Sun xVM VirtualBox 1.6 available for Mac OS X

Sun’s open source virtualization package xVM VirtualBox is out of beta for Mac OS X and available for download. Note that it can’t currently host Mac OS X (aside from the licensing issues that only allow you to virtualize Mac OS X Server). According to ZDNet Sun sells a commercial version with USB support and an RDP server.
If you download it and can’t open the archive you may need to remove the ‘.bz2’ from the end of the filename.
