UNRAID + GTX 1080 + passthrough = UNSOLVABLE PROBLEM ?!?


Recommended Posts

Thank you for your answer ! My motherboard is an ASUS Gaming Motherboard – Z170 PRO GAMING and indeed there is a graphics chipset...

My VM works but if I try to put the drivers for my GTX 1080 the VM crashes and I get code 43

Hi,

 

I owned lots of GTX 1080 and none of them was incompatible. I'd say with GTX 1080 / GTX 1080 Ti I had zero issues on passthrough.

 

Did you follow the instructions on GPU passthrough precisely ? Do you have these lines in your VM configuration ?

 <features>
    ...
    <hyperv mode='custom'>
      ...
      <vendor_id state='on' value='1234567890ab'/>
      ...
    </hyperv>
    <kvm>
      <hidden state='on'/>
    </kvm>
    ...
  </features>

 

Also if this the only GPU in your system try putting this onto boot line:

video=efifb:off

Nobody in my case ?

Please review the great instructions for GPU pass through here:  Take notice of the BIOS changes that are necessary. Take notice of the Custom ROM/DUMP. https://www.techpowerup.com/vgabios/?architecture=NVIDIA&manufacturer=KFA2&model=GTX+1080&interface=&memType=&memSize=&since=

Take notice of the Binding needed.
