Hi George,
in the guide you are using nova-network service is deployed on the
compute node, so you need br100 only on it (and every compute node)
so forget what i wrote about controller and compute
as a guide to setup br100 try this link
(http://docs.openstack.org/grizzly/openstack-compute/install/yum/content/compute-configuring-guest-network.html)
but be careful with the interface you use, in your case (as described in
the guide you follow) eth1 is the right one
for the deployment i would suggest you try using a deployment tool like
RDO, following the guide found under the link below
http://openstack.redhat.com/Quickstart
then there are configuration option on setting all-in-one or multi-node
deployments
as well as using neutron or nova-network or adding compute nodes
for the networking part i suggest try using neutron, but this might not
be an easy solution as you will need to study and understand some things
about it.
in any case, keep updating and i will help

Hello again!
No the br100 was not created automatically unfortunately! There is
also this bug report:
https://bugs.launchpad.net/openstack-manuals/+bug/1241331
Since it wasn't created automatically I am asking if it has to be on
both nodes (controller + compute) in order for the network to work
correctly? Furthermore, I would like to know how should it be bridged
in order to achieve floating (public) IPs?
If it's easier for you or there is a guide that you can point me to I
would be happy to try with neutron instead of nova-network.
Best,
G.

Hi George,
Personally i have not dealt with this setup, but i can follow and
assist you further.
According to the related bug report
(https://bugs.launchpad.net/ubuntu/+bug/1243588)
"br100 is automatically set up by nova-network, you do not need to
manually create it"
is that the case on your setup?
Best,

Dear Thanassi,
thank you very much for your interest! First of all let me inform
you that you are right and I am going with the first (a) approach
(nova-network).
The guide I was following and the place on which the specific
problem arises is this one:
http://docs.openstack.org/havana/install-guide/install/yum/content/nova-network.html
As you can see by yourself many people on the comment session below
are trying to understand how to move on with the br100 interface.
In my case the interface wasn't created automatically (although in a
previous bug that I 've found the say that this was fixed but
apparently it hasn't been in my case). So I 've tried to move on and
created the br100 on the compute node without success. If I
understand correctly, according to your suggestion the br100 has to
exist on the controller node as well. Am I right? Should I create
the br100 on both nodes?? Do you have any further suggestions on how
to assign floating (public) IPs to the VMs? Currently I am having
two nodes (controller + compute) with two NIC interfaces each! One
of them is used in order to connect directly each to node to the
other, while the other is used to connect to the public LAN with a
static IP. Any help and configuration schema much appreciated!
All the best,
G.

Hi George,
It would be a pleasure to help you on this, do you still have
problems with the deployment?
In OpenStack there are two types of networking that can be used
a)nova-network and b)neutron.
Given your specified question i assume you are going with option a),
then in that case the br100 bridge should be present (manually created
- if you follow a manual deployment) on the controller node.
May be you can provide the link of the guide you are following so
that we check if there is a need for correction on this.
One more thing, since you are using Centos you can consider using
RedHat RDO ( http://openstack.redhat.com ) for the deployment.
Feel free to contact me with regard to any issues you have.
Best regards,
Thanassis

Hi people!
I am following the exact steps of the "Openstack Installation
Guide" for Havana on a CentOS 6.5
The problem is that when I try create the network on the
controller node using this :
nova --debug network-create vmnet --fixed-range-v4=x.x.x.x/32
--bridge-interface=br100 --multi-host=T
I get an error that the br100 interface cannot be found.
So, my question is the following: should this interface appear on
the controller node , on the compute node or on both nodes?
What do I have to do to set it up properly since it doesn't appear
on any of them??
I have found this bug for CentOS 6.4 and I am not sure that has
been corrected for 6.5.
Could someone help me a bit with this??
Best,
G.
