• install arch with sway the normal way

• install dependencies

sudo pacman -S git base-devel

git clone https://aur.archlinux.org/yay.git && cd yay && makepkg -si

• start sshd

sudo systemctl start sshd

• for nvidia:

mkdir drivers

• install https://github.com/dantmnf/WSLAttachSwitch on windows

• open command prompt as admin

WSLAttachSwitch.exe "Default Switch"

do now in WSL

sudo dhclient eth1

• copy proretary files

scp -r /usr/lib/wsl/lib arch-dxgkrnl:~/

• for nvidia:

ssh arch-dxgkrnl sudo -S mkdir -p $(echo /usr/lib/wsl/drivers/nvle.inf_amd64_*/)
scp -r /usr/lib/wsl/drivers/nvle.inf_amd64_*/*.so* arch-dxgkrnl:~/drivers

ssh arch-dxgkrnl

sudo mv lib/* /usr/lib
sudo ln -s /lib/libd3d12core.so /lib/libD3D12Core.so

• for nvidia:

sudo cp -r drivers/* /usr/lib/wsl/drivers/nvle.inf_amd64_*

• install dxg dkms

cd ~
git clone https://github.com/OlfillasOdikno/dxgkrnl-dkms.git && cd dxgkrnl-dkms && makepkg -si

sudo modprobe dxgkrnl

/dev/dxg should now exist

• install mesa-d3d12

yay -S mesa-d3d12 mesa-utils xorg-xwayland

Now in hyperv:

export MESA_LOADER_DRIVER_OVERRIDE=d3d12
export WLR_RENDERER_ALLOW_SOFTWARE=1
LIBGL_ALWAYS_SOFTWARE=1 sway

Now execute glxinfo in sway:

LIBGL_ALWAYS_SOFTWARE=0 glxinfo -B

It should show your graphics card

As far as I know it should work correctly, I have run AI programs like Ollama and Stable Diffusion/Riffusion and they work without errors/issues.

The containers provided by Nvidia should also work. However, I have not tested on my end.

I tend to prefer using SSH forwarding and use the apps webgui's through another machine.

If you have multiple nvidia cards in your host, you might need to pass all of them in order for nvidia-smi to function correctly.
