The procedure below has been used to create a 3-node OPNFV install using Intel NUC i7 nodes with 16GB RAM, 250MB SSD, and 1 TB HDD. The install uses one NUC for the Jumphost, and one each for the controller (OpenStack + ODL) and the compute nodes.

==== Jumphost Installation and OPNFV Deployment ====

  * Includes instructions from http://artifacts.opnfv.org/genesis/foreman/docs/installation-instructions.html
  *  install Centos 7 x86_64 minimal server: CentOS-7-x86_64-Minimal-1503-01.iso 
  *  during install, add user opnfv
  *  once active, login to opnfv account from console 
<code>
ip addr
</code>

  *  note IP address of enp0s25 - will set it in ifcfg-enp0s25 per the notes below

  *  add opnfv account to sudoers after "root    ALL=(ALL)       ALL"
<code>
su
visudo
opnfv   ALL=(ALL)       ALL
</code>

  *  update
<code>
sudo yum -y update
</code>

  *  reboot and select updated kernel so correct kernel headers can be obtained in virtualbox setup
<code>
sudo shutdown -r 0
</code>

  *  Select boot option: CentOS Linux (3.10.0-229.14.1.e17.x86_64) 7 (Core)

  *  configure hostname
<code>
sudo vi /etc/hostname
jumphost1.opnfv.org
</code>

  *  Disable NetworkManager
<code>
sudo systemctl stop NetworkManager
sudo systemctl disable NetworkManager
</code>

  *  configure single NIC as static per IP assigned during install
<code>
sudo vi /etc/sysconfig/network-scripts/ifcfg-enp0s25
TYPE="Ethernet"
BOOTPROTO="static"
IPADDR=192.168.1.201
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
NM_CONTROLLED="no"
(rest as-is)
</code>

  *  Restart networking
<code>
sudo service network restart
sudo setenforce 0
</code>

  *  Edit /etc/resolv.conf and add a nameserver
<code>
sudo vi /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
</code>

  *  Disable selinux:
<code>
sudo setenforce 0
sudo sed -i 's/SELINUX=.*/SELINUX=permissive/' /etc/selinux/config
</code>

  *  Disable firewalld:
<code>
sudo systemctl stop firewalld
sudo systemctl disable firewalld
</code>

  *  install and start ntp
<code>
sudo yum -y install ntp
sudo systemctl start ntpd
date
</code>
  *  verify time is correct

  *  Set NUCs to PXE boot on wake-on-lan
  *  https://help.ubuntu.com/community/WakeOnLan
  *  In BIOS options (F2), Power tab, set "Wake on LAN from S4/S5" to "Power On - PXE Boot" and save (F10)
  *  Boot NUCs and note MAC addresses, so they can be included in the wakenodes.sh script referenced below
  *  install ether-wake if needed to test of wakenodes.sh
<code>
sudo yum -y install net-tools
</code>

  *  install git
<code>
sudo yum -y install git
cd ~
</code>

  *  clone genesis
<code>
git clone https://blsaws@gerrit.opnfv.org/gerrit/genesis
</code>

  *  (for testing, downloaded trozet's patch fork snapshot from https://gerrit.opnfv.org/gerrit/gitweb?p=genesis.git;a=commit;h=756ee8c81cfac9a69e8f67811429e63da9af6480 
<code>
curl "https://gerrit.opnfv.org/gerrit/gitweb?p=genesis.git;a=snapshot;h=756ee8c81cfac9a69e8f67811429e63da9af6480;sf=tgz" -o genesis-756ee8c.tar.gz
gzip -d genesis-756ee8c.tar.gz
tar -xvf genesis-756ee8c.tar
</code>

  *  modify to clone khaleesi from my fork (trozet=>blsaws) per the patches below
  *  note: if you want to use the wakenodes.sh script, you will need to fork my repo and mod wakenodes.sh for your MACs
<code>
vi ~/genesis-756ee8c/foreman/ci/bootstrap.sh
if ! git clone -b opnfv https://github.com/blsaws/khaleesi.git; then
</code>

  *  modify ~/genesis-756ee8c/foreman/ci/opnfv_ksgen_settings_no_HA.yml for my specific config
<code>
vi ~/genesis-756ee8c/foreman/ci/opnfv_ksgen_settings_no_HA.yml
# Jumphost1:
  # (for compute1:)
    name: oscompute1.{{ domain_name }}
    hostname: oscompute1.{{ domain_name }}
    short_name: oscompute1
    mac_address: "<compute1-mac>"
  # (for controller1:)
    name: oscontroller1.{{ domain_name }}
    hostname: oscontroller1.{{ domain_name }}
    short_name: oscontroller1
    mac_address: "<controller1-mac>"
    private_mac: "<controller1-mac>"
# Jumphost2:
  # (for compute1:)
    name: oscompute1.{{ domain_name }}
    hostname: oscompute1.{{ domain_name }}
    short_name: oscompute1
    mac_address: "<compute1-mac>"
  # (for controller1:)
    name: oscontroller1.{{ domain_name }}
    hostname: oscontroller1.{{ domain_name }}
    short_name: oscontroller1
    mac_address: "<controller1-mac>"
    private_mac: "<controller1-mac>"
</code>

  * clone my fork of trozet's khaleesi, updated with patches
  * it will later be cloned by the foreman vm, so these patches will be available in the foreman vm
<code>
cd /opt
sudo git clone -b opnfv https://github.com/blsaws/khaleesi.git
</code>

