            Bug ID: 1036
           Summary: vhost primary and secondary process symmetric test
                    meet issue
           Product: DPDK
           Version: 22.03
          Hardware: x86

            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

  Target Milestone: ---

Prerequisites
-------------
1. Compile symmetric_mp example application::
meson configure -Dexamples=3Dmulti_process/symmetric_mp
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc

Steps
-----
1. Launch vhost testpmd as primary process::

./x86_64-native-linuxapp-gcc/examples/dpdk-symmetric_mp -l 1 -n 4 \
--vdev 'net_vhost,iface=3Dvhost-net,queues=3D2,client=3D1' \
--vdev 'net_vhost1,iface=3Dvhost-net1,queues=3D2,client=3D1' \
--proc-type=3Dauto -- -p 3 --num-procs=3D2 --proc-id=3D0

2. Launch vhost testpmd as secondary process::=20=20

./x86_64-native-linuxapp-gcc/examples/dpdk-symmetric_mp -l 2 -n 4 \
--vdev 'net_vhost,iface=3Dvhost-net,queues=3D2,client=3D1' \
--vdev 'net_vhost1,iface=3Dvhost-net1,queues=3D2,client=3D1' \
--proc-type=3Dauto -- -p 3 --num-procs=3D2 --proc-id=3D1

3. Launch virtio-user::
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -n 4 -l 7-8 --no-pci
--file-prefix=3Dvirtio1 \
--vdev=3Dnet_virtio_user1,mac=3D00:01:02:03:04:05,path=3D./vhost-net,queues=
=3D2,server=3D1,mrg_rxbuf=3D0,in_order=3D0
\
-- -i --nb-cores=3D1 --rxq=3D2 --txq=3D2 --txd=3D1024 --rxd=3D1024

when launch virtio-user:
VHOST_CONFIG: (0) device not found.
