Hi Yngyi, 

this absolutely makes sense. 

As soon as you add a port to a bridge (doesn't matter if linux- or
ovs-bridge) it cannot be used as ip interface anymore. What you have to
do after you've added this interface to br-ex, you have to "move up" the
ip address to the br-ex. 

e.g. 
> ifconfig em3 0
> ifconfig br-ex 172.22.17.12/24

And you should be fine


Hope this helps!
