gdb了ovs的代码，发现是 dpdk的imiss计数在不断的丢包。
看了ovs-openvswitchd的日志，重启时发现如下行：
3590 2018-05-21T11:57:03.427Z|00033|timeval|WARN|Unreasonably long 22418ms poll interval (474ms user, 21612ms system) 3591 2018-05-21T11:57:03.427Z|00034|timeval|WARN|faults: 141393 minor, 0 major 3592 2018-05-21T11:57:03.427Z|00035|timeval|WARN|disk: 0 reads, 16 writes 3593 2018-05-21T11:57:03.427Z|00036|timeval|WARN|context switches: 14 voluntary, 120 involuntary

[root@vrouter1 ~]# ovs-appctl vlog/set file:dbg
重装新版dpdk
[root@vrouter1 ovs-dpdk]# ls dpdk-17.11.2.tar.xz dpdk-stable-17.11.2 openvswitch-2.9.1 openvswitch-2.9.1.tar.gz
1. 编译dpdk
[root@vrouter1 dpdk-stable-17.11.2]# make config T=$RTE_TARGET O=$RTE_TARGET Configuration done using x86_64-native-linuxapp-gcc [root@vrouter1 dpdk-stable-17.11.2]# cd x86_64-native-linuxapp-gcc/ [root@vrouter1 x86_64-native-linuxapp-gcc]# make
2. 编译ovs
[root@vrouter1 openvswitch-2.9.1]# ./boot.sh [root@vrouter1 openvswitch-2.9.1]# ./configure --with-dpdk=$RTE_SDK/$RTE_TARGET [root@vrouter1 openvswitch-2.9.1]# make [root@vrouter1 openvswitch-2.9.1]# make install
3. 运行
[root@vrouter1 ovs-dpdk]# cat ovs.sh export PATH=$PATH:/usr/local/share/openvswitch/scripts export DB_SOCK=/usr/local/var/run/openvswitch/db.sock ovs-ctl --no-ovs-vswitchd start #ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true #ovs-ctl --no-ovsdb-server --db-sock="$DB_SOCK" start ovs-ctl --no-ovsdb-server start [root@vrouter1 ovs-dpdk]#
4. 配置
[root@vrouter1 Datapath]# dpdk-devbind -b vfio-pci 0000:01:00.0 [root@vrouter1 ovs-dpdk]# ovs-vsctl add-br br-phy -- set bridge br-phy datapath_type=netdev [root@vrouter1 ovs-dpdk]# ovs-vsctl add-port br-phy dpdk-p0 -- set Interface dpdk-p0 type=dpdk options:dpdk-devargs=0000:01:00.0
[root@vrouter1 ovs-dpdk]# ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev [root@vrouter1 ovs-dpdk]# ovs-vsctl add-port br0 vxlan0 -- set Interface vxlan0 type=vxlan options:remote_ip=10.0.0.163 options:local_ip=10.0.0.161 options:in_key=flow options:out_key=flow
#>ovs-appctl ovs/route/add 10.0.0.163/24 br-phy [root@vrouter1 ~]# ip a add 10.0.0.161/24 dev br-phy
