I am new to POX controller.The setup I have on my PC is explained below.
I have installed openvswitch on my PC with runs Ubuntu 12.04.I also have
virtual box running on my PC with 3 virtual machines (Ubuntu 12.04) running
on them.They are named
vm-1
vm-2
vm-3
I have configured the openvswitch on the Host as follows.
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
The output of ifconfig after this operation on the host is as follows.

Now using Network Settings on each virtual machines in Configured in
'Bridged Adapter' where
vm-1 is attached to lan0-p1
vm-2 is attached to lan0-p2
vm-3 is attached to lan0-p3
I have installed pox controller running on my HOST pc.I run pox controller
to connect to my host PC as follows.
./pox.py log.level --DEBUG forwarding.l2_learning
The output that I get is as follows

It shows listening on 0.0.0.0:6633 ? What is 0.0.0.0 ?
I would expect output as follows

or something similar where it shows that it is learning the different
MAC addresses.I don't seem to be getting that.Am I doing something
wrong?
Please advice,
