Description
I installed VirtualBox 4.3 and it doesn't detect VT-x any more.
It trows the "This kernel requires an x86-64 CPU..." error.
It works all good on previous versions. I even removed VirtualBox 4.3 and installed VirtualBox 4.2.18 without restarting once and it worked in 4.2.18.
I attach a screenshot of the error and DxDiag.

Change the guest OS type to "64-bit" or use the command:
VBoxManage modifyvm <vmname> --longmode on
