Nested Virtualization in Windows Server 2016

First off what is nested virtualization?  Nested virtualization is the ability to run Hyper-V inside of a virtualized machine.  This will allow you to install a physical host with the Hyper-V role installed and then create a virtual machine (VM) and install Hyper-V which in turn will allow you to run additional VMs.

For instructor-led Windows Server 2016 training, see our course schedule.

For Windows 10, see Nested virtualization in Windows 10 – What Is It and How to Enable It.

There are few prerequisites that must be met before nested virtualization is supported.  There is both operating system and Hyper-V setting that must be configured.  These settings are as follows:

  • Must be running Windows Server 2016.
  • The host and nested VM must be running the same build of Windows Server 2016.
  • Min 4 GB RAM on the host.
  • Dynamic RAM must be disabled on the nested VM.
  • No Checkpoints can be made on the nested VM. (if desired to checkpoint hosted VM in the nested VM must be running version 8 of the VM)
  • MAC Address Spoofing has to be enable on the nested VM NIC or a NAT Virtual Switch has to be created.

Once the VM has been configured to be a nested VM it no longer supports live migrations.

How to enable nested virtualization:

  • Create a hosted VM running the same operating system as the physical host. Then power it off.
  • Configure the host to support nested virtualization:
    • Use one of the following PowerShell Cmdlets:

Set-VMProcessor -VMName <VMName> -ExposeVirtualizationExtensions $true

or

Invoke-WebRequest https:/raw.githubusercontent.com/Microsot/Virtualization-Documentation/maste/hyperv-tools/nested/Enable-NestedVm.ps1 –Outfile ~/enable-NestedVm.ps1 ~Enable-NestedVm.ps1 –VmName <VMName>

Note:  The second cmdlet downloads a script from githubusercontent.com and then executes it.

Turn on the nested VM and you are ready to start creating VMs in your nested environment.

Until next time, RIDE SAFE!
