Repro Steps

I set the network type to mirrored in the .wslconfig file.
networkingMode=mirrored
and then restart WSL

Expected Behavior

Everything's getting good. It should work.

When I start wsl it reports an error:

Is there a available solution yet, please? I found in the Microsoft documentation that it might mean HCN_E_REQUEST_UNSUPPORTED error which is "The specified request is unsupported". I am hosting my virtual machine in azure, hope this helps!

Hi there. can you clarify what version of Windows is running in your virtual machine? Is this a server SKU? is it a headless server SKU? I'm reading code where it looks like it's blocking it for some reason.

[ecomter]

It's Windows Server 2025 Datacenter Azure Edition Build 26052 running on Microsoft Azure, I connect to it by RDP. So I think it is a Headless server SKU

[keith-horton]

Yeah, sorry. I found code in another component that's blocking Mirrored mode from running on Server SKUs :(

I'm going to try and fix this for the next release. I will have to pitch this to folks who work on servicing for existing releases.

Hi @keith-horton , just a friendly ping to see if you were able to get Mirrored mode working with Windows Server (2022 in particular) and if there's any eta on the release for the next WSL pre-release build. Thanks!

I'm also getting this on Windows Datacenter Server 2025 preview.
