 Once the setup is complete, you can follow the [general steps]({{% relref "pci_passthrough#pci-config" %}}) for adding PCI devices to a VM. For NVIDIA GPUs, please consider the following:
 
 - OpenNebula supports both the legacy mediated device interface and the new vendor-specific interface introduced with Ubuntu 24.04. The vGPU device configuration is handled automatically by the virtualization and monitoring drivers. The monitoring process automatically sets the appropriate mode for each device using the `MDEV_MODE` attribute.
-- The NVIDIA vGPU configuration is based on a profile which defines the vGPU’s characteristics and hardware capabilities. This profile is retrieved from the drivers by the monitoring process, allowing you to select the one that best suits your application’s requirements. When using MIG, each MIG instance you created appears as a separate vGPU profile.

 When using NVIDIA cards, ensure that only the GPU (for PCI passthrough) or vGPUs (for SR-IOV) are exposed through the PCI monitoring probe. Do not mix both types of devices in the same configuration.{{< /alert >}}
