XML FeedsIf your processor does not support Virtualization Technology then you can't run Windows 8 in Virtual Box....you will get a black screen of death. In order to find out if your CPU supports hardware Virtualization Technology you can download the Intel Processor Identification Utility here http://www.intel.com/p/en_US/support/highlights/processors/toolspiu/
Run it and look if Virtualization Technology is enabled...see the bottom of this picture
if it is enabled then you need to turn it on in your BIOS, to see how to configure BIOS, go to this page http://www.microsoft.com/windows/virtual-pc/support/configure-bios.aspx
After BIOS has been configured, you need to do a reboot, shut down, wait about 10 seconds and then start up again.
Now you are ready to make the changes in Virtual Box
Click on settings, then system and then on the motherboard tab, click on Enable IO APIC
On the Processor tab, click on Enable PAE/NX
Finally on the Acceleration tab, click on both Enable VT-x/Amd-v and Enable Nesting Paging
Now you are all set...have fun

I'm trying the 32 bit developer preview on Virtual Box 4.0.12 with Host as a WinXpSP3 system. Even with the above settings I keep getting a "computer needs to restart" error. Anyone faced/solved this issue? 
Did you change it in the BIOS? 
What version of Virtualbox is required? I have 4.0.0 
Thanks, this works great! 
Has anyone had an issue on Virtual Box where you're only able to click on certain icons? For example, I can launch the control panel or desktop with a single click but when I try the IE tile it just moves and nothing happens. I can go to the desktop and launch IE without issue. Not sure what to try….
