Symptoms

Identified Symptoms

The xorg service fails to start when using pci-passthrough after installing the NVIDIA GPU VIB file.

The output of the command to check the xorg stats indicates that the service is not running.

/etc/init.d/xorg status

The output shows:

Xorg is not running

Also, the command "nvidia-smi" fails.

nvidia-smi

Running the command to list the PCI devices shows the ModuleName as "pciPassthru" instead of the expected "Nvidia" for the NVIDIA devices.

esxcli hardware pci list -c 0x0300 -m 0xf

The output includes:

ModuleName: pciPassthru

Instead of the expected:

ModuleName: nvidia

Cause

 This issue occurs when you pass all cores using pci-passthrough at the host level even if they are not being used in a virtual machine.

Resolution

Resolving the xorg Service Failure

To resolve the issue with the xorg service failing to start when using pci-passthrough, follow these steps:

  • Navigate to the vSphere web client
  • Select the host --> Hardware --> PCI Devices --> Click edit (in vSphere client, you find the configure passthrough button in the upper right corner)
  • Change the status of all the NVIDIA devices to "Unavailable" (or at least one of them)
  • Navigate then to host --> Hardware --> Graphics
  • Confirm that the graphics type is "Shared direct" and not just "Shared"
  • After that select the host --> configure --> system --> security profile --> services --> xorg
  • Click edit, and select Start and stop with host and then click ok
  • Put the node into maintenance mode and make sure all the VMs are migrated
  • Reboot the node

The xorg service should be running after these steps. You can verify this by running the following commands:

/etc/init.d/xorg status
nvidia-smi

These commands should show that the xorg service is running and the NVIDIA GPU is recognized, respectively.
