Changing the Interface Type to SR-IOV

For instance types that support Enhanced Networking, you can change the interface type from Xen-PV to SR-IOV. The interface type applies to all interfaces for this instance.


After you set the interface type to SR-IOV, you cannot change the instance back to the Xen-PV interface type.

To change the interface type, you use CLI tools installed on a separate host. The CLI tools cannot be on the same host as the instance being modified.

To change the interface type to SR-IOV:

  1. Shut down the instance being modified.
  2. Execute the following commands on a Ubuntu host.

    For example:

  3. Start the instance with SR-IOV network interfaces.
