What CPU extensions are a prerequisite for installing the Hyper V role when using an Intel or AMD processor?

Intel® Virtualization Technology abstracts hardware that allows multiple workloads to share a common set of resources. On shared virtualized hardware, a variety of workloads can co-locate while maintaining full isolation from each other, freely migrate across infrastructures, and scale as needed.

Intel® Virtualization Technology requires a computer system with the following elements. Contact your vendor for more information.

• A processor
• Chipset
• BIOS
• Operating system
• Device drivers

Here is the list of all Intel® Processors supporting Intel® Virtualization Technology

To find out if your Intel® processor supports Intel® Virtualization Technology, use one of the options below:

Q: How can I check if my Intel processor supports Intel® Virtualization Technology (VT-x) ?

1. Identify your Intel® processor. Refer to How to Identify My Intel® Processor?
2. Visit the product specification site (ark.intel.com). Enter the number of the processor in the search box located on the right side.

   On the processor product page, and under Security & Reliability, check to see if Intel® Virtualization Technology (VT-x) is supported.

   Using Intel® Core™ i7-12700K processor as an example:

   1. Enter the number of the processors in the search box.
      

   2. On the specification page for the processors, and under Security & Reliability, look for the Intel® Virtualization Technology (VT-x) field.
      

Q: How do I enable or disable Intel® Virtualization Technology (VT-x)?

With a VT-x supported Intel® Processor and a VT-x supported BIOS, VT-x can be enabled or disabled in BIOS. Refer to your motherboard vendor for exact instructions if the option is not available in BIOS.

Q: My processor supports Intel® Virtualization Technology (VT-x) but I am unable to enable it in the BIOS.

If the processor supports VT-x but the option to enable or disabled in BIOS is available, contact your motherboard vendor to see how to get that option enabled.

Q: How can I tell if Intel® Virtualization Technology (VT-x) is enabled or disabled in my system?

You can use the Intel® Processor Identification Utility to verify if your system is capable of Intel® Virtualization Technology.

Using the tool, Select the CPU Technologies tab. See if the Intel® Virtualization Technology options are checked or not.

Here is an example to show that the Intel® Virtualization is available.

Here is an example to show that the Intel® Virtualization is not available.

If Intel® Virtualization Technology is not checked in the tool, there might be a possibility your processor still supports Intel® Virtualization Technology, but it is already being used by some software that uses a hypervisor. In that case, you can also use the Task Manager to verify the situation.

Here is an example to show Intel® Virtualization is enabled using Task Manager:

Using the table below,  you can see if your processor supports Intel® Virtualization if it is disabled, and additional information.

Q: If the Intel processor supports Intel® Virtualization technology (VT-x), should the chipset, OS, drivers support that too?

Intel® VT-x support requires that both the processor and BIOS support it. Although, if VT-d (Virtualization Trusted I/O is also needed, the BIOS, chipset, and processor must also support it.

Q: How do I disable Intel® Virtualization technology (VT-x) if BIOS option is not there?

With a VT-x supported Intel® Processor and a VT-x supported BIOS, VT-x can be enabled or disabled in BIOS. Refer to your motherboard vendor for exact instructions if the option is not available in BIOS
