Nested virtualization is a feature that allows you to run Hyper-V inside of a Hyper-V virtual machine. In other words, with nested virtualization, a Hyper-V host itself can be virtualized. Some use cases for nested virtualization would be to run a Hyper-V Container in a virtualized container host, set-up a Hyper-V lab in a virtualized environment, or to test multi-machine scenarios without the need for individual hardware. This document will detail software and hardware prerequisites, configuration steps, and limitations.

Prerequisites

  • A Hyper-V host running Windows Server 2016 or Windows 10 Anniversary Update.
  • A Hyper-V VM running Windows Server 2016 or Windows 10 Anniversary Update.
  • A Hyper-V VM with configuration version 8.0 or greater.
  • An Intel processor with VT-x and EPT technology.

Configure Nested Virtualization

  1. Create a virtual machine. See the prerequisites above for the required OS and VM versions.
  2. While the virtual machine is in the OFF state, run the following command on the physical Hyper-V host. This enables nested virtualization for the virtual machine.

  1. Start the virtual machine.
  2. Install Hyper-V within the virtual machine, just like you would for a physical server. For more information on installing Hyper-V see, Install Hyper-V.
