==========================================
Conducting OVP Testing with Dovetail
==========================================

Overview
------------------------------

The Dovetail testing framework for OVP consists of two major parts: the testing client that
executes all test cases in a lab (vendor self-testing or a third party lab),
and the server system that is hosted by the OVP administrator to store and
view test results based on a web API. The following diagram illustrates
this overall framework.

.. image:: ../../../images/dovetail_online_mode.png
    :align: center
    :scale: 50%

Within the tester's lab, the Test Host is the machine where Dovetail executes all
automated test cases. As it hosts the test harness, the Test Host must not be part of
the System Under Test (SUT) itself.
The above diagram assumes that the tester's Test Host is situated in a DMZ, which
has internal network access to the SUT and external access via the public Internet.
The public Internet connection allows for easy installation of the Dovetail containers.
A singular compressed file that includes all the underlying results can be pulled from
the Test Host and uploaded to the OPNFV OVP server.
This arrangement may not be supported in some labs. Dovetail also supports an offline mode of
installation that is illustrated in the next diagram.

.. image:: ../../../images/dovetail_offline_mode.png
    :align: center
    :scale: 50%

In the offline mode, the Test Host only needs to have access to the SUT
via the internal network, but does not need to connect to the public Internet. This
user guide will highlight differences between the online and offline modes of
the Test Host. While it is possible to run the Test Host as a virtual machine,
this user guide assumes it is a physical machine for simplicity.

The rest of this guide will describe how to install the Dovetail tool as a
Docker container image, go over the steps of running the OVP test suite, and
then discuss how to view test results and make sense of them.

Readers interested
in using Dovetail for its functionalities beyond OVP testing, e.g. for in-house
or extended testing, should consult the Dovetail developer's guide for additional
information.

Installing Dovetail
--------------------

In this section, we describe the procedure to install Dovetail client tool on the Test Host.
The Test Host must have network access to the management network with access rights to
the Virtual Infrastructure Manager's API.

Checking the Test Host Readiness
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The Test Host must have network access to the Virtual Infrastructure Manager's API
hosted in the SUT so that the Dovetail tool can exercise the API from the Test Host.
It must also have ``ssh`` access to the Linux operating system
of the compute nodes in the SUT. The ``ssh`` mechanism is used by some test cases
to generate test events in the compute nodes. You can find out which test cases
use this mechanism in the test specification document.

We have tested the Dovetail tool on the following host operating systems. Other versions
or distributions of Linux may also work, but community support may be more available on
these versions.

- Ubuntu 16.04.2 LTS (Xenial) or 14.04 LTS (Trusty)
- CentOS-7-1611
- Red Hat Enterprise Linux 7.3
- Fedora 24 or 25 Server

Use of Ubuntu 16.04 is highly recommended, as it has been most widely employed during testing.
Non-Linux operating systems, such as Windows and Mac OS, have not been tested
and are not supported.

If online mode is used, the tester should also validate that the Test Host can reach
the public Internet. For example,

.. code-block:: bash

   $ ping www.opnfv.org
   PING www.opnfv.org (50.56.49.117): 56 data bytes
   64 bytes from 50.56.49.117: icmp_seq=0 ttl=48 time=52.952 ms
   64 bytes from 50.56.49.117: icmp_seq=1 ttl=48 time=53.805 ms
   64 bytes from 50.56.49.117: icmp_seq=2 ttl=48 time=53.349 ms
   ...


Or, if the lab environment does not allow ping, try validating it using HTTPS instead.

.. code-block:: bash

   $ curl https://www.opnfv.org
   <!doctype html>


   <html lang="en-US" class="no-js">
   <head>
   ...

Installing Prerequisite Packages on the Test Host
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The main prerequisite software for Dovetail are Python and Docker.

In the OVP test suite for the Danube release, Dovetail requires Python 2.7. Various minor 
versions of Python 2.7.x are known to work Dovetail, but there are no assurances. Python 3.x
is not supported at this time.

Use the following steps to check if the right version of python is already installed,
and if not, install it.

.. code-block:: bash

   $ python --version
   Python 2.7.6

If your Test Host does not have Python installed, or the version is not 2.7, you
should consult Python installation guides corresponding to the operating system
in your Test Host on how to install Python 2.7.

