You must modify the metadata for an image to enable SR-IOV. All instances created from a SR-IOV-enabled flavor and SR-IOV-enabled image inherit the SR-IOV property.

Procedure

  1. Log in to the VMware Integrated OpenStack dashboard as a cloud administrator.
  2. Select the admin project from the drop-down menu in the title bar.
  3. Select Admin > System > Images.
  4. (Optional) : Create an image definition dedicated to the SR-IOV specification.

    The original image configuration remains intact and available for other uses.

  5. Select the image to modify.
  6. In the Actions column of the image listing, click the down arrow and select Update Metadata.
  7. In the column under Available Metadata, expand the VMware Driver Options tab.
    Note:

    If the VMware Driver Options tab is not present, the related metadata property might already be configured.

  8. Click the plus sign (+) next to the Virtual Network Interface metadata property.

    In the column under Existing Metadata, the newly added metadata property appears as hw_vif_model.

  9. From the drop-down list, select VirtualSriovEthernetCard.
  10. Click Save.
