Hi,<br>
<br>
Just found this doc on RDO site, which's very similar to Damon's
setup:<br>
<a class="moz-txt-link-freetext" href="http://openstack.redhat.com/Neutron_with_existing_external_network">http://openstack.redhat.com/Neutron_with_existing_external_network</a><br>
<br>
<br>
Hope it helps.<br>
<br>
Cheers,<br>

<div>Hi Anatoly,<br>
<br>
</div>
I have installed openstack by packstack before, maybe my
installation can help you.<br>
<br>
</div>
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.<br>
<br>
</div>
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 :<br>
<br>
</div>
<div>eth0:<br>
DEVICE=eth0<br>
ONBOOT=yes<br>
HWADDR=00:E0:81:D8:43:BE<br>
TYPE=OVSPort<br>
DEVICETYPE=ovs<br>
OVS_BRIDGE=br-ex<br>
<br>
</div>
<div>br-ex:<br>
<pre class="">DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=<span class="">static</span>
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
</pre>
<pre class="">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.
</pre>
Hope this helps,<br>

As you're using RDO, you can take a look at your answer file
used during packstack installation. You can also search <a

Hello,<br>
<br>
I've installed Openstack Havana (with Neutron
networking) on single node running<br>
Scientifcic Linux 6.4 (RHEL 6.4) using packstack
--allinone.<br>
<br>
Installer have created only one bridge - br-ex:<br>
# ovs-vsctl show<br>
76aa02e5-a442-40c6-8c77-e0471d1a8256<br>
Bridge br-ex<br>
Port br-ex<br>
Interface br-ex<br>
type: internal<br>
ovs_version: "1.11.0"<br>
<br>
<br>
My single node has 2 physical NICs, eth0 & eth1.
eth0 is for connection to local<br>
(external) network and<br>
eth1 for internal (cluster) network.<br>
Before installing Openstack I created 2 linux bridges,
br0 is on eth0, br1 is on eth1<br>
to be able to launch virtual machine (with 2 network
interfaces) in KVM.<br>
<br>
Command "route" shows:<br>
<br>
Kernel IP routing table<br>
Destination Gateway Genmask Flags
Metric Ref Use Iface<br>
239.2.11.72 * 255.255.255.255 UH

1023 0 0 br-ex<br>
default 212.192.96.129 0.0.0.0 UG
0 0 0 br0<br>
<br>
Here br0 is for external network, br1 for internal
network.<br>
<br>
<br>
As far as understand one more bridge br-int should be
created. How to create it ?<br>
Bridges br-ex and br-int should be associated with
physical NICs ?<br>
But eth0 & eth1 are already are assigned to
bridges br0 & br1 respectively<br>
<br>
Can anybody help me to clarify this issue ?<br>
May be some commands ?<br>
<br>
Thanks.<br>
Anatoly.<br>
