Xen Virtualization on Linux and Solaris: RDO Mitaka Virtual Deployment having real physical network as External

Nova-Docker driver is installed on Compute node which is supposed to run several Java EE Servers as light weight Nova-Docker Containers (instances) having floating IPs on external flat network (actually real office network 192.168.1.0/24) . General Setup RDO Mitaka ML2&OVS&VLAN 3 Nodes.  VLAN tenant's segregation for RDO lansdcape was selected to avoid DVR configuration Controller && Compute Cluster.
Details here Setup Docker Hypervisor on Multi Node DVR Cluster RDO Mitaka

Configuration RDO Mitaka :-

Controller/Network (VM) 192.169.142.127 (eth0 -mgmt, eth1- vlan
    vm/data, eth2 external )
Compute (VM) 192.169.142.137 (eth0 -mgmt, eth1- valn, vm/data)
Storage    (VM ) 192.169.142.147 (eth0 -mgmt)

********************************************************************************************
Office LAN 192.168.1.0/24 is supposed to match external network (configured via flat network provider ) for VM's deployed system . VIRTHOST (F23) is based on linux bridge br0 having original interface enp3s0 as source interface
