 If IOMMU wasn’t enabled on the host, follow the process specified in the official documentation to enable IOMMU - https://docs.opennebula.io/7.0/product/cluster_configuration/hosts_and_clusters/nvidia_gpu_passthrough/.
 At the next step GPU has to be bound to the vfio driver. For this, perform the following steps:
-1. Install `driverctl` utility:

-4.  Set the driver override. Use the PCI address from the previous step to set an override for the device to use the `vfio-pci` driver.
+3. Set the driver override. Use a driverctl utility and the PCI address of the GPU device from the previous step to override driver.

     Check that the GPU is now using the `vfio-pci` driver.
