acs 4.3.1 cannot find bridge under KVM advanced zone setup

[Sebastien Goasguen <ru...@gmail.com>]

hi folks,

I am doing a 4.3.1KVM install on one centOS 6.6 host (mgt + agent).

Trying to setup an advanced zone with two bridges

I have two bridges br0 and br1 which have IPs like so:

br0       Link encap:Ethernet  HWaddr 00:00:00:00:00:00  
          inet addr:172.16.0.1  Bcast:172.16.0.255  Mask:255.255.255.0

br1       Link encap:Ethernet  HWaddr 2E:2B:6E:E6:83:35  
          inet addr:172.18.0.1  Bcast:172.18.0.255  Mask:255.255.255.0

br0 used for public and mgmt and br1 for guests.

During the host install, I get this error:

2014-11-10 12:25:53,821 DEBUG [c.c.a.m.AgentManagerImpl] (AgentConnectTaskPool-209:ctx-687f8403) Failed to handle host connection: com.cloud.exception.ConnectionException: Incorrect Network setup on agent, Reinitialize agent after network names are setup, details : Can not find network: br1

the agent log just shows:

If I don't specify traffic labels everything more of less works, but with traffic labels if fails with this. 

Anybody will have a clue why cloudstack would not be able to recognize the bridges ?
