Hi all,
I build a ovs-dpdk and vhost-user POC through INSTALL.DPDK.md.
My host is centos7.0
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?
