Hello, I am trying to connect testpmd to an OVS port. Port in OVS is created using the following command
ovs-vsctl add-port br0 vhost-user1 -- set Interface vhost-user1 type=dpdkvhostuser The command above creates the unix socket file /usr/local/var/run/openvswitch/vhost-user1. Then I launch testpmd as following export DPDK_PARAMS=" -l 3-4 --master-lcore 3 -n 1 \ -m 1024 --file-prefix testpmd --no-pci --log-level=8 \ --vdev=net_virtio_user1,mac=00:00:91:00:00:01, path=/usr/local/var/run/openvswitch/vhost-user1" export TESTPMD_PARAMS="--burst=64 -i --disable-hw-vlan --txd=2048 --rxd=2048 --forward-mode=io --auto-start --coremask=0x18" /usr/src/dpdk-17.11/x86_64-native-linuxapp-gcc/app# ./testpmd $DPDK_PARAMS -- $TESTPMD_PARAMS testpmd launches, however prompts the following error during loading vdev_probe(): failed to initialize net_virtio_user1 device Mar 12 15:29:54 tdev testpmd[7367]: EAL: Bus (vdev) probe failed. I don know if I set the debugging level right but I don't get further information about why the initialization fails. Any ideas? Thanks, Alan
