Packstack installation failed as neutron does not start

Hello Openstackers,

This is my maiden attempt to perform an Openstack Installation. I have googled and researched through Openstack neutron failures but none of the solutions have worked for me. As a last resort I place my faith in this network. Please help me resolve my issue.

Thanks in advance for your guidance and support.

========Overview========

Architecture

Physical Server - I Hypervisor - OVS 3.3.2

VM1- Oracle Linux 6 Update 6 - Openstack Controller [172.30.21.160]

VM2- Oracle Linux 6 Update 6 - Openstack Neutron [172.30.21.161]

Physical Server - II Hypervisor - OVS 3.3.2

VM1- Oracle Linux 6 Update 6 - Openstack Compute Node [172.30.21.160]

VM2- Oracle Linux 6 Update 6 - Openstack Compute Node [172.30.21.161]

I am using Packstack to install Openstack and I use the config file generator to do the same -

Hi, Once you end up with neutron error.Ensure the rabbitmq is active and running and Static IP is associated to eth interface rather than a bridge.Restart rabbitmq server and try running packstack answer file.

@Praveen N - Thank you for your reply. I did check for RabbitMQ server and that seems to be running and upon restarting and trying Packstack installation failed again. :(

I would also recommend you create third VM3 for compute node, rather then use Controller && Network Nodes as Compute Nodes. You may have a look at
http://bderzhavets.blogspot.com/2014/...
One more notice I am not sure Oracle Linux 6.6 as clone of RHEL 6.6 would work with Juno.
Anyway as OS installed on VMs it would better to be replaced by CentOS 7, which is well tested with Juno packstack installs many times.
You also posted tag "devstack-neutron" . What you mean by that ?

Thank you dbaxps. I am unable to get this architecture running. I am using the following - VM 1 - Controller 172.30.21.160 : x.x.20.160 VM 2 - Neutron 172.30.21.161 : x.x.20.161 VM 3 - Compute 1 172.30.21.162 : x.x.20.162 VM 4 - Compute 2 172.30.21.163 : x.x.20.163 Each VM has 2 interfaces

I have not been able to get packstack to do multi-node installation. It works fine when I install Nova-Network Model where Control & Network are in the same server but when I separate them it does not seem to work. I have installed the nodes separately following the Openstack Config Guide for RHEL.
