RDO Liberty Set up for three Nodes (Controller+Network+Compute) ML2&OVS&VXLAN on CentOS 7.1

As advertised officially

In addition to the comprehensive OpenStack services, libraries and clients, this release also provides Packstack, a simple installer for proof-of-concept installations, as small as a single all-in-one box and RDO Manager an OpenStack deployment and management tool for production environments based on the OpenStack TripleO project

In posting bellow I intend to test packstack on Liberty to perform classic three node deployment.  If packstack will succeed then post installation  actions  like VRRP or DVR setups might be committed as well. One of the real problems for packstack is HA Controller(s) setup. Here RDO Manager is supposed to get a significant advantage, replacing with comprehensive CLI a lot of manual configuration.

Following bellow is brief instruction  for three node deployment test Controller&&Network&&Compute for RDO Liberty, which was performed on Fedora 22 host with KVM/Libvirt Hypervisor (16 GB RAM, Intel Core i7-4790  Haswell CPU, ASUS Z97-P ) Three VMs (4 GB RAM,4 VCPUS)  have been setup. Controller VM one (management subnet) VNIC, Network Node VM three VNICS (management,vtep’s external subnets), Compute Node VM two VNICS (management,vtep’s subnets)

SELINUX stays in enforcing mode.

I avoid using default libvirt subnet 192.168.122.0/24 for any purposes related with VM serves as RDO Liberty Nodes, by some reason it causes network congestion when forwarding packets to Internet and vice versa.

*********************************************************************************
1. First Libvirt subnet “openstackvms”  serves as management network.
All 3 VM are attached to this subnet
**********************************************************************************
2. Second Libvirt subnet “public” serves for simulation external network  Network Node attached to public,latter on “eth2” interface (belongs to “public”) is supposed to be converted into OVS port of br-ex on Network Node. This Libvirt subnet via bridge virbr2 172.24.4.225 provides VMs running on Compute Node access to Internet due to match to external network created by packstack installation 172.24.4.224/28.
***********************************************************************************
3.Third Libvirt subnet “vteps” serves  for VTEPs endpoint simulation. Network and Compute Node VMs are attached to this subnet. ***********************************************************************************

Next step to performed on Network Node :-
*************************************************

# chkconfig network on
# systemctl stop NetworkManager
# systemctl disable NetworkManager
# service network restart

OVS PORT should be eth2 (third Ethernet interface on Network Node)
  Libvirt bridge VIRBR2 in real deployment is a your router to External
  network. OVS BRIDGE br-ex should have IP belongs to External network
