Enable Virtualization in windows 10 azure vm

Question

Enable Virtualization in windows 10 azure vm

Satyam Chauhan 607

Hi,

I am using an azure VM, Windows 10 Enterprise, version - 21H2, OS build - 19044.3086.

I am installing WSL2 and installed Ubuntu from windows store on it, for this I enabled nested virtualization using - https://learn.microsoft.com/en-us/azure/lab-services/how-to-enable-nested-virtualization-template-vm-using-script?tabs=powershell

I enabled the Virtual Machine Platform as well from "Turn Windows feature on or off"

When I try to open the ubuntu app it gives following error -

Installing, this may take a few minutes...

WslRegisterDistribution failed with error: 0x80370102

Please enable the Virtual Machine Platform Windows feature and ensure virtualization is enabled in the BIOS.

For information please visit https://aka.ms/enablevirtualization

Press any key to continue...

Using some links I tried to enable Virtualization using the following command, but it gives error, I replaced <My Vm Name> with actual VM name.

PS C:\Windows\system32> Set-VMProcessor -VMName <My Vm Name> -ExposeVirtualizationExtensions $true
Set-VMProcessor : Hyper-V was unable to find a virtual machine with name "provided VM Name".
At line:1 char:1
+ Set-VMProcessor -VMName <VM Name> -ExposeVirtualizationExtensi ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (:) [Set-VMProcessor], VirtualizationException
    + FullyQualifiedErrorId : ObjectNotFound,Microsoft.HyperV.PowerShell.Commands.SetVMProcessor

Please help, how can I resolve this issue.

Hi Satyam,

When creating the VM, please make sure the size you select supports Nested Virtualization and you select Standard security, as shown in screenshot below:

azure security type standard

For VM sizes less than v5 you need to select Standard because Nested Virtualization isn't supported with Trusted Launch.

Please click Accept Answer if the above was helpful. If the above doesn't resolve the issue please add a comment with more details such as the VM size you selected.

Thanks.

Hi,

Thanks for your response. My VM had the configuration of security type as Trusted Launch only, so I created another VM with following configurations:
OS - Windows (Windows 10 Enterprise)
Size - Standard B4ms (4 vcpus, 16 GiB memory)
Security type - Standard

But still I am getting the same issue as earlier.

Please help!

@Satyam Chauhan B4ms VM size doesn't support nested virtualization. You need to use size that supports it. Here is the specifications for B series, if you scroll down you will see it says "Nested Virtualization: Not Supported":

https://learn.microsoft.com/en-us/azure/virtual-machines/sizes-b-series-burstable

Standard_D4s_v3 supports it and has similar vCPUs and RAM:

https://learn.microsoft.com/en-us/azure/virtual-machines/dv3-dsv3-series#dsv3-series

On the page above you can click different VM series on left and then check if it supports Nested Virtualization.

Hi TP,

I have spent 6-8 hours trying to create VMs with various versions of operating Windows operating systems, processor types. Wasted lots of time in creating VMs and installing Dockers on these new VMs.

Nothing worked.

Even when the VM description says the "Nested Virtualization" is ENABLED, the Docker was not able to run.

Your comment of choosing security type "Standard" finally made the magic.

Thank you :-)
