 Abstract
 ========
-This document provides information on how to configure required
-components during the installation of the platform.
+This document provides information on how to install the OpenDayLigh SFC
+features in OPNFV with the use of os_odl-l2_sfc-(no)ha scenario.
+
+SFC feature desciription
+========================
+For details of the scenarios and their provided capabilities refer to
+the scenario description documents:
+
+- http://artifacts.opnfv.org/sfc/colorado/docs/scenarios_os-odl_l2-sfc-ha/index.html
+
+- http://artifacts.opnfv.org/sfc/colorado/docs/scenarios_os-odl_l2-sfc-noha/index.html
+
+
+The SFC feature enables creation of Service Fuction Chains - an ordered list
+of chained network funcions (e.g. firewalls, NAT, QoS)
+
+The SFC feature in OPNFV is implemented by 3 major components:
+
+- OpenDayLight SDN controller
 
-Pre-configuration activites
-===========================
-List the information and activities needed as pre configuration.
+- Tacker: Generic VNF Manager (VNFM) and a NFV Orchestrator (NFVO)
 
-Feature configuration
+- OpenvSwitch: The Service Function Forwarder(s)
+
+Hardware requirements
 =====================
-List the steps needed for the configuration of <feature> and <components> of the scenario.
 
+The SFC scenarios can be deployed on a bare-metal OPNFV cluster or on a
+virtual environment on a single host.
+
+Bare metal deployment on (OPNFV) Pharos lab
+-------------------------------------------
+Hardware requirements for bare-metal deployments of the OPNFV infrastructure
+are given by the Pharos project. The Pharos project provides an OPNFV
+hardware specification for configuring your hardware:
+http://artifacts.opnfv.org/pharos/docs/pharos-spec.html
+
+
+Virtual deployment
+------------------
+To perform a virtual deployment of an OPNFV SFC scenario on a single host,
+that host has to meet the following hardware requirements:
+
+- SandyBridge compatible CPU with virtualization support
+
+- capable to host 5 virtual cores (5 phisical ones at least)
+
+- 8-12 GBytes RAM for virtual hosts (controller, compute), 48GByte at least
+
+- 128 GiBiBytes room on disk for each virtual host (controller, compute) +
+  64GiBiBytes for fuel master, 576 GiBiBytes at least
+
+- Ubuntu Trusty Tahr - 14.04(.5) server operating system with at least ssh
+  service selected at installation.
+
+- Internet Connection (preferably http proxyless)
+
+
+Pre-configuration activites - Preparing the host to install Fuel by script
+==========================================================================
+.. Not all of these options are relevant for all scenario's.  I advise following the
+.. instructions applicable to the deploy tool used in the scenario.
+
+Before starting the installation of the SFC scenarios some preparation of the
+machine that will host the Colorado Fuel cluster must be done.
+
+Installation of required packages
+---------------------------------
+To be able to run the installation of the basic OPNFV fuel installation the
+Jumphost (or the host which serves the VMs for the virtual deployment) needs to
+install the following packages:
+::
+
+ sudo apt-get install -y git make curl libvirt-bin libpq-dev qemu-kvm \
+                         qemu-system tightvncserver virt-manager sshpass \
+                         fuseiso genisoimage blackbox xterm python-pip \
+                         python-git python-dev python-oslo.config \
+                         python-pip python-dev libffi-dev libxml2-dev \
+                         libxslt1-dev libffi-dev libxml2-dev libxslt1-dev \
+                         expect curl python-netaddr p7zip-full
+
+ sudo pip install GitPython pyyaml netaddr paramiko lxml scp \
+                  scp pycrypto ecdsa debtcollector netifaces enum
+
+During libvirt install the user is added to the libvirtd group, so you have to
+logout then login back again
+
+
+Download the installer source code and artifact
+-----------------------------------------------
+To be able to install the scenario os_odl-l2_sfc-(no)ha one can follow the way
+CI is deploying the scenario.
+First of all the opnfv-fuel repository needs to be cloned:
+::
+
+ git clone -b 'stable/colorado' ssh://<user>@gerrit.opnfv.org:29418/fuel
+
+This command copies the whole colorado branch of repository fuel.
+
+Now download the appropriate OPNFV Fuel ISO into an appropriate folder:
+::
+
+ wget http://artifacts.opnfv.org/fuel/colorado/opnfv-colorado.1.0.iso
+
+The exact name of the ISO image may change.
+Check https://www.opnfv.org/opnfv-colorado-fuel-users to get the latest ISO.
+
+Simplified scenario deployment procedure using Fuel
+===================================================
+
+This section describes the installation of the os-odl-l2_sfc or
