Clarification for use of x-pci mentioned in the Google Docs Wiki #64

Closed thatsysadmin closed 2 years ago

thatsysadmin commented 3 years ago

In the OpenGL instabilities section of the Google Doc Wiki that was written by @KrutavShah, it says:

“The other solution is to “spoof” the vGPU to a normal Quadro, such as a Quadro P4000 for example with the x-pci arguments for the mediated vGPU device in the virtual machine configuration. “

Is there an example of a VM .xml file anyone can share to help me configure this? Thanks!

Yes and no - it depends on os/packages used. But xml does sound like libvirt and for that there is a guide in the discord server

For Libvirt you can use my guide: https://discord.com/channels/829786927829745685/830520513834516530/872802747727106119

But in short:

as dec

    <qemu:arg value="-set"/>
    <qemu:arg value="device.hostdev0.x-pci-device-id=6960"/>

or as hex

    <qemu:arg value="-set"/>
    <qemu:arg value="device.hostdev0.x-pci-device-id=0x1b30"/>

Fallowing are key requirements to work:

  1. Clean Windows - safe mode and ddu uninstaller clean is enough a) make snapshot before or clean up (DDU) after every try for best results!
  2. Install/Try install the Quadro drivers download from NV page IMPORTANT: Driver version does matter and you may have to try out some different drivers out before you have success! Or look in successful-setups if a poster has your GPU and look what he did - maybe you'll find the right driver version there and know also the right device to spoof to.
