Configure SR-IOV with OpenVSwitch¶

Neutron OVS requires enabling of the sriovnicswitch mechanism driver on the Neutron server side and the neutron-sriov-nic-agent running on each compute node with this feature enabled.

To configure SR-IOV with OpenVSwitch:

1. Include the class to cluster.<NAME>.openstack.compute:

   - system.neutron.compute.nfv.sriov
   

   Note

   By default, the metadata model contains configuration for 1 NIC dedicated for SR-IOV.

2. Include the class to cluster.<NAME>.openstack.control:

   - system.neutron.control.openvswitch.sriov
   

3. If you need more than 1 NIC, extend the previous configuration by extra Neutron cluster.<NAME>.openstack.compute.

   Example

   ...
     neutron:
       compute:
         backend:
           sriov:
             sriov_nic01:
               devname: eth1
               physical_network: physnet3
             sriov_nic02:
               devname: eth2
               physical_network: physnet4
             sriov_nic03:
               devname: eth3
               physical_network: physnet5
             sriov_nic04:
               devname: eth4
               physical_network: physnet6
