Windows 11 wsl2 does not work

[lordsnoake]

Hello,
I have been having issues with windows 11 wsl2 working under proxmox.
I am fairly new so i am just going to go based off on the threads that i saw of the information that i might be asked for.

This is the configuration from my vm. I added the args based on another thread that i saw that i thought might helped but unfortunately it did not.
This is the thread https://forum.proxmox.com/threads/cant-get-wsl2-to-work-on-win11-under-proxmox-7-2-ve.115582/
I also followed the nested virtualization guide (https://pve.proxmox.com/wiki/Nested_Virtualization) but no avail as well

args: hv_relaxed,hv_vapic,hv_spinlocks=0x1fff,hv_vpindex,hv_runtime,hv_crash,hv_time,hv_synic,hv_stimer,hv_tlbflush,hv_ipi,hv_reset,hv_frequencies...

Any help or a guide is greatly appreciated.

HI, what issues exactly are you having with wsl?

From your config it looks like you didn't set scsi as the drive controller. Did you follow the windows 11 best practices [1]? And did you install the VirtIO drivers? If not, maybe create a new vm following the best practices and test if wsl works then. (Don't forget to set the cpu to `host`, I don't think that's in the best practice guide). Don't bother setting the extra args in your conf for now.

Also, did you install wsl correctly? You need to run wsl --install as admin in powershell, then reboot and download whatever linux distro you want from the microsoft store. If it errors at first and tells you to activate something or other, google the error; you might need to change some windows settings.

Best of luck

PS: I don't know how much ram your host has, but if you want to use 32 GiB ram you want 32768 MiB not 32000, see [2].

Thanks, i was able to get it resolved

glad to hear
would you mind sharing what exactly the problem was and how you fixed it for other users who might find this thread?

WSL2 needs nested Virtualization.

i just followed the guide from the start

The following run as admin user in cmd worked for me on win11 wsl2 for ubuntu

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
