I want to test dpdk vhost-user port on ovs to follow https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ov s-today-using-dpdk-200;
I create ovs+dpdk environment followed INSTALL.DPDK.md; and create 2 VM2, try to ping each other but show me "Destination Host Unreachable"; Dump-flows shows packets matched the flow, but can't output to port 4, why ? I can't get any useful error or warning info from ovs-vswitchd.log. ovs-ofctl dump-flows ovsbr0 NXST_FLOW reply (xid=0x4): cookie=0x0, duration=836.946s, table=0, n_packets=628, n_bytes=26376, idle_age=0, in_port=3 actions=output:4 cookie=0x0, duration=831.458s, table=0, n_packets=36, n_bytes=1512, idle_age=770, in_port=4 actions=output:3 root@host152:/usr/local/var/run/openvswitch# ovs-vsctl show 03ae6f7d-3b71-45e3-beb0-09fa11292eaa Bridge "ovsbr0" Port "vhost-user-1" Interface "vhost-user-1" type: dpdkvhostuser Port "ovsbr0" Interface "ovsbr0" type: internal Port "dpdk1" Interface "dpdk1" type: dpdk Port "vhost-user-0" Interface "vhost-user-0" type: dpdkvhostuser Port "dpdk0" Interface "dpdk0" type: dpdk Start VM info: qemu-system-x86_64 -m 1024 -smp 2 -hda /root/vm11.qcow2 -boot c -enable-kvm -vnc 0.0.0.0:1 -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=00:00:00:00:01:12,netdev=mynet1 -object memory-backend-file,id=mem,size=1024M,mem-path=/dev/hugepages,share=on -numa node,memdev=mem -mem-prealloc -d exec qemu-system-x86_64: -netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce: chardev "char1" went up
