public-interface ignored

hi,

running openstack essex with vlan-networking:
--network_manager=nova.network.manager.VlanManager
--vlan_interface=bond0
--public_interface=bridge_130
--auto_assign_floating_ip=True

all works great except for floating ips. the problem is, that the
floating ips are assigned to eth0 instead of bridge_130. I can't get a
clue out of the logs:

2012-07-24 11:24:02 DEBUG nova.service [-] public_interface : bridge_130
from (pid=31192) wait /usr/lib/python2.7/dist-packages/nova/service.py:411

=> so during startup it realizes that bridge_130 is the
public-interface. great. But then the floating ip is assigned:

2012-07-24 11:24:26 DEBUG nova.utils [-] Running cmd (subprocess): sudo
nova-rootwrap ip addr add xx.xx.xx.129/32 dev eth0 from (pid=31192)
execute /usr/lib/python2.7/dist-packages/nova/utils.py:219

this process finishes without errors, the problem is that eth0 is just
not my public network interface. What's wrong? is there something in the
database that I should change?

Looking through the code, in the
nova.network.manager.FloatingIP.associate_floating_ip() call, I see this:

interface = FLAGS.public_interface or floating_ip['interface']

on line 511 (in current HEAD of branch).

The only thing I could think of is that you created your floating IPs
before setting your FLAGS.public_interface?

Best,
-jay
