Error When Enabling WSL2 in Azure VM

Question

Hi,

I have created a VM in Azure, Standard B4ms class, and when I try to enable WSL2 with Ubuntu, I get the following error:

WslRegisterDistribution failed with error: 0x80370102

Error: 0x80370102 The virtual machine could not be started because a required feature is not installed.

Any ideas on why this error is happening?

Thanks

Hi @pgonza04 ,

You'll need to choose an Azure VM size that is capable of nested virtualization, check for the SKU Family with Hyper-threaded and capable of running nested virtualization:

Azure compute unit (ACU)

@pgonza04 What OS were you using? I'm running into the same issue. @Leon Laude I have a Windows 11 Pro Gen 2 with Standard D4s v3. The Hyper-V option enabled but also could not start due to the same reason.

@Christopher Isidora I am also using Window 11 (Windows 11 Enterprise 64-bit, 10.0 Build 22000) did you somehow managed to get it working?

@Leon Laude Do you have any suggestion what to do else? I am on a Standard D4ds v4 machine, which also should support nested virtualization.

This is important

[https://learn.microsoft.com/en-us/answers/questions/1314633/not-able-to-run-wsl2-on-an-azure-vm-(standard-d8s](https://learn.microsoft.com/en-us/answers/questions/1314633/not-able-to-run-wsl2-on-an-azure-vm-(standard-d8s)

If you are creating new azure vm, use the recommended size most important when deploying VM set security to 'Standard' instead of ‘Trusted Launch’
