Storage Node (LVMiSCSI) deployment for RDO Liberty on CentOS 7.2

  Posting bellow via straightforward  RDO Liberty deployment demonstrates
that Storage Node might work as traditional iSCSI Target Server and each
Compute Node is actually iSCSI initiator client. This functionality is provided
by tuning Cinder && Glance Services running on Storage Node. It's also
important to understand that Storage node should be brought up after Controller
to be able connect it's services to AMQP broker running on Controller (rabbitmq-server).

  Following bellow is brief instruction for 4 node deployment test Controller & Network & Compute & Storage  on RDO Liberty (CentOS 7.1), which was performed on Fedora 21 host with KVM/Libvirt Hypervisor  (32 GB RAM, Intel Core i7-4790  Haswell CPU, ASUS Z97-P ) .Four 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), Storage Node VM one VNIC (management)
Setup :-

192.169.142.127 - Controller Node
192.169.142.147 - Network Nodes
192.169.142.137 - Compute Node
192.169.142.157 - Storage Node (LVMiSCSI)

1. First Libvirt subnet "openstackvms"  serves as management network.
All 4 VM are attached to this subnet
*********************************************************************************************************
2. Second Libvirt subnet "external" serves for simulation external network 
Network Nodes attached to "external",latter on "eth2" interfaces (belongs to "external") which are supposed to be converted into OVS ports of br-ex(s) on Network Nodes. This Libvirt subnet via bridge virbr2 172.24.4.25 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 Nodes are attached to this subnet.
