Description of problem:
https://access.redhat.com/documentation/en/red-hat-openstack-platform/9/paged/networking-guide/chapter-20-sr-iov-support-for-virtual-networking uses the approach which relies on neutron port-create ... --binding:vnic-type direct.

However, in some cases the pci_alias based approach might be more suitable; from http://docs.openstack.org/newton/networking-guide/config-sriov.html#configure-nova-scheduler-controller :

There are two ways to attach VFs to an instance. You can create an SR-IOV port or use the pci_alias in the Compute service. For more information about using pci_alias, refer to [...] http://docs.openstack.org/newton/config-reference/compute/config-options.html#id29 .