  * during initial debugging, the patches were manually created as below; later they were pulled from the repo fork after being committed
  * patch 1: add wakenodes.sh to root of khaleesi repo
    * alternative is to manually power-on the nodes, which will go into PXE-boot mode
<code>
sudo vi /opt/khaleesi/wakenodes.sh
# !/bin/bash
yum -y install net-tools
ether-wake <compute1-mac>
ether-wake <controller1-mac>
</code>

   * During initial debugging wakenodes.sh was copied to the shared folder for the foreman vm and later copied to the root of the cloned repo in the foreman vm.
     * (in jumphost) sudo cp /opt/khaleesi/wakenodes.sh /var/opt/opnfv/foreman_vm
     * (after foreman vm is up)
       * su; cd /var/opt/opnfv/foreman_vm; vagrant ssh; cp /vagrant/wakenodes.sh /opt/khaleesi/wakenodes.sh
  * patch 2: in main.yml add call to wakenodes.sh script as shown in http://docs.ansible.com/ansible/script_module.html
    * In khaleesi/roles/get_nodes/foreman/tasks/main.yml add call to node wakeup script after block "- name: Provision nodes"
<code>
sudo vi /opt/khaleesi/roles/get_nodes/foreman/tasks/main.yml 
- script: /opt/khaleesi/wakenodes.sh
</code>

    * During initial debugging main.yml was copied to the shared folder for the foreman vm and later copied to the cloned repo in the foreman vm.
      * (in jumphost) sudo cp /opt/khaleesi/roles/get_nodes/foreman/tasks/main.yml /var/opt/opnfv/foreman_vm/main.yml
      * (after foreman vm is up)
        * su; cd /var/opt/opnfv/foreman_vm; vagrant ssh; cp /vagrant/main.yml /opt/khaleesi/roles/get_nodes/foreman/tasks/main.yml
  * patch 3: in foreman.py skip IPMI related code in node bringup
    * In khaleesi/library/foreman.py exit early to avoid IPMI code
    * change "elif ipmi_host is None:" to "if ipmi_host is None:" and add module.exit before i
<code>
sudo vi /opt/khaleesi/library/foreman.py
# bryan_att modified to skip IPMI stuff
module.exit_json(changed=True, msg="Rebuilding Node")
# change elif to if so the module.exit is outside the previous if block
if ipmi_host is None:
</code>

    * During initial debugging foreman.py was copied to the shared folder and then to the foreman VM as above.
      * (in jumphost) sudo cp /opt/khaleesi/library/foreman.py /var/opt/opnfv/foreman_vm/
      * (after foreman vm is up)
        * su; cd /var/opt/opnfv/foreman_vm; vagrant ssh; cp /vagrant/foreman.py /opt/khaleesi/library/foreman.py

  * kickoff deploy.sh
<code>
cd ~/genesis-756ee8c/foreman/ci/
sudo ./deploy.sh -single_baremetal_nic enp0s25 -base_config /home/opnfv/genesis-756ee8c/foreman/ci/opnfv_ksgen_settings_no_HA.yml
</code>

  * if errors, before retrying wipe using clean.sh or
<code>
su
cd /var/opt/opnfv/foreman_vm
vagrant destroy -f
cd -
rm -rf /var/opt/opnfv
exit
rm /home/opnfv/.ssh/known_hosts
</code>

  * when you see "PASSED", login to controller node and setup bridge to external network for VMs (manual tasks needed for non-HA single NIC installs. for HA single-NIC installs this is handled already). 
<code>
vi /etc/neutron/plugin.ini
# add to end
[ovs]
bridge_mappings = physnet1:br-ex
# comment out "flat_networks =*" and add under it
flat_networks = physnet1
</code>

  * Restart Neutron
<code>
openstack-service restart neutron
</code>

  * Create /etc/sysconfig/network-scripts/ifcfg-br-ex with https://github.com/trozet/puppet-trystack/blob/quickstack/templates/br_ex.erb as template.
    * Note: the following assumes that Foreman assigned IP 192.168.1.204 to controller1. If different, use the IP assigned for the system you are installing, here and below.
<code>
vi /etc/sysconfig/network-scripts/ifcfg-br-ex
DEVICE=br-ex
DEVICETYPE=ovs
IPADDR=192.168.1.204
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
BOOTPROTO=static
ONBOOT=yes
TYPE=OVSBridge
PROMISC=yes
PEERDNS=no
</code>

  * Verify ovs is setup correctly
<code>
[root@oscontroller1 ~]# ovs-vsctl show

        fail_mode: secure
        Port br-int
            Interface br-int
    ovs_version: "2.3.1"
</code>

  * Modify /etc/sysconfig/network-scripts/ifcfg-enp0s25
<code>
vi /etc/sysconfig/network-scripts/ifcfg-enp0s25
NAME="enp0s25"
DEVICE="enp0s25"
ONBOOT=yes
NETBOOT=yes
(leave UUID line as is, replace rest with the below)
BOOTPROTO=static
TYPE=OVSPort
OVS_BRIDGE=br-ex
PROMISC=yes
IPV4_FAILURE_FATAL=no
PEERDNS=no
PEERROUTES=yes
</code>

  * Restart networking
<code>
systemctl restart network
</code>

  * On the jumphost, from Horizon / Project / Compute / Access & Security / API Access select "Download OpenStack RC file, transfer to the controller root home directory, then execute it.
<code>
vi admin-openrc.sh
(paste contents)
source admin-openrc.sh
</code>

  * Create external network and subnet using Neutron CLI
