======================
Installing vswitchperf
======================
Supported Operating Systems
---------------------------
* CentOS 7
* Fedora 20
* Fedora 21
* Fedora 22
* Ubuntu 14.04
Supported vSwitches
-------------------
The vSwitch must support Open Flow 1.3 or greater.
* OVS (built from source).
* OVS with DPDK (built from source).
Supported Hypervisors
---------------------
* Qemu version 2.3.
Available VNFs
--------------
A simple VNF that forwards traffic through a VM, using:
* DPDK testpmd
* Linux Brigde
* custom l2fwd module
The VM image can be downloaded from:
http://artifacts.opnfv.org/vswitchperf/vloop-vnf-ubuntu-14.04_20151216.qcow2
Other Requirements
------------------
The test suite requires Python 3.3 and relies on a number of other
packages. These need to be installed for the test suite to function.
Installation of required packages, preparation of Python 3 virtual
environment and compilation of OVS, DPDK and QEMU is performed by
script **systems/build_base_machine.sh**. It should be executed under
user account, which will be used for vsperf execution.
**Please Note**: Password-less sudo access must be configured for given
user account before script is executed.
Execution of installation script:
.. code:: bash
$ cd systems
$ ./build_base_machine.sh
**Please Note**: you don't need to go into any of the systems subdirectories,
simply run the top level **build_base_machine.sh**, your OS will be detected
automatically.
Script **build_base_machine.sh** will install all the vsperf dependencies
in terms of system packages, Python 3.x and required Python modules.
In case of CentOS 7 it will install Python 3.3 from an additional repository
provided by Software Collections (`a link`_). Installation script will also
use `virtualenv`_ to create a vsperf virtual environment, which is isolated
from the default Python environment. This environment will reside
in a directory called **vsperfenv** in $HOME.
You will need to activate the virtual environment every time you start a
new shell session. Its activation is specific to your OS:
CentOS 7
========
.. code:: bash
$ scl enable python33 bash
$ cd $HOME/vsperfenv
$ source bin/activate
Fedora and Ubuntu
=================
.. code:: bash
$ cd $HOME/vsperfenv
$ source bin/activate
Working Behind a Proxy
======================
If you're behind a proxy, you'll likely want to configure this before
running any of the above. For example:
.. code:: bash
export http_proxy=proxy.mycompany.com:123
export https_proxy=proxy.mycompany.com:123
.. _a link: http://www.softwarecollections.org/en/scls/rhscl/python33/
.. _virtualenv: https://virtualenv.readthedocs.org/en/latest/
