The biggest change in xVM VirtualBox 2.0 is the new support for 64-bit versions of operating systems like Windows Vista and Red Hat Enterprise Linux, in addition to all other major host operating systems. VirtualBox also offers a new user interface for the Mac platform, improved networking for the Mac OS X and Solaris OS, as well as improved performance, especially on AMD chips.
