DPDK Support in OVN

Configuration Settings

The following configuration parameter needs to be set in the Neutron ML2 plugin configuration file under the ‘ovn’ section to enable DPDK support.

vhost_sock_dir

This is the directory path in which vswitch daemon in all the compute nodes creates the virtio socket. Follow the instructions in INSTALL.DPDK.md in openvswitch source tree to know how to configure DPDK support in vswitch daemons.

Configuration Settings in compute hosts

Compute nodes configured with OVS DPDK should set the datapath_type as “netdev” for the integration bridge (managed by OVN) and all other bridges if connected to the integration bridge via patch ports. The below command can be used to set the datapath_type.

$ sudo ovs-vsctl set Bridge br-int datapath_type=netdev
