Check the /var/run/usvhost . Do you have the socket created there ? Is that
visible from docker.
Sometime back when I used a container, I passed a mac address for DPDK
Parameters when starting the dpdk test_pmd application in container.

Hi DPDK Users,
I am trying to use docker container and ovs(2.6.0)-dpdk(16.07) to setup a
test. I want to setup two docker containers, each of them will use a virtual
device (socket) created by the ovs-dpdk. The final purpose would let the two
containers talk to each other.
Setup ovs-dpdk
1. ovsdb-tool create $ovs-dir/etc/openvswitch/conf.db
$ovs-dir/share/openvswitch/vswitch.ovsschema
2. ovsdb-server --remote=punix:$ovs-dir/var/run/openvswitch/db.sock
--remote=db:Open_vSwitch,Open_vSwitch,manager_options --pidfile --detach
3. ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true
4. ovs-vsctl --no-wait set Open_vSwitch .
other_config:dpdk-socket-mem="512,512"
5. ovs-vswitchd unix:$ovs-dir/var/run/openvswitch/db.sock --pidfile
--detach --log-file=$ovs-dir/temp.log
Setup bridge and ports
1. ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev
2. ovs-vsctl add-port br0 vhost-user1 -- set Interface vhost-user1
type=dpdkvhostuser ofport_request=1
3. ovs-vsctl add-port br0 vhost-user2 -- set Interface vhost-user2
type=dpdkvhostuser ofport_request=2
4. ovs-ofctl add-flow br0 priority=1000,in_port=1,actions=output:2
5. ovs-ofctl add-flow br0 priority=1000,in_port=2,actions=output:1
Run the docker container
1. docker run -it --privileged -v
$ovs-dir/var/run/openvswitch/vhost-user1:/var/run/usvhost -v
/mnt/huge/:/dev/hugepages/ $docker-image bash
Run the dpdk application in the docker container
1. $dpdk-app -c 0x01 --socket-mem=128,0
--vdev=virtio_user0,path=/var/run/usvhost --file-prefix="docker1"
However, I encountered this error
PMD: vhost_user_setup(): connect error, Connection refused
PMD: virtio_user_dev_init(): backend set up fails
PMD: virtio_user_pmd_devinit(): virtio_user_dev_init fails
EAL: failed to initialize virtio_user0 device
It seems like the application in the docker container cannot connect the
socket created by the ovs-dpdk.
Can anybody please help me and point out some possible solutions? Looking
forward to your reply. Thanks very much for your help.
Best wishes,
Xiaoban