Dovetail does not work with Docker versions prior to 1.12.3. We have validated
Dovetail with Docker 17.03 CE. Other versions of Docker later than 1.12.3 may
also work, but community support may be more available on Docker 17.03 CE or greater.

.. code-block:: bash

   $ sudo docker version
   Client:
   Version:      17.03.1-ce
   API version:  1.27
   Go version:   go1.7.5
   Git commit:   c6d412e
   Built:        Mon Mar 27 17:10:36 2017
   OS/Arch:      linux/amd64

   Server:
   Version:      17.03.1-ce
   API version:  1.27 (minimum version 1.12)
   Go version:   go1.7.5
   Git commit:   c6d412e
   Built:        Mon Mar 27 17:10:36 2017
   OS/Arch:      linux/amd64
   Experimental: false

If your Test Host does not have Docker installed, or Docker is older than 1.12.3,
or you have Docker version other than 17.03 CE and wish to change,
you will need to install, upgrade, or re-install in order to run Dovetail.
The Docker installation process
can be more complex, you should refer to the official
Docker installation guide that is relevant to your Test Host's operating system.

The above installation steps assume that the Test Host is in the online mode. For offline
testing, use the following offline installation steps instead.

In order to install or upgrade Python offline, you may download packaged Python 2.7
for your Test Host's operating system on a connected host, copy the packge to
the Test Host, then install from that local copy.

In order to install Docker offline, download Docker static binaries and copy the
tar file to the Test Host, such as for Ubuntu14.04, you may follow the following link
to install,

.. code-block:: bash

   https://github.com/meetyg/docker-offline-install

Configuring the Test Host Environment
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The Test Host needs a few environment variables set correctly in order to access the
Openstack API required to drive the Dovetail tests. For convenience and as a convention,
we will also create a home directory for storing all Dovetail related config files and
results files:

.. code-block:: bash

   $ mkdir -p /home/dovetail
   $ export DOVETAIL_HOME=/home/dovetail

Here we set dovetail home directory to be ``/home/dovetail`` for an example.
Then create a directory named ``pre_config`` in this directory to store all
Dovetail related config files:

.. code-block:: bash

   $ mkdir -p ${DOVETAIL_HOME}/pre_config

Setting up Primary Configuration File
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

At this point, you will need to consult your SUT (Openstack) administrator to correctly set
the configurations in a file named ``env_config.sh``.
The Openstack settings need to be configured such that the Dovetail client has all the necessary
credentials and privileges to execute all test operations. If the SUT uses terms
somewhat differently from the standard Openstack naming, you will need to adjust
this file accordingly.

Create and edit the file ``${DOVETAIL_HOME}/pre_config/env_config.sh`` so that
all parameters are set correctly to match your SUT. Here is an example of what
this file should contain.

.. code-block:: bash

   $ cat ${DOVETAIL_HOME}/pre_config/env_config.sh

   # Project-level authentication scope (name or ID), recommend admin project.
   export OS_PROJECT_NAME=admin

   # For identity v2, it uses OS_TENANT_NAME rather than OS_PROJECT_NAME.
   export OS_TENANT_NAME=admin

   # Authentication username, belongs to the project above, recommend admin user.
   export OS_USERNAME=admin

   # Authentication password. Use your own password
   export OS_PASSWORD=xxxxxxxx

   # Authentication URL, one of the endpoints of keystone service. If this is v3 version,
   # there need some extra variables as follows.
   export OS_AUTH_URL='http://xxx.xxx.xxx.xxx:5000/v3'

   # Default is 2.0. If use keystone v3 API, this should be set as 3.
   export OS_IDENTITY_API_VERSION=3

   # Domain name or ID containing the user above.
   # Command to check the domain: openstack user show <OS_USERNAME>
   export OS_USER_DOMAIN_NAME=default

   # Domain name or ID containing the project above.
   # Command to check the domain: openstack project show <OS_PROJECT_NAME>
   export OS_PROJECT_DOMAIN_NAME=default

   # Special environment parameters for https.
   # If using https + cacert, the path of cacert file should be provided.
   # The cacert file should be put at $DOVETAIL_HOME/pre_config.
   export OS_CACERT=/path/to/pre_config/cacert.pem

   # If using https + no cacert, should add OS_INSECURE environment parameter.
   export OS_INSECURE=True


The OS_AUTH_URL variable is key to configure correctly, as the other admin services
are gleaned from the identity service. HTTPS should be configured in the SUT so the
final two variables should be uncommented. However, if SSL is disabled in the SUT, comment
out the OS_CACERT and OS_INSECURE variables. Ensure the '/path/to/pre_config' directory in
the above file matches the directory location of the cacert file for the OS_CACERT variable.

