Download Virtualbox 2.0.4

Sun Microsystems released version 2.0.4 of Virtualbox yesterday. This program can be used to install another operating system on a computer in a virtual environment. Virtualbox runs under Windows 2000 and higher, Mac OS X, Linux and Opensolaris and can handle a large number of guest operating systems.

The software is available in two different versions. The full version has more functionality, such as support for USB ports and remote display protocol, but is only free for private use and evaluation purposes. This extra functionality is closed source and is missing in the other version: the open source version. Version 2.0.4 is a so-called maintenance release and contains no new functionality. However, several improvements have been made and a number of bugs have been fixed. Below is the changelog for this release:

The following items were fixed and/or added:

• VMM: better error reporting for VT-x failures
