Hi,

I have installed Hyper-V on a Windows 10 machine, installed 4 VMs, 1 DC, 1 Windos10 and 2 Azure Stack HCI Cluster VMs. I enabled Nested Virtualization Con both the Cluster VMs but when I am trying to setup Azure Stack HCI on Windows Admin Center on the Install Features Page it gives the below error message.

Please ensure nested virtualization is enabled in order to successfully install Hyper-V on hcinode1.

Please ensure nested virtualization is enabled in order to successfully install Hyper-V on hcinode2.

I see it says enabled for both the VM when checking.

PS C:\WINDOWS\system32> Set-VMProcessor -VMName HCINode2 -ExposeVirtualizationExtensions $true

PS C:\WINDOWS\system32> Set-VMProcessor -VMName HCINode1 -ExposeVirtualizationExtensions $true

PS C:\WINDOWS\system32> (Get-VMProcessor -VMName HCINode1 ).ExposeVirtualizationExtensions

True

PS C:\WINDOWS\system32> (Get-VMProcessor -VMName HCINode2 ).ExposeVirtualizationExtensions

True

Please kindly help and share your thoughts if you guys have a solution for this.

    This has been resolved.

    I had the DC as Gen1 and the VMs as Gen2, recreated the VMS and solved the problem.

    How can the DC being gen 1 make any difference? I am having this issue too and I have nested virtualization turned on using powershell on the host machine for all three hci VMs but I'm still getting this error. I have other Hyper-V nested virtualization VMs running perfectly fine but the azurestacks do not work the same.