Export all these variables into environment by,

.. code-block:: bash

   $ source ${DOVETAIL_HOME}/pre_config/env_config.sh

The above line may be added to your .bashrc file for convenience when repeatedly using
Dovetail.

The next three sections outline additional configuration files used by Dovetail. The
tempest (tempest_conf.yaml) configuration file is required for executing the mandatory
osinterop test cases and the optional ipv6/tempest test cases. The HA (pod.yaml) configuration
file is required for the mandatory HA test cases and is also employed to collect SUT hardware
info. The hosts.yaml is optional for hostname/IP resolution.

Configuration for Running Tempest Test Cases (Mandatory)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The test cases in the test areas `osinterop` (OpenStack Interoperability tests),
`ipv6` and `tempest` are based on Tempest.  A SUT-specific configuration of
Tempest is required in order to run those test cases successfully.  The
corresponding SUT-specific configuration options must be supplied in the file
``$DOVETAIL_HOME/pre_config/tempest_conf.yaml``.

Create and edit file ``$DOVETAIL_HOME/pre_config/tempest_conf.yaml``.
Here is an example of what this file should contain.

.. code-block:: bash

   compute:
     # The minimum number of compute nodes expected.
     # This should be no less than 2 and no larger than the compute nodes the SUT actually has.
     min_compute_nodes: 2

     # Expected device name when a volume is attached to an instance.
     volume_device_name: vdb

Use the listing above at a minimum to execute the mandatory test areas.

Configuration for Running HA Test Cases (Mandatory)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The mandatory HA test cases require OpenStack controller node info. It must include the node's
name, role, ip, as well as the user and key_filename or password to login to the node. Users
must create the file ``${DOVETAIL_HOME}/pre_config/pod.yaml`` to store the info. This file is
also used as basis to collect SUT hardware information that is stored alongside results and
uploaded to the OVP web portal. The SUT hardware information can be viewed within the
'My Results' view in the OVP web portal by clicking the SUT column 'info' link. In order to
collect SUT hardware information holistically, ensure this file has an entry for each of
the controller and compute nodes within the SUT.

Below is a sample with the required syntax when password is employed by the controller.

.. code-block:: bash

   nodes:
   -
       # This can not be changed and must be node1.
       name: node1

       # This must be controller.
       role: Controller

       # This is the install IP of a controller node, which is the haproxy primary node
       ip: xx.xx.xx.xx

       # User name of this node. This user must have sudo privileges.
       user: root

       # Password of the user.
       password: root

Besides the 'password', a 'key_filename' entry can be provided to login to the controller node.
Users need to create file ``$DOVETAIL_HOME/pre_config/id_rsa`` to store the private key.
A sample is provided below to show the required syntax when using a key file.

.. code-block:: bash

   nodes:
   -
       name: node1
       role: Controller
       ip: 10.1.0.50
       user: root

       # Private key of this node. It must be /root/.ssh/id_rsa
       # Dovetail will move the key file from $DOVETAIL_HOME/pre_config/id_rsa
       # to /root/.ssh/id_rsa of Yardstick container
       key_filename: /root/.ssh/id_rsa

Under nodes, repeat entries for name, role, ip, user and password or key file for each of the
controller/compute nodes that comprise the SUT. Use a '-' to separate each of the entries.
Specify the value for the role key to be either 'Controller' or 'Compute' for each node.

Configuration of Hosts File (Optional)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If your SUT uses a hosts file to translate hostnames into the IP of OS_AUTH_URL, then you need
to provide the hosts info in a file ``$DOVETAIL_HOME/pre_config/hosts.yaml``.

Create and edit file ``$DOVETAIL_HOME/pre_config/hosts.yaml``. Below is an example of what
this file should contain. Note, that multiple hostnames can be specified for each IP address,
as shown in the generic syntax below the example.

