When I enable wsl2 through windows platform, win11 vm immediately starts to boot into advanced recovery console. Any advice?

I run Windows 11 as vm inside of proxmox 8. I successfully set gpu passthrough, and I am able to run Nvidia GPU inside of Win11. I can run games, furmark etc.
But when I try to run "Ubuntu" WSL2 in Windows, I get an error

Code: 
WslRegisterDistribution failed with error: 0x80370102
Please enable the Virtual Machine Platform Windows feature and ensure virtualization is enabled in the BIOS.

As soon as I enable Virtual Machine Platform in Windows Features, windows stops to boot and immediately falls into Advanced Recovery Mode during startup. The only way to get it back is to manually load vsscsi driver there and then usebcdedit /set hypervisorlaunchtype off to disable hyperv/windows virtualization.

I went through many tutorials/forums. Already tried -kvm arg in vm configuration, tried hidden=1 in various combinations. The result is the same all the time.

I understand that I can easily create another VM on host proxmox and ssh there, but I still would like to have ability to run WSL.

I have to be that guy and ask (assuming this is latest win11 and not some tarted about custom version)
you did run wsl --install right? - it is telling you the platform components are not installed.... if you did what does wsl -v and wsl --status show

This is with disabled hyperv, as otherwise it doesn't boot
 
oh, then you don't have a WSL issue - you have a hyper-v issue, you need to fix that issue first before you tackle wsl

you need hyper-v to use WSL2

I assume you are using pro if you can control separately if hyper-v is installed -

you have a lot going on in that win11 vm (passthrough, the extra vmx flag etc) i would suggest you pare it back down to a basic win11 with disks, network card, no pass through devices, just defalt display adpate, host CPU and nested virtualization, etc and start that there - might be worth spinning up a win 11 VM fresh using only UI options in pve...

i can test on my pve8 tomorrow (it is 10pm here)

yup something very funky in latest win11 GA - added vmx=on as recommended by kvm site - the machine then boots but the event logs complain that vmx is not supported and issues with signing

and in the event logs we get Hypervisor launch failed; Either VMX not present or not enabled in BIOS. this would seem to be an issue with the UEFI BIOS maybe? as PVE is new to me, i am not sure what should and should not work

but there is a post around here where someoene hit the issue with win10, another post on reddit where someone hit this installing docker (which installs hyper and on wsl).

something seems broken IMO
 
oh i tried that, old q35 types, mixes of CPUS - i note we are using a debian unstable OVMF, maybe we need a later one
@fiona i notice you are mentioned in the notes for edk2 2023.02-1 in trixie - are we all going mad (there are multiple posts about this this month) or is win11 nested virtualization currently broken on Win11 with all august windows patches?

(or are we all just stupid and missing something obvious)

It seems like an issue with Windows 11 and PVE... I have been trying to get the exact same setup but was unsuccessful.

The only way I could get WSL2 setup correctly on a Windows 11 VM in PVE is to disable GPU passthrough AND add the following to my config:

Code: 
args: -cpu Cooperlake,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time,+vmx
cpu: host

Setting the CPU type to Cooperlake disables the ability to do GPU passthrough of the Intel Iris XE onboard graphics in my case. So I cannot enable both GPU passthrough and WSL2 on the same VM.

I can confirm this worked for me.

work fine, 4090 passthrough also work

Have you tried passing through integrated Intel Graphics? This above works in getting the VM to boot to the Windows Desktop but you get the Error 43 message for the Intel Iris XE graphics and the OS doesn't list the GPU in Task Manager.

Just following up, whenever the Virtual Machine Platform Windows Feature is enabled I get the Error 43 message. When that feature is disabled the GPU will be recognized.

Microsoft is using Hyper-V technology for an ever increasing number features in Windows, including security hardening I/O. So you can quickly run with an extra nesting layer without knowing.

And naturally it doesn't care about compatibility with other hypervisors than its own: why have anyone else feed from the trough that they consider natuarlly their own when you happen to run a bit of their software?

So co-existance of WSL with any of those other hyper-V enabling features might be managed by Microsoft, but triple-nesting or some type of side-by-side coordinated nesting, most likely won't.

I learned the hard way coming from VMware workstation, which uses its own type-2 hypervisor normally and has more features and capabilities than Hyper-V. But as soon as Microsoft enables Hyper-V, VMWare workstation has to step back and use Hyper-V instead, which can be ok, unless you depend on VMware hypervisor features...

Just finding out what's going on and fixing this afterwards has cost me precions days of my life...

Sorry, I don’t have passthrough to Intel graphics
