Windows 11 WSL2 is not supported with your current machine configuration

SethNY

XCP-ng 8.3, XO from sources.
Created Win11 from ISO using the built-in Windows 11 template
Configured and turned into template for cloning.

Trouble installing WSL on the cloned Win11:
WSL2 is not supported with your current machine configuration

This worked a couple years ago Win10 on XCP-ng 8.2, Ubuntu 22.04.

From administrative powershell

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
(Accept the reboot, back to administrative powersehll)
wsl --install
(fails)
wsl --list --online
wsl --install -d Ubuntu-24.04
(fails again)

I tried enabling Nested Virtualization for the VM without success
Booted to (F2) BIOS and confirmed not virtualization options there to enable

Has anyone got Win11/WSL/8.3 working? I'm hoping it's not due to not installing a Windows license key.

Error code: Wsl/InstallDistro/Service/RegisterDistro/CreateVm/HCS/HCS_E_HYPERV_NOT_INSTALLED

Additionally tried this:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

EDIT: Add Next steps tried
Open the Turn Windows features on or off panel
Turn these settings off: Hyper-V, Windows Subsystem for Linux, Virtual Machine Platform, click OK, and restart your computer.
Turn these settings ON: Hyper-V, Windows Subsystem for Linux, Virtual Machine Platform, click OK, and restart your computer.

EDIT2:
dism.exe /online /get-features /format:table
HypervisorPlatform was disabled
Enable Windows Hypervisor Platform feature and rebooted.

This did not fix the issue.

EDIT3:
It looks like WSL on Windows 11 might be unsupported on XGP-ng 8.3

You were probably using WSL 1 before, and now using WSL 2 (which requires Hyper-V thus nested virtualization). And I'm not aware of WSL 2 working on XCP-ng 8.2, I assume you were actually using WSL 1 previously.

You can use WSL 1 by using

wsl.exe --set-default-version 1

and

wsl.exe --set-version <Distro> 1

@TeddyAstie you give me the answer and a valid workaround. You rock!

Confirmed that solved my issue, as WSL 1 is fine for me to run Ansible.