.. code-block:: bash

   $ cat ${DOVETAIL_HOME}/pre_config/hosts.yaml

   ---
   hosts_info:
     192.168.141.101:
       - ha-vip

     <ip>:
       - <hostname1>
       - <hostname2>


Installing Dovetail on the Test Host
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The Dovetail project maintains a Docker image that has Dovetail test tools preinstalled.
This Docker image is tagged with versions. Before pulling the Dovetail image, check the
OPNFV's OVP web page first to determine the right tag for OVP testing.

Online Test Host
""""""""""""""""

If the Test Host is online, you can directly pull Dovetail Docker image and download Ubuntu
and Cirros images. All other dependent docker images will automatically be downloaded. The
Ubuntu and Cirros images are used by Dovetail for image creation and VM instantiation within
the SUT.

.. code-block:: bash

   $ wget -nc http://artifacts.opnfv.org/sdnvpn/ubuntu-16.04-server-cloudimg-amd64-disk1.img -P ${DOVETAIL_HOME}/pre_config
   $ wget -nc http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img -P ${DOVETAIL_HOME}/pre_config

   $ sudo docker pull opnfv/dovetail:ovp.1.0.0
   ovp.1.0.0: Pulling from opnfv/dovetail
   30d541b48fc0: Pull complete

   Status: Downloaded newer image for opnfv/dovetail:ovp.1.0.0

An example of the <tag> is *ovp.1.0.0*.

Offline Test Host
"""""""""""""""""

If the Test Host is offline, you will need to first pull the Dovetail Docker image, and all the
dependent images that Dovetail uses, to a host that is online. The reason that you need
to pull all dependent images is because Dovetail normally does dependency checking at run-time
and automatically pulls images as needed, if the Test Host is online. If the Test Host is
offline, then all these dependencies will need to be manually copied.

.. code-block:: bash

   $ sudo docker pull opnfv/dovetail:ovp.1.0.0
   $ sudo docker pull opnfv/functest:ovp.1.0.0
   $ sudo docker pull opnfv/yardstick:danube.3.2
   $ sudo docker pull opnfv/testapi:ovp.1.0.0
   $ sudo docker pull mongo:3.2.1
   $ sudo wget -nc http://artifacts.opnfv.org/sdnvpn/ubuntu-16.04-server-cloudimg-amd64-disk1.img -P {ANY_DIR}
   $ sudo wget -nc http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img -P {ANY_DIR}

Once all these images are pulled, save the images, copy to the Test Host, and then load
the Dovetail image and all dependent images at the Test Host. The final two lines above are
to obtain the test images for transfer to the Test Host.

At the online host, save the images with the command below.

.. code-block:: bash

   $ sudo docker save -o dovetail.tar opnfv/dovetail:ovp.1.0.0 \
     opnfv/functest:ovp.1.0.0 opnfv/yardstick:danube.3.2 \
     opnfv/testapi:ovp.1.0.0 mongo:3.2.1

The command above creates a dovetail.tar file with all the images, which can then be copied
to the Test Host. To load the Dovetail images on the Test Host execute the command below.

.. code-block:: bash

   $ sudo docker load --input dovetail.tar

Now check to see that all Docker images have been pulled or loaded properly.

.. code-block:: bash

   $ sudo docker images
   REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
   opnfv/functest      ovp.1.0.0           e2b286547478        6 weeks ago         1.26 GB
   opnfv/dovetail      ovp.1.0.0           5d25b289451c        8 days ago          516MB
   opnfv/yardstick     danube.3.2          df830d5c2cb2        6 weeks ago         1.21 GB
   opnfv/testapi       ovp.1.0.0           05c6d5ebce6c        2 months ago        448 MB
   mongo               3.2.1               7e350b877a9a        19 months ago       317 MB

After copying and loading the Dovetail images at the Test Host, also copy the test images
(Ubuntu, Cirros) to the Test Host. Copy image ubuntu-16.04-server-cloudimg-amd64-disk1.img
to ``${DOVETAIL_HOME}/pre_config/``. Copy image cirros-0.3.5-x86_64-disk.img to
``${DOVETAIL_HOME}/pre_config/``.

