Intel Virtualization Technology

Last Updated : Jun 06, 2026 |

Intel CPUs require EM64T and Virtualization Technology (VT) support in the chip and in the BIOS to run 64–bit virtual machines.

All Intel Xeon processors include:

  • Intel Virtualization Technology

  • Intel Extended Memory 64 Technology

  • Execute Disable Bit

Ensure that VT is enabled in the host system BIOS. The feature is also known as VT, Vanderpool Technology, Virtualization Technology, VMX, or Virtual Machine Extensions.

Note:

The VT setting is locked as either On or Off when the server starts. After enabling VT in the system BIOS, save your changes to the BIOS settings and exit. The BIOS changes take effect after the host server reboots.

Other suggested BIOS settings

Servers with Intel Nehalem class and newer Intel Xeon CPUs offer two more power management options: C-states and Intel Turbo Boost. These settings depend on the OEM make and model of the server. The BIOS parameter terminology for current Dell servers are described in the following sections. Other server models might use other terminology for the same BIOS controls.

  • Disabling C-states lowers latencies to activate the CPUs from halt or idle states to a fully active state.

  • Intel Turbo Boost steps up the internal frequency of the processor if the workload requires more power. The default for this option is enabled. Do not change the default.
