[ovs-discuss] OVS+DPDK on CentOS 7

[Nicolas Vazquez]

My mistake :)

Been checking the /var/run/openvswitch/ovs-vswitchd.log and found this is
the error:

2019-07-11T03:11:31.789Z|00226|netdev_dpdk|INFO|Socket
/var/run/openvswitch/test created for vhost-user port test
2019-07-11T03:11:31.790Z|00227|dpif_netlink|WARN|system at ovs-system: cannot
create port `test' because it has unsupported type `dpdkvhostuser'

I thought maybe DPDK was not being initialized properly but surprisingly
noticed these earlier in the logs:

2019-07-10T18:56:02.183Z|00039|dpdk|INFO|DPDK Enabled - initializing...
