Submission + - VirtualBox 2.1 supports 64 bit VM in 32 bit host (virtualbox.org)
Stephen Birch writes: Following closely behind the mid November 2.06 release of VirtualBox, Sun Microsystems has released version 2.1 (release notes here). This has a number of new features but one of the most interesting is the ability to run a 64 VM inside a 32 bit host. Another useful feature is integrated host based networking, no more fiddling around with network bridges. Sun is really giving VMWare a run for their money.
