Virtual Box 3.0 released

Soon after the second beta, Sun has released the final version of VirtualBox 3.0.

One of its new features is Guest SMP (Symmetric Multiprocessing) with up to 32 virtual CPUs. To use it, a host CPU capable of VT-x or AMD-V is needed.

Besides OpenGL 2.0 support for Windows, Linux and Solaris guest systems, the new version comes with an experimental Direct3D support for version 8 and 9 on Windows guest systems.

Further information can be found in the changelog.

VirtualBox 3.0 can be downloaded from the official download site or on vbox.me for the portable version.

Also still experimental, the Direct3D support is another step in the direction of virtualized GPUs. In the future, direct hardware support should make this even faster and more stable.
