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.
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 targets (server) 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

Nov 01 14:45:06 juno1.localdomain systemd[1]: Started Restore LIO kernel target configuration.
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 ).
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)
juno2.localdomain - Compute (192.168.1.137)

Setup Gluster Backend for cinder in Juno
*************************************************************************
Updates /etc/cinder/cinder.conf to activate Gluster 3.5.2 backend
*************************************************************************
Gluster 3.5.2 cluster installed per http://bderzhavets.blogspot.com/2014/08/setup-gluster-352-on-two-node.html
Just one more notice ( view http://blog.nixpanic.net/2014_07_01_archive.html )
The following configuration changes are necessary for 'qemu' and 'samba
vfs plugin' integration with libgfapi to work seamlessly:
1. gluster volume set cinder-volumes57 server.allow-insecure on
2. Restarting is requiredgluster volume stop cinder-volumes57
gluster volume start cinder-volumes57
3. Edit /etc/glusterfs/glusterd.vol to have a line :
option rpc-auth-allow-insecure on
4. Restart glusterd is required :
service glusterd restart
Nova.conf (on Compute Node) should have entry :-
qemu_allowed_storage_drivers = gluster
enabled_backends=gluster,lvm52
[gluster]
volume_driver = cinder.volume.drivers.glusterfs.GlusterfsDriver
glusterfs_shares_config = /etc/cinder/shares.conf
glusterfs_mount_point_base = /var/lib/cinder/volumes
volume_backend_name=GLUSTER
[lvm52]
iscsi_helper=lioadm
volume_group=cinder-volumes52
volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver
iscsi_ip_address=192.168.1.127
volume_backend_name=LVM_iSCSI52
