Virtualization applications don't work together with Hyper-V, Device Guard, and Credential Guard

Many third-party virtualization applications don't work together with Hyper-V. Affected applications include VMware Workstation and VirtualBox. These applications might not start virtual machines, or they may fall back to a slower, emulated mode.

These symptoms are introduced when the Hyper-V Hypervisor is running. Some security solutions are also dependent on the hypervisor, such as:

  • Device Guard
  • Credential Guard

Cause

This behavior occurs by design.

Many virtualization applications depend on hardware virtualization extensions that are available on most modern processors. It includes Intel VT-x and AMD-V. Only one software component can use this hardware at a time. The hardware cannot be shared between virtualization applications.

To use other virtualization software, you must disable Hyper-V Hypervisor, Device Guard, and Credential Guard. If you want to disable Hyper-V Hypervisor, follow the steps in next two sections.

How to disable Hyper-V

You can disable Hyper-V Hypervisor either in Control Panel or by using Windows PowerShell.
