Hi  all,


I build a ovs-dpdk and vhost-user POC through INSTALL.DPDK.md.

There is a br0 with dpdk0 and vhost-user-0
I build dpdk with 2.0.0 and ovs with branch 2.4
# ovs-vsctl show
ovs-vsctl show
c38093a7-6c7e-4d6a-a7c1-627d95acbdc6
    Bridge "br0"
        Port "br0"
            Interface "br0"
                type: internal
        Port "vhost-user-0"
            Interface "vhost-user-0"
                type: dpdkvhostuser
        Port "dpdk0"
            Interface "dpdk0"
                type: dpdk

I setup a virtual machine succesfully. qemu version is 2.3.0 which is ok for vhost-user

# qemu-system-x86_64 -smp 2 -m 1024 -hda ubuntu.img -vnc :1 -chardev socket,id=char1,path=/usr/local/var/run/openvswitch/vhost-user-0 -netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce -device virtio-net-pci,mac=22:33:44:55:66:77,netdev=mynet1 -object memory-backend-file,id=mem,size=1024M,mem-path=/dev/hugepages,share=on -numa node,memdev=mem -mem-prealloc

qemu-system-x86_64: -netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce: chardev "char1" went up

I set the br0 10.0.0.2/24 and virtual machine eth0 10.0.0.1/24
But they can't ping each other

I  can see the vhost-user-0 port always show down and there are some dropped packets which are sent from br0.

Are there some wrong with my POC?
