Nova and Neutron work-flow && CLI for HAProxy/Keepalived 3 Node Controller RDO Liberty

The correct name of this post is supposed to be "Nova and Neutron workflow && CLI for HAProxy/Keepalived 3 Node Controller RDO Liberty in an appropriate amount of detail". It follows up http://lxer.com/module/newswire/view/222164/index.html . All environment has been built via Nova and Neutron CLI ( no Horizon involvement ).
Neutron work-flow on Controller is described including OVS flow rules on external bridge created by flat external network provider , eth0 external interface as VLAN OVS port of bridge br-eth0 and br-int

First create keystonerc_admin to provide admin ability manage via CLI

When "external_network_bridge = " , Neutron places the external 
interface of the router into the OVS bridge specified by the 
"provider_network" provider attribute in the Neutron network. Traffic is
processed by Open vSwitch flow rules. In this configuration it is 
possible to utilize flat and VLAN provider networks.

The packet exits the qg-a37e106e-70 (which is outgoing interface of 
corresponding qrouter-namespace attached to br-int due to external network provider involvment)
interface, where it is assigned the VLAN tag associated with the external network 3.
The packet is delivered to the external bridge, where a flow rule strip the VLAN tag 3.
The packet is sent out the physical interface associated with the bridge.

Assuming eth0 is your interface attached to the external network, create two files in /etc/sysconfig/network-scripts/ as follows (change MTU if you need):

cat <<EOF > /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE=eth0

DEVICETYPE=ovs 
TYPE=OVSPort 
OVS_BRIDGE=br-eth0

OVSBOOTPROTO=none 
TYPE=OVSBridge 
ONBOOT=yes BOOTPROTO=static 
MTU="9000" 
NM_CONTROLLED=no 
EOF

Restart the network for the changes to take effect
