13.2. Configuring vGPU on the Compute nodes

To enable your cloud users to create instances that use a virtual GPU (vGPU), you must configure the Compute nodes that have the physical GPUs:

  1. Prepare the GPU role, profile, and flavor for designating Compute nodes for vGPU.
  2. Configure the Compute node for vGPU.
  3. Deploy the overcloud.
ヒント

If the GPU hardware is limited, you can also configure a host aggregate to optimize scheduling on the vGPU Compute nodes. To schedule only instances that request vGPUs on the vGPU Compute nodes, create a host aggregate of the vGPU Compute nodes, and configure the Compute scheduler to place only vGPU instances on the host aggregate. For more information, see Creating and managing host aggregates and Filtering by isolating host aggregates.

注記

To use an NVIDIA GRID vGPU, you must comply with the NVIDIA GRID licensing requirements and you must have the URL of your self-hosted license server. For more information, see the NVIDIA License Server Release Notes web page.

13.2.1. Prerequisites

  • You have downloaded the NVIDIA GRID host driver RPM package that corresponds to your GPU device from the NVIDIA website. To determine which driver you need, see the NVIDIA Driver Downloads Portal. You must be a registered NVIDIA customer to download the drivers from the portal.
  • You have built a custom overcloud image that has the NVIDIA GRID host driver installed. For more information about building a custom overcloud image, see Working with overcloud images.
