11.3. Creating the vGPU image and flavor

To enable your cloud users to create instances that use a virtual GPU (vGPU), you can define a custom vGPU-enabled image, and you can create a vGPU flavor.

11.3.1. Creating a custom GPU instance image

After you deploy the overcloud with GPU-enabled Compute nodes, you can create a custom vGPU-enabled instance image with the NVIDIA GRID guest driver and license file.

Procedure

  1. Create an instance with the hardware and software profile that your vGPU instances require: 

    (overcloud) [stack@director ~]$ openstack server create --flavor <flavor> --image <image> temp_vgpu_instance
    • Replace <flavor> with the name or ID of the flavor that has the hardware profile that your vGPU instances require. For information on default flavors, see Manage flavors.
    • Replace <image> with the name or ID of the image that has the software profile that your vGPU instances require. For information on downloading RHEL cloud images, see Image service.
  2. Log in to the instance as a cloud-user. For more information, see Log in to an Instance.
  3. Create the gridd.conf NVIDIA GRID license file on the instance, following the NVIDIA guidance: Licensing an NVIDIA vGPU on Linux by Using a Configuration File.

  4. Install the GPU driver on the instance. For more information about installing an NVIDIA driver, see Installing the NVIDIA vGPU Software Graphics Driver on Linux.

    注記

    Use the hw_video_model image property to define the GPU driver type. You can choose none if you want to disable the emulated GPUs for your vGPU instances. For more information about supported drivers, see 付録A Image configuration parameters.

  5. Create an image snapshot of the instance: 

    (overcloud) [stack@director ~]$ openstack server image create --name vgpu_image temp_vgpu_instance
  6. Optional: Delete the instance.
