[dpdk-dev] Docker container OVS-dpdk: vhost_user_setup(): connect error

[Deepak Gowda <deepak.dt06@gmail.com>]

Hi,

I'm trying to run test-pmd with this virtual devices created by the
ovs-dpdk from inside a docker container.
I see EAL probing failing every time, i did try restarting the ovs, no luck.
I see these vhost-user ports created from the log, i do see these from the
'ovs-vsctl show'.
Can't seem to figure out whats going wrong here,

EAL: Detected 4 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Probing VFIO support...
vhost_user_setup(): connect error, Connection refused
virtio_user_dev_init(): backend set up fails
virtio_user_pmd_probe(): virtio_user_dev_init fails
vdev_probe(): failed to initialize net_virtio_user3 device
vhost_user_setup(): connect error, Connection refused
virtio_user_dev_init(): backend set up fails
virtio_user_pmd_probe(): virtio_user_dev_init fails
vdev_probe(): failed to initialize net_virtio_user4 device
EAL: Bus (vdev) probe failed.
testpmd: No probed ethernet devices


DPDK ver: 18.11.3
OVS ver: 2.11.1
Host OS: debian (although this is not a actual host(bare metal), this is a
vm really)

Any advise is appreciated.
Thanks!
