I just wanted to let anyone know that I have successfully tested Nvidia GPU-P on Windows on unRAID with an RTX3060 passed though.

 

I used this guide video. 

 

 

Also WSL2 works with my intel 10700K  and  Gigabyte Z490 VISION G

WSLg works, but not with hardware acceleration. I wonder why that could be?

Works bare metal with the same Windows 11 installation

Hi,

 

I read this thread and i was wondering how you have managed it. So you are saying that you have succesfully shared a gpu in windows on unRaid?

So unRaid > Windows VM > Hyper-V > Windows VM inside Hyper-V?

I am trying to achieve the same, but with no luck. The VM inside Hyper-v just gives me a black screen.

 

Can you share how you have managed it?

Yes, the nested VM's are as you said. I used the video guide I linked in my last message. Very roughly I used Windows 11  for both VM's, inner and outer.  Passthrough the GPU to the outer.

 

You first issue the PS commands in the Win host VM that are mentioned in the video to tell if you're GPU is suitable (which it probably is because there is broad support). Then you install the hyper-v VM with all the settings like in the video.

 

The most crucial part, though is that you have to copy over your exact Graphics Driver file set for the installed GPU (driver) from the outer to the inner Windows and place them all in the right dirs. This is explicit in the video. Using the inner vM's drivers, installed or otherwise will not work.

 

Then you run the included script in the Youtube description and start the VM and voila! GPU acceleration in a nested VM

Hi, I've tried on several different versions of windows (10 & 11) and also different versions of unraid to achieve the same.  

 

But every time i enable Hyper-V within my "Windows features" all my VM's get stuck at the windows spinning loading screen as it seems most others are stuck at too on forums.

 

Baremetal my Windows Install loads up without a problem but when put through unraid it doesn't.

 

Would you mind posting which version of unraid you are using and the template you are using for your successful unRaid > Windows VM ?

 

Many Thanks

 

Subbing as I have the same problem. Enabling VM platform/Linux subsystem results in failure to boot, have to boot in safe mode from recovery where it reverts the changes before it can boot again.

Have you added nested kernel option in syslinux? Tbis is for intel

label unRAID OS

  menu default

  kernel /bzimage

  append initrd=/bzroot kvm_intel.nested=1

 

AMD. kvm_amd.nested=1

Oh didn't know about that, sounds like it'd help

Will add for next reboot...

Tried, but still same

 

it does show as enabled:

sadly I'm getting the same result even after enabling the AMD equivalent for me kvm_amd nested=1 / kvm_amd.nested=1

 

still a spinning windows boot screen

I had this working in unRAID 6.10.0-rc1. Since then I only run my windows VM bare metal because the WSL2 performance is like night and day. Anyway, here is my XML

 

It says Winndows 10 but it's actually Windows 11. Yes enabling nested=1 was necessary
