VirtualBox 2.1.0

Sun xVM VirtualBox

Another major release of Sun xVM VirtualBox, the 2.1.0 version, is now available for download.

From the list of major improvements, I'd like to highlight comment a few.

Experimental LsiLogic and BusLogic SCSI controllers – a long awaited feature which means VMs from VMware and many more virtualization solutions can now work in VirtualBox even if they had these controllers emulated at the time of initial VM configuration
Mac OS X users can now enjoy the support for hardware virtualization (VT-x and AMD-V) – to me, this looks like VirtualBox is taking all the right steps to attract more and more users of Mac OS
It is now possible to run 64-bit guest VMs on 32-bit host operating systems. Only recent CPUs with hardware virtualization support will allow you to give this a try. I'll have to wait a bit myself – my home PC turned out to be so old that it doesn't even support AMD-V.
Experimental 3D acceleration via OpenGL – so far provided only in a form of a specialized Windows XP/Vista VM driver, this feature hints that there may be similar approach added for Linux and Solaris VMs.
Intel Nehalem virtualization enhancements support (EPT and VPID) – this means those ones of you who are lucky enough to already own the latest generation of Intel CPUs, the Inte; Core i7 ones, can enjoy even more of a performance advantage
Full VMDK/VHD support including snapshots – again, snapshots is a common practice in managing VMs these days, so it's great to see it fully supported in VirtualBox

For more details, be sure to visit the official VirtualBox site and read the full VirtualBox 2.1.0 changelog.

My verdict: Just most major VirtualBox updates, this one is a must have for any user looking for a serious desktop virtualization solution.
