端口6634是ovs-vswitchd监听端口是被动连接管理的端口 所谓的被动连接端口是指，控制器可以主动连接此端口，控制此ovs，下面就是设置被动端口的 方式 ovs-vsctl set-controller s1 ptcp:8888 特别说明：相对应被动端口，主动端口（ovs主动连接并和控制器通信的端口）设置方式如下: ovs-vsctl set-controller s1 tcp:127.0.0.1:8887 主动连接本地控制器127.0.0.1:8887端口 主动连接也可以设置多个，设置方法如下 通过通信数据包得知，该ovs会和本地控制器6636和6637通信，如果有packet in事件时候会将该事件分别发一份给这两个控制器，至于两个控制器间的关系协作暂无研究。 ovs-vsctl set-controller s1 tcp:127.0.0.1:6636 tcp:127.0.0.1:6637
