Compiz in a box
By Calum on Apr 08, 2009
In VirtualBox 2.2.0, which was released today, that is. The new OpenGL acceleration for Linux and Solaris guests allows compiz to run very nicely in a virtual machine. (Click the thumbnail for a Theora video of compiz running in an OpenSolaris guest in OS X.)
EDIT: I suppose I ought to add there's some other cool stuff in 2.2.0 as well, particularly the ability to import/export appliances in OVF format..
