Not able to run WSL2 on an Azure VM (Standard D8s v3 (8 vcpus, 32 GiB memory)) -

Mike Hingley 5

I span up a VM to run some workload using WSL2. I have previously had similar machines and had no problems setting up WSL2 - but for some reason, attempting to run WSL throws the following error :
Error Message from VM - Please enable the Virtual Machine Platform Windows feature and ensure virtualization is enabled in the BIOS.

The Virtual Machine Platform feature is enabled - yet I still get the error - which I understand is due to the VM not supporting Nested Virtualisation - however I believe this machine is supposed to support this :
Details of DSv3 machines

Anyone got any ideas what I've done wrong here?

@Mike Hingley

I can see you are getting the error on your Azure VM:

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

Likely the issue you are facing is that Trusted Launch needs to be disabled. Currently Trusted Launch does not support Nested Virtualization. When launching your VM please set the Security Type to Standard, currently the portal enables Trusted Launch by default.

To verify that it works I launched Standard D8s v3 VM and enabled WSL 2 following the instructions here. Launched Powershell and ran "wsl --install".

After Reboot: enter image description here

Hope this helps! Let me know if that is not the issue and we can work with you directly to troubleshoot.

thanks @deherman-MSFT - I think that might be the answer - I can see the security mode is set to Trusted Launch on the machine overview. Had no idea that would affect it - but now I know. I'll have a go a switching that, and trying again.

Hey @deherman-MSFT - I can't find thatthen when I select Windows 10 from the Image, the security type is reset to Trusted. If I then change that to standard, then the image is cleared. So I'm not sure how you could create a machine on Azure of that size, if the create a virtual machine page prevents you from doing so.

When I try an launch the VM, I can find no option to set the security type - just a Start button.

@Mike Hingley I do see that once you select the image that the Security type gets reset to Trusted Launch. However, I am able to change the Security Type once the image is selected and it does not reset anything. Can you confirm the image you are using?
