Hi there,

I'm working on implementing POC based on Havana bits. Main goal for now is to get GRE to work :) Please find below details of the installation environment and issues we are facing. Any advise and support will be highly appreciated.

Thanks,

INSTALLATION ENVIRONMENT: - Two physical machines running CentOS 6.5 based install of Linux (2.6.32-431.el6.x86_64) - Each Server has 2 network interfaces each configured with static IP addresses. For this installation eth2 will be "management traffic" and eth3 will be "Data traffic". The following IP addresses are used: -- control + Neutron (combined) host eth2 172.16.1.71, eth3 172.16.10.71 -- compute host eth2 172.16.1.72, eth3 172.16.1.72 - Iptables is disabled. Also we have set selinux to permissive.

Basically we followed the steps on the wiki page to get things deployed and OVS configured. http://wiki.stackinsider.org/index.ph...

From Horizon interface, we configured Tenant Network and Started a VM. But unfortunately it is failing to get an IP from DHCP.

Checked the networking and OVS configuration, it looked good to me. Please find below the details

Core idea of setup you are interested in had been provided by http://kashyapc.com/2013/11/
However, there is some distance from POC to production running,if you
would like you may go through stuff described in my answer. It would
give you a snapshot of 3 months development in step by step details.
I am very sorry, but having ready for production , stable running
"Two Nodes F20 Clusters Neutron&GRE with only one Ehernet adapter for each node"
go back to CentOS 6.5 doesn't seem to me as a good idea. I sincerely apologize
for first redaction of my feedback

 I can provide a link based on updated  setup for Two  Fedora 20 VMs running on non-default libvirt subnet   suggested by  Kashyap Chamarthy in November 2013. Setup down here is for Two  Node Fedora 20 physical boxes with  native Havana packages installed.  I have in meantime several  Two Node Clusters been built as descibed bellow running on daily basis in QA environment for about 2.5  months. So, I am quite sure that provided HowTo is correct. Have to mention that there is no any answer file, every setup has been done manually following ,in general, original Kashyap's instructions, however setup supposed to run in meantime has several important changes ignoring those would cause all procedure to crash due to changes in Fedora 20 happened since 11/2013. All F20 updates have happened sinse 01/23 where applied to each one of working clusters.

"Setting up Two Physical-Node OpenStack RDO Havana + Neutron GRE + Gluster backend for Cinder" on Fedora 20 boxes with both Controller and Compute nodes each one having one Ethernet adapter .

Feel free to view any changes been done to configuration since 01/23 up to the most recent Link to Lxer's newswire.
So, implementing POC based on Havana bits had been, actually, done by Kashyap in November 2013.
