8.6.8. ovs_driver
The following table outlines the options available under the [ovs_driver] group in the /etc/neutron/plugins/ml2/ml2_conf.ini file.
| Configuration option = Default value | Type | Description |
|---|---|---|
|
| list value | Comma-separated list of VNIC types for which support is administratively prohibited by the mechanism driver. Please note that the supported vnic_types depend on your network interface card, on the kernel version of your operating system, and on other factors, like OVS version. In case of ovs mechanism driver the valid vnic types are normal and direct. Note that direct is supported only from kernel 4.8, and from ovs 2.8.0. Bind DIRECT (SR-IOV) port allows to offload the OVS flows using tc to the SR-IOV NIC. This allows to support hardware offload via tc and that allows us to manage the VF by OpenFlow control plane using representor net-device. |
