Open Stack

Hello,

I dont have the whole picture of your network architecture, but if it is
correct you should have a tap interface in br-int for your instance.
Then the br-int should be connected to br-ex through a patch (something
like int-patch-ex or similar).

The you should have a physical interface in br-ex (like eth2).

You can also try to see if the DHCP agent succesfully created ports in
your provider network (openstack port list, if you see some down ports,
then you have an issue).

Good luck!
