No VGA Output (Nvidia)

[PeteyBoPetey]

Hi Guys,

 

I am completely stumped. Had 3 VMs running flawlessly on Unraid 6.9. Did a clean install to 6.10.2 with the exception of copying super.dat and plus.key to my config folder. Created a VM like I have a million times before ....and................nuttin, nudda, ziploa. I have:

Used the previous vdisks with a Windoze 10 installed
vbios with the nvidia header removed
Added multifunction='on' after the vbios line in the xml
Changed all functions 0,1,2,& 3 to the same PCI slot

 

The VMs work when I set them up VNC. Also I note that one core is constantly pegged at 100% 

What have I forgotten?

TIA

Did you also remember to isolate the GPU from the OS via Tools - System Devices?

I bind to the vfio if that's what you mean?

 

 

 

I found this error in the VM log

Try to add also the other components of the gpu to the vm, replace this:

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x65' slot='0x00' function='0x0'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0' multifunction='on'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x65' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x1'/>
    </hostdev>

with this:
