9.18.9.6. Assigning a vGPU to a VM by using the CLI

Prerequisites

• The mediated device is configured in the HyperConverged custom resource.
• The virtual machine (VM) is stopped.

Procedure

• Assign the mediated device to a VM by editing the spec.domain.devices.gpus stanza of the VirtualMachine manifest.

  Example virtual machine manifest:

  apiVersion: kubevirt.io/v1
  kind: VirtualMachine
  spec:
    domain:
      devices:
        gpus:
        - deviceName: nvidia.com/TU104GL_Tesla_T4
          name: gpu1
        - deviceName: nvidia.com/GRID_T4-2Q
          name: gpu2

  • spec.template.spec.domain.devices.gpus.deviceName specifies the resource name associated with the mediated device.
  • spec.template.spec.domain.devices.gpus.name specifies a name to identify the device on the VM.

Verification

• To verify that the device is available from the virtual machine, run the following command, substituting <device_name> with the deviceName value from the VirtualMachine manifest:

  $ lspci -nnk | grep <device_name>
