I can't get any useful error or warning info from ovs-vswitchd.log.
Do any statistics increment on the interface on the VM? Eg rx errors? What versions of OVS / DPDK / QEMU are you using? Some things to try if you haven't already: QEMU v2.5.0 Disable mergeable rx buffers like so: -device virtio-net-pci,mac=00:00:00:00:01:12,netdev=mynet1, mrg_rxbuf=off Thanks, Ciara > > 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 _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
