include Web service API, a SATA hard disk controller, experimental support for Physical Address Extensions (PAE) and a new guest addition set for the Solaris operating system.

Presently, VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows 3.x, Linux (2.4 and 2.6), and OpenBSD.
