Hi,
Just found this doc on RDO site, which's very similar to Damon's setup:
http://openstack.redhat.com/Neutron_with_existing_external_network
Hope it helps.
Cheers,

Hi Anatoly,
I have installed openstack by packstack before, maybe my installation
can help you.
First, you don't need to create Linux bridge before you use packstack.
PackStack enable Neutron by default, so you should configure
OpenVSwitch bridge instead of Linux bridge.
Second, as you use eth0 to connect to external network, you should
make the br-ex's same to eth0's IP, and make eth0 as a port of br-ex,
these all configure by ifcfg. For example, here is my network
configure of my vm which run packstack :
eth0:
DEVICE=eth0
ONBOOT=yes
HWADDR=00:E0:81:D8:43:BE
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex
br-ex:
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=10.1.199.8 # Note, this is your IP of eth0 before, to connect to
external network!
NETMASK=255.255.255.0
ONBOOT=yes
Third, the eth1 doesn't matter as packstack enabled ip namespace if you use
all-in-one in mp opinion.
You can use "ip netns" to make sure you have enabled ip namespace.
Hope this helps,
Damon

Hi,
As you're using RDO, you can take a look at your answer file used
during packstack installation. You can also search
http://openstack.redhat.com/forum/ see if there are relevant
questions/answers.
Cheers,

Hello,
I've installed Openstack Havana (with Neutron networking) on
single node running
Scientifcic Linux 6.4 (RHEL 6.4) using packstack --allinone.
Installer have created only one bridge - br-ex:
# ovs-vsctl show
76aa02e5-a442-40c6-8c77-e0471d1a8256
Bridge br-ex
Port br-ex
Interface br-ex
type: internal
ovs_version: "1.11.0"
My single node has 2 physical NICs, eth0 & eth1. eth0 is for
connection to local
(external) network and
eth1 for internal (cluster) network.
Before installing Openstack I created 2 linux bridges, br0 is
on eth0, br1 is on eth1
to be able to launch virtual machine (with 2 network
interfaces) in KVM.
Command "route" shows:
Kernel IP routing table
Destination Gateway Genmask Flags Metric
Ref Use Iface
239.2.11.72 * 255.255.255.255 UH 0 0
0 br1
172.24.4.224 * 255.255.255.240 U 0 0
0 br-ex
212.192.96.128 * 255.255.255.224 U 0 0
0 br0
192.168.1.0 * 255.255.255.0 U 0 0
0 br1
link-local * 255.255.0.0 U 1007 0
0 br0
link-local * 255.255.0.0 U 1008 0
0 br1
link-local * 255.255.0.0 U 1023 0
0 br-ex
default 212.192.96.129 0.0.0.0 UG 0 0
0 br0
Here br0 is for external network, br1 for internal network.
As far as understand one more bridge br-int should be created.
How to create it ?
Bridges br-ex and br-int should be associated with physical NICs ?
But eth0 & eth1 are already are assigned to bridges br0 & br1
respectively
Can anybody help me to clarify this issue ?
May be some commands ?
Thanks.
Anatoly.
