Intel's VT, or Virtualization Technology, is included on some Intel processors. Virtualisation Technology is a CPU extension that allows better support of operating system virtualisation programs including VMware, Microsoft VirtualPC and VirtualBox. VMware requires Intel VT or AMD-V support to run 64-bit guest operating systems. Only some Dell computers support VT and even those that do have VT disabled by default. You can enable VT, if your Dell computer supports it, in the computer's BIOS.
