Build VMTP Docker Image
-----------------------
Build the VMTP Docker Image
---------------------------
The VMTP Docker images are published in the DockerHub berrypatch repository:
`<https://hub.docker.com/r/berrypatch/vmtp/>`_
Two files are used to build the Docker image: *Dockerfile* and *.dockerignore*. The former provides all the build instructions while the latter provides the list of files/directories that should not be copied to the Docker image.
In order to make the Docker image clean, remove all auto generated files from the root of your workspace first. It is strongly recommeneded to simply pull a new one from GitHub/StackForge. Specify the image name and the tag, and feed them to docker build. Examples to build the image with name "$USER/vmtp", tag "2.0.0" and "latest"::
In order to make the Docker image clean, remove all auto generated files from the root of your workspace first. It is strongly recommeneded to simply pull a new one from GitHub/OPenStack. Specify the image name and the tag, and feed them to docker build.
The tag should be an existing git tag for the vmtp repository.
To build the image with tag "2.0.0" and "latest"::
$ cd <vmtp-ws-root>
$ sudo docker build --tag=$USER/vmtp:2.0.0 .
$ sudo docker build --tag=$USER/vmtp:latest .
$ sudo docker build --tag=berrypatch/vmtp:2.0.0 .
$ sudo docker build --tag=berrypatch/vmtp:latest .
The images should be available for use::
$ sudo docker images

Installation
============
===================================
Installation and Quick Start Guides
===================================
There are two ways to install and run VMTP tool. Users of VMTP should use regular PyPI based installation, while developers of VMTP should use GitHub/StackForge Repository based installation. Normally, PyPI based installation will satisfy most of use cases, and it is the recommended way for running VMTP under production environments, or through an automated or scheduled job. A git repository based installation gives more flexibility, and it is a must for developers of VMTP.
VMTP can be installed on any server that has access to the OpenStack API.
There are 3 ways to install and run the VMTP tool:
.. note:: Installation from PyPI will only have the latest stable version.
- Docker container
- PyPI package
- Git
The Git installation is required for VMTP developers and can be used for users who want to have access to the VMTP source code.
Otherwise, most users should select the Docker container installation (if already using Docker containers) or the more "pythonic" method with PyPI packages/pip.
PyPI based Installation
-----------------------
.. toctree::
:maxdepth: 2
PyPI (The Python Package Index) is the official repository for software in Python. It holds lots of packages, and the installation is relatively easy in only 2 steps.

Step 1
^^^^^^
Installation and Quick Start Guides:
Install required development libraries. Run the command based on your distro.

- :ref:`VMTP PyPI Installation and Quick Start Guide <pip_installation>`
- :ref:`VMTP Git Installation and Quick Start Guide <git_installation>`
Ubuntu/Debian based:
.. code-block:: bash
$ sudo apt-get install build-essential python-dev python-pip python-virtualenv git git-review
$ sudo apt-get install libxml2-dev libxslt-dev libffi-dev libz-dev libyaml-dev libssl-dev
RHEL/CentOS based:
.. code-block:: bash
$ sudo yum install gcc python-devel python-pip python-virtualenv git
$ sudo yum install libxml2-devel libxslt-devel libffi-devel libyaml-devel openssl-devel
MacOSX:
.. code-block:: bash
$ # Download the XCode command line tools from Apple App Store
$ xcode-select --install
$ sudo easy_install pip
$ sudo pip install virtualenv
Step 2
^^^^^^
Create a virtual environment for Python, and install VMTP:
.. code-block:: bash
$ virtualenv ./vmtpenv
$ source ./vmtpenv/bin/activate
$ pip install vmtp
$ vmtp -h
.. note::
"A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them." It is optional but recommended. We could use::
$ sudo pip install vmtp
instead if isolation among multiple Python projects is not needed.
.. _git_installation:
GitHub/OpenStack Repository based Installation

