Sun xVM VirtualBox 3 Released

As you may know by now, I am a big-time VirtualBox fan. Version 3 has been released, which is a large update for the platform. The updated functionality includes:

Up to 32 vCPUs per guest (Rockstar).
Experimental graphics support for Direct3D 8 and 9.
Support for OpenGL 2.
Toolbar for use in seamless and full-screen modes.

These features supplement a robust offering for VirtualBox that in most categories is on par with any Type-2 hypervisor. If you haven't checked out VirtualBox, it may be time to do so. The footprint is small (63MB), the price is right (free) and it's quick.

One of the new features is the toolbar for use in full-screen or seamless modes. I use seamless mode frequently. Seamless mode basically puts the guest on top of your current host operating system for an easy transition between systems. With the new toolbar, a floating control panel allows you to switch back and forth easily (prior versions required a keystroke) between the host and the guest. The toolbar also allows virtual media to be assigned without leaving the full-screen or seamless session. Figure 1 below shows the toolbar appearing on a VM in seamless mode:
