[Hyper-V] Nested VM can’t start

May 11, 2016 at 6:00 am in Microsoft, Nano Server, Windows Server 2016 by Florent

With Windows Server 2016 TP4, Microsoft added a new feature, Nested Hyper-V. This feature give you the possibility to do virtualization in VMs thatare running on Hyper-V.

On 27th of April, Microsoft has released the TP5 version of Windows Server 2016. Because I’m using my Azure Stack server has host, who is running on Windows Server 2016 TP4, I tried to test the Nested Hyper-V TP5 on this server. I created a Nano Server with the Hyper-V role and I created a VM WS2016TP5 on it:

SNAGHTML9682b64

I started this VM and I had the following error:

Failed to start the virtual machine ‘WS2016TP5’ because one of the Hyper-V components is not running

The problem is that if you want to run the TP5 version of Nested Hyper-V, your Hyper-V server MUST be on TP5 too. I hope I helped you Sourire
