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.
- 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
- Create a virtual machine. See the prerequisites above for the required OS and VM versions.
- 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.
Set-VMProcessor -VMName <VMName> -ExposeVirtualizationExtensions $true
- Start the virtual machine.
- 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.
