Thanks all for your help. I managed to get things working, kind of.
What did the trick was a combination of two things:
1) making sure the brige_mappings, bridge_uplinks and public subnet
settings were correct
2) removing br-ex from /etc/network/interfaces and letting openvswitch
create the br-ex bridge
Traffic flows between instances and the outside world are fine now even
though openvswicht (and thus neutron and the horizon dashboard) are still
reporting qg-* ports on br-ex and qr-* ports on br-int to be down. Does
anybody know why that is?
Cheers,
Tom
