Open Stack

Hi,

Based on the documentation found at
http://docs.openstack.org/folsom/openstack-compute/install/yum/content/compute-configuring-guest-network.html

I have the following network configuration where em1 is my interface to the
internet and em2 is the nic that connects to network that I want to create
virtual machines on but a couple of things are concerning me

1. br100 has a state UNKNOWN.  I believe it should have a state of UP, is
this correct ?

# ip a | grep state
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen
1000
3: em2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen
1000
4: br100: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UNKNOWN
5: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UNKNOWN
6: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 500

2. I am seeing entries in /var/log/messages that seem to indicate the
bridge is being disabled

Jul 31 14:55:56 prancer kernel: br100: port 1(em2) entering forwarding state
Jul 31 14:57:35 prancer kernel: br100: port 1(em2) entering disabled state

Can anyone spot what I have done wrong ?

All nova services appear to be running with the config as it is
