Public bug reported:

Hello,
I am running newton openstack in ubuntu 16.04 platform. I have one controller node and one compute node. I created network in provider network as shown in http://docs.openstack.org/newton/install-guide-ubuntu/launch-instance-provider.html

Howerver, I didnt see any provider bridge in my controller. 
My ifconfig says: there is only one tap interface. I have one netns (qdhcp-d6aee39b-8a97-4a69-98c7-9d94093f54af)

I ping from qdhcp namespace with the following command:

sudo ip netns exec qdhcp-d6aee39b-8a97-4a69-98c7-9d94093f54af ping 203.0.113.111
That is IP address of VM. 

The message " Destination Host Unreachable" is shown.

I tried to debug it. I found provider bridge is not created in
controller node. tcpdump shows ARP requests. But provider interface does
not show anything.

In contrast, compute node has provider bridge. I am using  Linux bridge
agent in controller and compute. Both are running.
