Post bellow follows up http://cloudssky.com/en/blog/RDO-OpenStack-Juno-ML2-VXLAN-2-Node-Deployment-On-CentOS-7-With-Packstack/ however answer file provided here allows in single run create Controller && Compute Node.Based oh RDO Juno release as of 10/27/2014 it doesn’t require creating OVS bridge br-ex and OVS port enp2s0 on Compute Node. It also doesn’t install nova-compute service on Controller. Gluster 3.5.2 setup also is performed in way which differs from similar procedure on IceHouse && Havana RDO releases. Two boxes have been setup , each one having 2 NICs (enp2s0,enp5s1) for Controller && Compute Nodes setup. Before running`packstack –answer-file=TwoNodeVXLAN.txt` SELINUX set to permissive on both nodes.Both enp5s1’s assigned IPs and set support VXLAN tunnel (192.168.0.127, 192.168.0.137 ). Services firewalld and NetworkManager disabled, IPv4 firewall with iptables and service network are enabled and running. Packstack is bind to public IP of interface enp2s0 192.169.1.127, Compute Node is 192.169.1.137 ( view answer-file ).
I have also to note that in regards of LVMiSCSI cinder backend support on CentOS 7 post http://theurbanpenguin.com/wp/?p=3403 is misleading. Name of service making changes done in targetcli persistent between reboots is “target” not “targetd”
To setup iSCSI initiator on CentOS 7 ( activate LIO kernel support) you have
to issue :-
# systemctl enable target
# systemctl start target
# systemctl status target -l
target.service – Restore LIO kernel target configuration

Setup configuration
– Controller node: Nova, Keystone, Cinder, Glance, Neutron (using Open vSwitch plugin && VXLAN )
– Compute node: Nova (nova-compute), Neutron (openvswitch-agent)
juno1.localdomain – Controller (192.168.1.127)
