title: Windows 8 VirtualBox Vt-x not available
body: <p>I just upgraded my host machine from windows 7 to windows 8. I was running an OSX VM under VirtualBox for iOS dev. Since the upgrade I can no longer run my OSX VM. I get the error VT-x not available (VERR_VMX_NO_VMX). </p>
  
  <p>I checked the bios setting and hardware virtualization is still on. Which would only make sense since the only thing that changed was the OS. </p>
