How to set up environment

Prerequsite

Please prepare four VMs or host machines with the following specification

No	usage	CPU	Memory	Disk
1	Openstack Controller & Network Node	4 Core	8 GB	100GB
2	ONOS Controller	2 Core	4 GB	100GB
3	Compute Node	1 Core	2 GB	100GB
4	Compute Node	1 Core	2 GB	100GB

Set up Control node (and network node)

Install devstack on the Openstack Controller node

$ git clone git://github.com/openstack-dev/devstack.git

Creates local.conf file using the following options

[[local|localrc]]
HOST_IP=1.1.1.1 
SERVICE_HOST=1.1.1.1  
RABBIT_HOST=1.1.1.1  
DATABASE_HOST=1.1.1.1  
Q_HOST=1.1.1.1  

ADMIN_PASSWORD=nova
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
SERVICE_TOKEN=$ADMIN_PASSWORD

DATABASE_TYPE=mysql

* The IP address 1.1.1.1 needs to be changed to your host IP address for Openstack controller. Here control node and network nodes are the same.
* You can choose a different admin password if you want.
* If you installed the onos ml2 plugin in a different place, you need to change the Q_PLUGIN_EXTRA_CONF_PATH properly.

Install onos ml2 plugin

 $ git clone https://github.com/openstack/networking-onos.git
 $ cd networking-onos
 ~/networking-onos$ sudo python setup.py install

If you find the following error, please install python-setuptools using apt-get.

Traceback (most recent call last):
  File "setup.py", line 17, in <module>
    import setuptools
ImportError: No module named setuptools

$ sudo apt-get install python-setuptools

Configure the onos ml2 plugin by editing the conf_onos.ini file in networking-onos/etc folder, which is just created

#Configuration options for ONOS driver

[onos]
# (StrOpt) ONOS ReST interface URL. This is a mandatory field.
url_path = http://ONOS_HOST_IP:8181/onos/openstackswitching

# (StrOpt) Username for authentication. This is a mandatory field.
username = onos

# (StrOpt) Password for authentication. This is a mandatory field.
password = rocks

You need to set the proper IP address for ONOS controller in ONOS_HOST_IP

Set up devstack

~/devstack$ ./stack.sh

It would take quite long up to 1 hour depending on the network status and host performance. If it is setup correctly, you will see the following message.

.............
This is your host IP address:1.1.1.1
This is your host IPv6 address: ::1
Horizon is now available at http://1.1.1.1/dashboard
Keystone is serving at http://1.1.1.1:5000/
The default users are: admin and demo
The password: nova
2015-12-03 05:49:10.116 | stack.sh completed in 264 seconds.

Please check if you can log in to the dashboard with the users.

Set up Compute node

Install Openvswitch

Even though any version higher than 2.0 would work, but we have tested with 2.3.2.

$ wget http://openvswitch.org/releases/openvswitch-2.3.2.tar.gz
$ tar xzvf openvswitch-2.3.2.tar.gz
$ cd openvswitch-2.3.2/
~/openvswitch-2.3.2$ ./configure
~/openvswitch-2.3.2$ make
~/openvswitch-2.3.2$ sudo make install
~/openvswitch-2.3.2$ sudo modprobe openvswitch

You can check if openvswitch is loaded properly

~/openvswitch-2.3.2$ sudo lsmod
Module                  Size  Used by
openvswitch            71004  0 
vxlan                  37619  1 openvswitch
ip_tunnel              23768  1 vxlan
gre                    13796  1 openvswitch
libcrc32c              12644  1 openvswitch

Set up OVS
Please see the following link for detail, but here are the simple way to set up the OVS.
https://github.com/openvswitch/ovs/blob/master/INSTALL.md

~/openvswitch-2.3.2$ mkdir -p /usr/local/etc/openvswitch
~/openvswitch-2.3.2$ sudo ovsdb-tool create /usr/local/etc/openvswitch/conf.db vswitchd/vswitch.ovsschema
~/openvswitch-2.3.2$ sudo ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \
                     --remote=db:Open_vSwitch,Open_vSwitch,manager_options \
                     --private-key=db:Open_vSwitch,SSL,private_key \
                     --certificate=db:Open_vSwitch,SSL,certificate \
                     --bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert \
                     --pidfile --detach
~/openvswitch-2.3.2$ sudo ovs-vsctl --no-wait init
~/openvswitch-2.3.2$ sudo ovs-vswitchd --pidfile --detach
