+vSwitchPerf test suites userguide
+---------------------------------
General
--------
+^^^^^^^
VSPERF requires a traffic generators to run tests, automated traffic gen
support in VSPERF includes:
<http://artifacts.opnfv.org/vswitchperf/docs/configguide/trafficgen.html>`__
VSPERF Installation
---------------------
+^^^^^^^^^^^^^^^^^^^
+
To see the supported Operating Systems, vSwitches and system requirements,
please follow the `installation instructions
<http://artifacts.opnfv.org/vswitchperf/docs/configguide/installation.html>`__ to
install.
Traffic Generator Setup
------------------------
+^^^^^^^^^^^^^^^^^^^^^^^
+
Follow the `Traffic generator instructions
<http://artifacts.opnfv.org/vswitchperf/docs/configguide/trafficgen.html>`__ to
install and configure a suitable traffic generator.
Cloning and building src dependencies
--------------------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In order to run VSPERF, you will need to download DPDK and OVS. You can
do this manually and build them in a preferred location, OR you could
$ make clobber
Configure the ``./conf/10_custom.conf`` file
---------------------------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
The ``10_custom.conf`` file is the configuration file that overrides
default configurations in all the other configuration files in ``./conf``
The supplied ``10_custom.conf`` file **MUST** be modified, as it contains
the custom configuration value.
Using a custom settings file
-----------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If your ``10_custom.conf`` doesn't reside in the ``./conf`` directory
of if you want to use an alternative configuration file, the file can
3. Configuration file(s)
vloop_vnf
----------
+^^^^^^^^^
+
vsperf uses a VM called vloop_vnf for looping traffic in the PVP and PVVP
deployment scenarios. The image can be downloaded from
`<http://artifacts.opnfv.org/>`__.
Alternatively you can use your own QEMU image.
l2fwd Kernel Module
--------------------
+^^^^^^^^^^^^^^^^^^^
+
A Kernel Module that provides OSI Layer 2 Ipv4 termination or forwarding with
support for Destination Network Address Translation (DNAT) for both the MAC and
IP addresses. l2fwd can be found in <vswitchperf_dir>/src/l2fwd
Executing tests
----------------
+^^^^^^^^^^^^^^^
Before running any tests make sure you have root permissions by adding
the following line to /etc/sudoers:
$ ./vsperf --help
Executing Vanilla OVS tests
-----------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
1. If needed, recompile src for all OVS variants
Executing PVP and PVVP tests
-----------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
To run tests using vhost-user as guest access method:
1. Set VHOST_METHOD and VNF of your settings file to:
$ ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf
Executing PVP tests using Vanilla OVS
--------------------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
To run tests using Vanilla OVS:
1. Set the following variables:
or use --test-param
- ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf
- --test-param "vanilla_tgen_tx_ip=n.n.n.n;
- vanilla_tgen_tx_mac=nn:nn:nn:nn:nn:nn"
+ $ ./vsperf --conf-file=<path_to_custom_conf>/10_custom.conf
+ --test-param "vanilla_tgen_tx_ip=n.n.n.n;
+ vanilla_tgen_tx_mac=nn:nn:nn:nn:nn:nn"
2. If needed, recompile src for all OVS variants
$ ./vsperf --conf-file<path_to_custom_conf>/10_custom.conf
Selection of loopback application for PVP and PVVP tests
---------------------------------------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
To select loopback application, which will perform traffic forwarding
inside VM, following configuration parameter should be configured:
will fail. Guest loopback application is set to 'testpmd' by default.
Code change verification by pylint
-----------------------------------
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
Every developer participating in VSPERF project should run
pylint before his python code is submitted for review. Project
specific configuration for pylint is available at 'pylint.rc'.
$ pylint --rcfile ./pylintrc ./vsperf
GOTCHAs:
---------
+^^^^^^^^
OVS with DPDK and QEMU
~~~~~~~~~~~~~~~~~~~~~~~
+
If you encounter the following error: "before (last 100 chars):
'-path=/dev/hugepages,share=on: unable to map backing store for
hugepages: Cannot allocate memory\r\n\r\n" with the PVP or PVVP
VSWITCHD_DPDK_ARGS = ['-c', '0x4', '-n', '4', '--socket-mem 1024,0']