Starting Dovetail Docker
------------------------

Regardless of whether you pulled down the Dovetail image directly online, or loaded from
a static image tar file, you are now ready to run Dovetail. Use the command below to
create a Dovetail container and get access to its shell.

.. code-block:: bash

   $ sudo docker run --privileged=true -it \
             -e DOVETAIL_HOME=$DOVETAIL_HOME \
             -v $DOVETAIL_HOME:$DOVETAIL_HOME \
             -v /var/run/docker.sock:/var/run/docker.sock \
             opnfv/dovetail:<tag> /bin/bash

The ``-e`` option sets the DOVETAIL_HOME environment variable in the container and the
``-v`` options map files in the Test Host to files in the container. The latter option
allows the Dovetail container to read the configuration files and write result files into
DOVETAIL_HOME on the Test Host. The user should be within the Dovetail container shell,
once the command above is executed.

Build Local DB and Testapi Services
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The steps in this section only need to be executed if the user plans on storing consolidated
results on the Test Host that can be uploaded to the OVP portal.

Dovetail needs to build the local DB and testapi service for storing and reporting results
to the OVP web portal. There is a script in the Dovetail container for building the local DB.
The ports 27017 and 8000 are used by the DB and testapi respectively. If the Test Host is
using these ports for existing services, to avoid conflicts, remap the ports to values that
are unused. Execute the commands below in the Dovetail container to remap ports, as required.
This step can be skipped if there are no port conflicts with the Test Host.

.. code-block:: bash

   $ export mongodb_port=<new_DB_port>
   $ export testapi_port=<new_testapi_port>

Within the Dovetail container, navigate to the directory and execute the shell script using
the commands below to build the local DB and testapi services.

.. code-block:: bash

   $ cd /home/opnfv/dovetail/dovetail/utils/local_db/
   $ ./launch_db.sh

To validate the DB and testapi services are running successfully, navigate to the URL
``http://<test_host_ip>:<testapi_port>/api/v1/results``, substituting within the URL
the IP address of the Test Host and the testapi port number. If you can access this URL
successfully, the services are up and running.

Running the OVP Test Suite
----------------------------

All or a subset of the available tests can be executed at any location within the
Dovetail container prompt. You can refer to :ref:`cli-reference`
for the details of the CLI.


.. code-block:: bash

   $ dovetail run --testsuite <test-suite-name>

The '--testsuite' option is used to control the set of tests intended for execution
at a high level. For the purposes of running the OVP test suite, the test suite name follows
the following format, ``ovp.<major>.<minor>.<patch>``. The latest and default test suite is
 ovp.1.0.0.

.. code-block:: bash

   $ dovetail run

This command is equal to

.. code-block:: bash

   $ dovetail run --testsuite ovp.1.0.0

Without any additional options, the above command will attempt to execute all mandatory and
optional test cases. To restrict the breadth of the test scope, test areas can also be
specified using the '--testarea' option. The test area can be specified broadly using arguments
'mandatory' and 'optional'. The mandatory tests can be narrowed further using test area arguments
'osinterop', 'vping' and 'ha'. The optional tests can be narrowed further using test area
arguments 'ipv6', 'sdnvpn' and 'tempest'.

.. code-block:: bash

   $ dovetail run --testarea mandatory

By default, results are stored in local files on the Test Host at ``$DOVETAIL_HOME/results``.
Each time the 'dovetail run' command is executed, the results in the aforementioned directory
are overwritten. To create a singular compressed result file for upload to the OVP portal or
for archival purposes, the results need to pushed to the local DB. This can be achieved by
using the '--report' option with an argument syntax as shown below. Note, that the Test Host
IP address and testapi port number must be substituted with appropriate values.

.. code-block:: bash

   $ dovetail run --report http://<test_host_ip>:<testapi_port>/api/v1/results

If the Test Host is offline, ``--offline`` should be added to support running with
local resources.

.. code-block:: bash

   $ dovetail run --offline --report http://<test_host_ip>:<testapi_port>/api/v1/results

Below is an example of running the entire mandatory test area and the creation of the compressed
result file on the Test Host.

