    Do you have virtualization extensions enabled in your BIOS? If you do not, it may need to be turned on (Intel Virtualization Extensions).

You need to enable virtualization extensions in your BIOS.

By default, this is typically turned off in the BIOS; to virtualize a 64bit CPU you have to enable the virtualization extensions in your BIOS/UEFI firmware.
