Enable hardware virtualization in BIOS/UEFI on PCs (VT-x and AMD-V)

Hardware virtualization technologies, such as Intel’s VT-x and AMD’s AMD-V, are essential for running virtual machines with optimum performance. They enable virtualization software such as VirtualBox, VMware or Hyper-V to directly access processor resources for faster instruction execution. These features are not always enabled by default and require BIOS/UEFI intervention. This guide explains how to check and enable hardware virtualization on your PC, so you can take full advantage of virtualized environments.

Check whether virtualization is enabled on your PC

Before accessing the BIOS/UEFI, it’s best to check whether virtualization is already enabled. Under Windows, follow these steps:

1. Open Task Manager andaccess the Performance tab.
2. Select Processor and check whether the Virtualization line indicates Enabled or Disabled.

If virtualization is disabled, it must be enabled in the BIOS/UEFI.

Enable VT-x or AMD-V hardware virtualization in BIOS/UEFI

1. Restart your PC.
2. Access BIOS/UEFI by pressing the key corresponding to your motherboard at boot-up(Suppr, F2, F10, or Esc depending on the model).

Discover the list of BIOS / UEFI access keys by manufacturer.

1. Once in BIOS/UEFI, navigate to the Advanced or CPU Configuration tab.
2. Search for Intel (VMX) Virtualization Technology or AMD SVM Mode (depending on your processor) and enable this option (Enabled).
3. Save your changes and restart your PC.

Once you’ve followed these steps, you can check again in the Task Manager that virtualization has been enabled.
