Configure PCI-Passthrough Interface to NVIDIA GPU in a VM
|
|
=========================================================
|
|
|

This section provides instructions for configuring PCI-Passthrough interface
|
|
to NVIDIA GPU Operator in a |VM|.

#. Check the **conf.nova.pci.alias.values** override. If your graphics
|
|
card alias exists, for example, **"name": "nvidia-tesla-t4-vf"**,
|
|
check if the values in step, 2.b., are correct and proceed to step 5.
|
|
If the values do not exist or are incorrect, update the Nova Helm
|
|
overrides.
|
|
|
|
#. Create a file containing the current **conf.nova.pci.alias.values**
|
|
overrides and add the following additional entry in the values
|
|
array for the NVIDIA device based on the values from step 2.b.,
|
|
for example:
|
|
|
|
.. code-block:: none
|
|
|
|
'{"vendor_id": *<vendor_id>*, "product_id": *<product_id>*, "device_type": "type-PF", "name": "nvidia-tesla-t4-pf"}'
|
|
|
|
Where
|
|
|
|
*<vendor_id>* is the ID of the vendor
|
|
|
|
*<product_id>* is the ID of the product
|
|
|
|
#. Save the **.yaml** file.

.. note::
|
|
8 GB RAM, 4 VCPUs, and large memory page size are example values
|
|
for GPU drivers' system requirements. For valid system requirements for
|
|
GPU drivers, see, `https://www.nvidia.com/en-us/geforce/drivers/ <https://www.nvidia.com/en-us/geforce/drivers/>`__.

|
|
|
#. In OpenStack, create a |VM| and test access to the NVIDIA GPU device.
|
|
|
|
#. Create a new |VM|, using the newly created flavor in step 5.
|
|
|
|
#. In the |VM|, install and test the CUDA drivers.
