cannot get WSL2 to work in Windows 11, that is virtualized inside of proxmox 8

Can you run the command: wsl —-status in order to verify from that screenshot it could be WSL 1.0.
I can get WSL 1 running but not WSL 2.

I initially had WSL1 as well. I ran the commands wsl --set-default 1 and wsl --set-default 2, and then it was fixed.

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.

i can confirm this breaks GPU passthrough :-(

confirmed.
13900hk es does not work.

win11
args: -cpu host,hv_passthrough,level=30,-waitpkg

work fine, 4090 passthrough also work

OMG this worked!!! AMAZING

If you are having this problem and you're anything like me, you might not even know what he means by this but its super simple so Ill give you some context.

In your host edit the config for your windows VM

nano /etc/pve/qemu-server/<vm-id>.conf
add the line that he posted to the bottom of the file (obviously if you already have an args line, you may need to edit it instead:

args: -cpu host,hv_passthrough,level=30,-waitpkg

Start VM up and viola!

I can confirm that on i9-13900K this works:

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

while this doesn't work:

args: -cpu host,hv_passthrough,level=30,-waitpkg

I didn't try GPU passthrough and it's disabled in my setup,

the PVE default emulated CPUs do not enable all necessary CPU features for the guest to run nested virtualization,
one has to fall back to HOST-CPU
