Amir, I haven't tried such a configuration so far - but I don't think it will work.
So your goal is to get it running with a single NIC. So what should work is the following setup: Use br-ex as external bridge and plug your eth interface into it (Note this will break IP connection, so better you log in via a separate interface/mgmt console!! Otherwise you might be locked out!). Then configure the ip that was on your eth interface on your br-ex (you will get back ip connectivity via this ip). With this setup - your tenant networks uses tunneling, while the ip used for it is the br-ex IP - your public network will be a flat network Alternative, if you want a public vlan network: - create a vlan device on top of your eth interface - plug vlan device into br-ex -> external network will do vlan and your tunnels will use your interface ip If you want a vxlan external network, you could do it similar like with vlan, but using a vxlan device instead. I haven't tried configuring the openvswitch external bridge for vxlan via Openstack so far.
