oracle vm virtualbox vt x is disabled in the bios

Many thanks to ecsdrive for coming up with the fix! It's unfortunate that the devs/support seem to be so hostile and unhelpful towards the users, at least the user community is helpful. You need to be able to work with them, not insist they change their BIOS configuration. If this means that VB can not read the BIOS settings correctly, that is still a problem with VB, not an issue with the BIOS, especially when you are talking about a brand as large as Dell. VB on Win is simply unable to properly read and work with the host hardware and virtualization support apparently.

This problem does not occur in the Mac version of 3.2.12, only the Windows version. If I try to install anyway, the boot loader on the DVD fails to start. Virtualbox however insists that VT-x is not operational when I attempt to launch a 2008 R2 guest for first install. For example, I have an Optiplex 755 with an E8200 which supports VT-x per and has all virtualization options on in the BIOS. As of version 3.2.12 this error is still reported on all Dell systems with Core2duo chips. This is apparently a bug in VirtualBox that has not been fixed.