+os-odl-l2_sfc-noha OPNFV reference platform stack across a server cluster
+or a single host as a virtual deployment.
+
+Scenario Preparation
+--------------------
+dea.yaml and dha.yaml need to be copied and changed according to the
+lab-name/host where you deploy.
+Copy the full lab config from:
+::
+
+ cp <path-to-opnfv-fuel-repo>/deploy/config/labs/devel-pipeline/elx \
+    <path-to-opnfv-fuel-repo>/deploy/config/labs/devel-pipeline/<your-lab-name>
+
+Add at the bottom of dha.yaml
+::
+
+ disks:
+   fuel: 64G
+   controller: 128G
+   compute: 128G
+
+ define_vms:
+   controller:
+     vcpu:
+       value: 2
+     memory:
+       attribute_equlas:
+         unit: KiB
+       value: 12521472
+     currentMemory:
+       attribute_equlas:
+         unit: KiB
+       value: 12521472
+   compute:
+     vcpu:
+       value: 2
+     memory:
+       attribute_equlas:
+         unit: KiB
+       value: 8388608
+     currentMemory:
+       attribute_equlas:
+         unit: KiB
+       value: 8388608
+   fuel:
+     vcpu:
+       value: 2
+     memory:
+       attribute_equlas:
+         unit: KiB
+       value: 2097152
+     currentMemory:
+       attribute_equlas:
+         unit: KiB
+       value: 2097152
+
+Check if the default settings in dea.yaml are in line with your intentions
+and make changes as required.
+
+Installation procedures
+-----------------------
+
+We state here several alternatives.
+First, we describe methods that are based on the use of the deploy.sh script,
+what is used by the OPNFV CI system and can be found in the Fuel repository.
+
+In addition, the SFC feature can also be configured manually in the Fuel GUI
+what we will show in the last subsection.
+
+Before starting any of the following procedures, go to
+::
+
+ cd <opnfv-fuel-repo>/ci
+
+Full automatic virtual deployment, High Availablity mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This example will deploy the high-availability flavor of SFC scenario
+os_odl-l2_sfc-ha in a fully automatic way, i.e. all installation steps
+(Fuel server installation, configuration, node discovery and platform
+deployment) will take place without any further prompt for user input.
+::
+
+ sudo bash ./deploy.sh -b file://<path-to-opnfv-fuel-repo>/config/ -l devel-pipeline -p <your-lab-name>
+ -s os_odl-l2_sfc-ha -i file://<path-to-fuel-iso>
+
+Full automatic virtual deployment, non HIGH Availablity mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following command will deploy the SFC scenario with non-high-availability
+flavor (note the  different scenario name for the -s switch). Otherwise it
+does the same as described above.
+::
+
+ sudo bash ./deploy.sh -b file://<path-to-opnfv-fuel-repo>/config/ -l devel-pipeline -p <your-lab-name>
+ -s os_odl-l2_sfc-noha -i file://<path-to-fuel-iso>
+
+Automatic Fuel installation and manual scenario deployment
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A useful alternative to the full automatic procedure is to only deploy the Fuel host and to run host selection, role assignment and SFC scenario configuration manually.
+::
+
+ sudo bash ./deploy.sh -b file://<path-to-opnfv-fuel-repo>/config/ -l devel-pipeline -p <your-lab-name> -s os_odl-l2_sfc-ha -i file://<path-to-fuel-iso> -e
+
+With -e option the installer will skip environment deployment, so an user
+can do some modification before the scenario is really deployed. Another
+useful option is the -f option which deploys the scenario using an existing
+Fuel host.
+
+The result of this installation is a well configured Fuel sever. The use of
+the deploy button on Fuel dashboard can initiate the deployment. A user may
+perform manual post-configuration as well.
+
+Feature configuration on existing Fuel
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If a Fuel server is already provisioned but the fuel plugins for Opendaylight,
+Openvswitch are not provided install them by:
+::
+
+ cd /opt/opnfv/
+ fuel plugins --install fuel-plugin-ovs-*.noarch.rpm
+ fuel plugins --install opendaylight-*.noarch.rpm
+
+If plugins are installed and you want to update them use --force flag.
+
+Note that One may inject other - Colorado compatible - plugins to the Fuel
+Master host using the command scp:
+
+scp <plugin>.rpm root@10.20.0.2:<plugin>.rpm
+
+Now the feature can be configured. Create a new environment with
+Networking Setup:"OpenDayLight with tunneling segmentation". Then go to
+settings/other and check "OpenDaylight plugin, SFC enabled",
+"Install Openvswitch with NSH/DPDK, with NSH enabled". During node provision
+remember assign the OpenDayLight role to the (primary)controller
+
+Now the deploy button on fuel dashboard can be used to deploy the environment.
