GPU Pass through


Recommended Posts

I have a GIGABYTE NVidia GT 1030 it is not my Primary Graphics for Unraid , I am using the buildit card for unraid.

 

I Have both the Card and Audio devices from the card in the same IMMO group.

I have followed space invaders video to edit the XML to make sure they are set for Multifunction in the same SLOT

I have tried this with both HyperV support in and out.

I am using OVMF (I have the same problem in SeaBios)

 

When I try to install the drivers I get

 

Windows encountered a problem installing the drivers software for your devices. I see nothing in windows event log about Error 43 . The drivers have never installed. Any help would be appreciated.

 

here is my XML

First and foremost, when copy-paste text from Unraid, please use the forum code functionality (the </> button next to the smiley button) so the code is sectioned and formatted correctly. It's incredibly hard to read codes when it's all exactly the same.

 

Yours is classic case of error code 43 so:

 

Did you check that your server actually boot with the onboard graphics? i.e. have you plugged a monitor to the ONBOARD display output e.g. VGA and make sure you see the Unraid command prompt in the output? Conversely, if you connect the display to the 1030, do you see nothing at boot?

It's not uncommon to unknowingly boot with the wrong card.

 

Next, please create a new VM template with OVMF + Q35 machine type + Hyper V On + everything else the same and see if it works.

If it doesn't copy-paste the xml here please (see point above about using the </> button).

 

Also copy-paste the PCI Devices section of Tools -> System Devices (again, </> button)

 

Also please attach diagnostics. Tools -> Diagnostics -> attach whole zip file.

@XiuzSu Where do you got that Windows Iso from? From the naming it looks like a modified version. You can bake in drivers into an ISO and maybe the one which is included has some issues. For example a guy a couple days ago had issues installing a newer Nvidia driver into a 1809 Windows install. If the author of that image used an old image with newer not supported drivers this might can be your issue. Try it with an up-to-date ISO directly from Microsoft.
