Primary GPU for Windows 10 VM - Error Code 43

[Luke Sutherland]

Attempting to configure primary GPU (GTX1650 Super) into a windows 10 templated VM. I have so far:

 

Mapped the 4 inputs of the GPU via binding VFIO

Uploaded and edited the NVDIA header from the ROM file 

Edited the XML file to add the Multiformat command and iterated the 4 slots

 

I have tried multiple times to configure via advice given by these forums and YouTube via SpaceInvaders. 

 

Any support would be so greatly appreciated.

 

Windows 10.xml vfio-pci.cfg TU116.rom GTX1650 Super TU116 4.1.2022.rom

Try this in your xml file:

 

<features>
    <acpi/>
    <apic/>
    <hyperv mode='custom'>
      <relaxed state='on'/>
      <vapic state='on'/>
      <spinlocks state='on' retries='8191'/>
      <vendor_id state='on' value='1234567890ab'/>       <----  with Vendor ID set to 'none' you get error 43
    </hyperv>

    <kvm>
      <hidden state='on'/>     <--- set this for kvm, if you do not do it, you get error 43
    </kvm>

  </features>

SOLVED - Found a forum post that solved the issue along with a few other tweaks - I followed the following:

 

Spaceinvaders tips on the editing the XML file to include the multifunction='on'

 

ran the script via console:

 

echo 0 > /sys/class/vtconsole/vtcon0/bind
echo 0 > /sys/class/vtconsole/vtcon1/bind
echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbind

 

Allowed VFIO allow unsafe interrupts in Settings > VM Manager

 

Hope this helps!
