To use the SR-IOV feature, make sure that your Cloud meets the following requirements:

Virtual functions can be created for the NICs at the hardware level.
The Intel VT-d and SR-IOV are enabled in the BIOS settings.
In the Cloud, the IOMMU State of the corresponding host is enabled.
Note: After you change the IOMMU State of a host, you need to restart the host for the change to take effect. You can check the state via the IOMMU Status.
