```
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:

```default
# dnf install driverctl
```

2. Ensure `vfio-pci` module is loaded on boot:
1. Ensure `vfio-pci` module is loaded on boot:

```default
# echo "vfio-pci" | sudo tee /etc/modules-load.d/vfio-pci.conf
# modprobe vfio-pci
```

3. Identify the GPU's PCI address:
2. Identify the GPU's PCI address:

```default
# lspci -D | grep -i nvidia
0000:e1:00.0 3D controller: NVIDIA Corporation GH100 [H100 PCIe] (rev a1)
```

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.

```default
# driverctl set-override 0000:e1:00.0 vfio-pci
```

5. Verify the driver binding:
4. Verify the driver binding:
Check that the GPU is now using the `vfio-pci` driver.
