VRRP four nodes setup on RDO Liberty (CentOS 7.1)

UPDATE 10/28/2015

    I clearly understand that following advanced RH's technology as RDO Manager, I am supposed to set up 1 VM for undercloud, 3 VMs for HA overcloud Controller and 2 VMs for overcloud Compute Nodes. So, 6 VMs should be installed on desktop  box. One person wrote (on RDO Mailing list) that the only problem is 32 GB of RAM and he is ready to go with i7 4770 Haswell CPU. Doing sample bellow (just 4 VMs) on 32 GB desktop with i7 4790 I was experiencing performance issues not due to memory swap, but due to 4 Core limitation for any i7 Haswell CPU. I am forced to run packstack for POC tasks due to insufficient power of desktop Haswell CPUs. Actually, CPU like Intel® Xeon® Processor E5-2690 (8 Cores,16 threads) would  allow to test virtual configs of RDO Manager.

END UPDATE

   Sample bellow demonstrates uninterrupted access, providing via HA Neutron router,  to cloud VMs  running on Compute node, when two installed Network Nodes node are swapping MASTER and BACKUP roles (as members of keepalived pair).

Due to Lxer's  moderators posted (sic) before  "uninterrupted access", I have to notice that some downtime obviously always occurs ( several minutes ) required for BACKUP box comes to MASTER state.

    Following bellow is brief instruction for 4 node deployment test Controller & 2xNetwork & Compute 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, 2xNetwork Nodes VM three VNICS (management,vtep's external subnets),  Compute Node VM two VNICS (management,vtep's subnets)

Setup :-

192.169.142.127 - Controller Node
192.169.142.147,192.169.142.157 - Network Nodes
192.169.142.137 - Compute Node

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.

Verify VRRP advertisements from the master node HA interface IP address on corresponding network interface:


   Verification status of neutron services  on each one of Network Nodes
    


    Running VMs
   
 
   Connectivity verification


   Current MASTER is 192.169.142.157

 
   MASTER 192.169.142.157 stopped , 192.169.142.147 changing state from
   BACKUP to MASTER   

 
    Connectivity verification to 172.24.4.231

 
  192.169.142.157 brought up again

  

   192.169.142.157 goes to MASTER State again due to 192.169.142.147 shutdown.