.. code-block:: bash

   $ dovetail run --offline --testarea mandatory --report http://192.168.135.2:8000/api/v1/results
   2017-09-29 07:00:55,718 - run - INFO - ================================================

   2017-09-29 07:20:42,434 - run - INFO - >>[testcase]: dovetail.ha.tc001
   ...

When test execution is complete, a tar file with all result and log files is written in
``$DOVETAIL_HOME`` on the Test Host. An example filename is
``${DOVETAIL_HOME}/logs_20180105_0858.tar.gz``. The file is named using a
timestamp that follows the convention 'YearMonthDay-HourMinute'. In this case, it was generated
at 08:58 on January 5th, 2018. This tar file is used to upload to the OVP portal.


Making Sense of OVP Test Results
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When a tester is performing trial runs, Dovetail stores results in local files on the Test
Host by default within the directory specified below. Note, that if the '--report' option
is used to execute tests, results are written to results.json and the files functest_results.txt
and dovetail_ha_tcXXX.out will not be created.


.. code-block:: bash

       cd $DOVETAIL_HOME/results

#. Local file

   * Log file: dovetail.log

     * Review the dovetail.log to see if all important information has been captured
       - in default mode without DEBUG.

     * Review the results.json to see all results data including criteria for PASS or FAIL.

   * Example: OpenStack Interoperability test cases

     * Can see the log details in ``osinterop_logs/dovetail.osinterop.tc001.log``,
       which has the passed, skipped and failed test cases results.

     * The skipped test cases have the reason for the users to see why these test cases skipped.

     * The failed test cases have rich debug information for the users to see why these test cases fail.

   * Example: vping test case example

     * Its log is stored in dovetail.log.

     * Its result is stored in functest_results.txt.

   * Example: ha test case example

     * Its log is stored in dovetail.log.

     * Its result is stored in dovetail_ha_tcXXX.out.

   * Example: ipv6, sdnvpn and tempest test cases examples

     * Can see the log details in ``ipv6_logs/dovetail.ipv6.tcXXX.log``,
       ``sdnvpn_logs/dovetail.sdnvpn.tcXXX.log`` and ``tempest_logs/dovetail.tempest.tcXXX.log``,
       respectively. They all have the passed, skipped and failed test cases results.

OVP Portal Web Interface
------------------------

The OVP portal is a public web interface for the community to collaborate on results
and to submit results for official OPNFV compliance verification. The portal can be used as a
resource by users and testers to navigate and inspect results more easily than by manually
inspecting the log files. The portal also allows users to share results in a private manner
until they are ready to submit results for peer community review.

   * Web Site URL

     * https://verified.opnfv.org

   * Sign In / Sign Up Links

     * Accounts are exposed through Linux Foundation or OpenStack account credentials.

     * If you already have a Linux Foundation ID, you can sign in directly with your ID.

     * If you do not have a Linux Foundation ID, you can sign up for a new one using 'Sign Up'

   * My Results Tab

     * This is the primary view where most of the workflow occurs.

     * This page lists all results uploaded by you after signing in.

     * You can also upload results on this page with the two steps below.

     * Obtain results tar file located at ``${DOVETAIL_HOME}/``, example ``logs_20180105_0858.tar.gz``

     * Use the *Choose File* button where a file selection dialog allows you to choose your result
       file from the hard-disk. Then click the *Upload* button and see a results ID once your
       upload succeeds.

     * Results are status 'private' until they are submitted for review.

     * Use the *Operation* column drop-down option 'submit to review', to expose results to
       OPNFV community peer reviewers. Use the 'withdraw submit' option to reverse this action.

     * Use the *Operation* column drop-down option 'share with' to share results with other
       users by supplying either the login user ID or the email address associated with
       the share target account. The result is exposed to the share target but remains private
       otherwise.

   * Profile Tab

     * This page shows your account info after you sign in.

Updating Dovetail or a Test Suite
---------------------------------

Follow the instructions in section `Installing Dovetail on the Test Host`_ and
`Running the OVP Test Suite`_ by replacing the docker images with new_tags,

.. code-block:: bash

   sudo docker pull opnfv/dovetail:<dovetail_new_tag>
   sudo docker pull opnfv/functest:<functest_new_tag>
   sudo docker pull opnfv/yardstick:<yardstick_new_tag>

This step is necessary if dovetail software or the OVP test suite have updates.
