我在运行Ubuntu 12.04的PC上安装了openvswitch。我的电脑上也运行了虚拟机，其上运行着3个虚拟机（Ubuntu 12.04）。 被命名
vm-1 vm-2 vm-3 我已经在主机上configuration了openvswitch，如下所示。
sudo ovs-vsctl show #Create the virtual switch on the host machine sudo ovs-vsctl add-br lan0 #Next we create tap devices on the host machine so we can bind them to the guests VM's later. for tap in `seq 1 5`; do sudo ip tuntap add mode tap lan0-p$tap done; #check if the interfaces are there ip tuntap list #Bring up the tap interfaces. for tap in `seq 1 5`; do sudo ip link set lan0-p$tap up done; # check if the interface are up ip link #Now we use ovs-vsctl to "bind" the tap devices to "lan0" switch for tap in `seq 1 5`; do sudo ovs-vsctl add-port lan0 lan0-p$tap done; #see that the tap devices are mapped to ports in lan0 sudo ovs-vsctl list-ports lan0
在主机上执行此操作后，ifconfig的输出如下所示。

现在在“桥接适配器”中configuration的每个虚拟机上使用networking设置
vm-1 is attached to lan0-p1 vm-2 is attached to lan0-p2 vm-3 is attached to lan0-p3
我已经安装了我的主机电脑上运行的痘控制器。 我运行pox控制器来连接到我的主机如下。
./pox.py log.level –DEBUG forwarding.l2_learning
我得到的输出如下

我期望输出如下

或者类似的地方显示它正在学习不同的MAC地址。 我似乎没有得到那个。 难道我做错了什么？
我想你丢失了POX的绑定地址和端口。 您可以尝试使用以下命令：
./pox.py log.level --DEBUG forwarding.l2_learning --address=**your_address** --port=6633
