[ovs-discuss] 答复: Making an ovs rpm with dpdk, but after installing the rpm , there's no --dpdk parameter in ovs-vswitchd process; Why

[lifuqiong]

Thank you for your helpful reply.

I know how to start ovs with enable-dpdk manual,  do you mean there is no way to start ovs service with enable-dpdk with rpm install? Because I can not append parameter to ovs-vswitchd when I typed 'systemctl start/restart openvswitch'.

Thank you

The spec change is only about building OVS with DPDK support, configuring it to use is a different and more complicated topic.

With OVS 2.5, you'll need to start ovs-vswitchd manually with --dpdk and whatever options you need. Refer to INSTALL.DPDK.md for details.
In OVS 2.6 it'll be more integrated and controllable through db options.