========================================================
VMTP Docker Container Installation and Quick Start Guide
========================================================
.. _docker_installation:
Using the VMTP Docker container is the simplest and fastest method if you are already using Docker.
1. Installation
---------------
VMTP is available as a container in Docker Hub at
`berrypatch/vmtp <https://hub.docker.com/r/berrypatch/vmtp/>`_
To pull the latest vmtp container image (you may not need to run these commands with "sudo" if you have root permission):
.. code-block:: bash
sudo docker pull berrypatch/vmtp
To test vmtp is working:
.. code-block:: bash
sudo docker run --rm berrypatch/vmtp vmtp -h
2. Key Pair
-----------
VMTP requires a key pair to use to ssh to the test VMs that it will launch in OpenStack.
You can use the current user's key pair (located in $HOME/.ssh on the host where you run the container) if they exist:
.. code-block:: bash
$ ls -l ~/.ssh/id*
-rw------- 1 localadmin localadmin 1679 Mar 9 2015 /home/localadmin/.ssh/id_rsa
-rw-r--r-- 1 localadmin localadmin 400 Mar 9 2015 /home/localadmin/.ssh/id_rsa.pub
Otherwise you need to create a key pair on your host:
.. code-block:: bash
ssh-keygen -t rsa
3. Download RC file
-------------------
VMTP requires downloading an "openrc" file from the OpenStack Dashboard (Project|Acces&Security!Api Access|Download OpenStack RC File). That RC file is required to connect to OpenStack using the OpenStack API.
This file should be passed to VMTP using the *-r* option or should be sourced prior to invoking VMTP.
Because VMTP runs in a Docker container, the RC file must be accessible from the container.
The simplest is to download the RC file on the Docker host and make the (host) directory directly accessible to the container using the -v option.
For example if the RC file is downloaded as "admin-openrc.sh" in the current directory, that file is accessible from the container by mapping the current host directory ($PWD) to the "/tmp/vmtp" directory in the container and using the "/tmp/vmtp/admin-openrc.sh" pathname (in the below example, the container command just lists the rc file before exiting)
.. code-block:: bash
sudo docker run --rm -v $PWD:/tmp/vmtp berrypatch/vmtp ls /tmp/vmtp/admin-openrc.sh
4. Preparation steps with OpenStack
-----------------------------------
Now that the RC file is available from the container, you can run any OpenStack CLI command in the container (since the container will have all standard OpenStack client packages installed along with VMTP). Run the container in interactive mode, get to its shell prompt and source the RC file:
.. code-block:: bash
sudo docker run --rm -it -v $PWD:/tmp/vmtp berrypatch/vmtp bash
root@af7cedc3866f:/# source /tmp/vmtp/admin-openrc.sh
4.1. Verify flavor names
^^^^^^^^^^^^^^^^^^^^^^^^
We will check the flavor names available as we will have to select one flavor that VMTP should use to launch VM instances.
List the flavors (results may be different):
.. code-block:: bash
root@af7cedc3866f:/# nova flavor-list
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| 1 | m1.tiny | 512 | 1 | 0 | | 1 | 1.0 | True |
| 2 | m1.small | 2048 | 20 | 0 | | 1 | 1.0 | True |
| 3 | m1.medium | 4096 | 40 | 0 | | 2 | 1.0 | True |
| 4 | m1.large | 8192 | 80 | 0 | | 4 | 1.0 | True |
| 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
root@af7cedc3866f:/# exit
exit
localadmin@GG27-16:~/wsvmtp$
4.2. Upload any Linux VM image to OpenStack
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
VMTP requires a standard Linux VM image to run its tests in OpenStack.
You can skip this step if you already have a standard Linux VM image in your OpenStack (Ubuntu, Fedora, RHEL...).
Otherwise, you can upload any Linux VM image using the glance CLI or using the Horizon dashboard.
In the example below we will upload the Ubuntu 14.04 cloud image available from the uec-images.ubuntu.com web site using the glance CLI and we will name it "Ubuntu Server 14.04".
If your OpenStack can access directly the Internet:
.. code-block:: bash
root@af7cedc3866f:/# glance --os-image-api-version 1 image-create --copy-from http://uec-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-uefi1.img --disk-format qcow2 --container-format bare --name 'Ubuntu Server 14.04'
The glance command will return immediately but it will take some time for the file to get transferred. You will need to check for the status of the image before you can use it (will "queued", then "saving" then "active" if there is no issue).
If you prefer to make a local copy of the image, from another terminal window on the host:
.. code-block:: bash
wget http://uec-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-uefi1.img
Then copy it to OpenStack using the glance CLI (from the container prompt):
.. code-block:: bash
root@af7cedc3866f:/# glance --os-image-api-version 1 image-create --file /tmp/vmtp/trusty-server-cloudimg-amd64-uefi1.img --disk-format qcow2 --container-format bare --name 'Ubuntu 14.04'
Then list the images to verify and exit the container:
.. code-block:: bash
root@af7cedc3866f:/# glance image-list
+--------------------------------------+---------------------+
| ID | Name |
+--------------------------------------+---------------------+

5. Create your VMTP config file
-------------------------------
Get a copy of the default VMTP configuration file and save it in the local directory:
.. code-block:: bash
sudo docker run --rm -v $PWD:/tmp/vmtp berrypatch/vmtp vmtp -s > vmtp.cfg
Edit the vmtp.cfg file and make sure the following parameters are set properly:
- "image_name" must be the image name to use by VMTP ('Ubuntu Server 14.04' in the above example)
- "ssh_vm_username" must be a valid user name for the Linux image ("ubuntu" for Ubuntu images)
- "flavor_type" must be an appropriate flavor name (step 4.1 above)
- "public_key_file" must point to your public key (see below)
- "private_key_file" must point to your private key (see below)
To access the key pairs from the container, the simplest is to map the $HOME/.ssh directory to /tmp/ssh in the container (for example):
.. code-block:: bash
sudo docker run --rm -v $HOME/.ssh:/tmp/ssh berrypatch/vmtp ls -l /tmp/ssh/id_rsa
With this mapping, the key pair parameters in the config file should be set to:
.. code-block:: bash
public_key_file: /tmp/ssh/id_rsa.pub
private_key_file: /tmp/ssh/id_rsa
6. Run VMTP
-----------
Docker options used:
* --rm : remove the container instance after execution
* -it : interactive mode + use a terminal
* -v $PWD:/tmp/vmtp : map the host current directory to /tmp/vmtp in the container
* -v $HOME/.ssh:/tmp/ssh : map the host $HOME/.ssh directory to /tmp/ssh in the container
VMTP options used:
* -d : debug mode (more verbose)
* -c /tmp/vmtp/vmtp.cfg : specify the config file to use
* -r /tmp/vmtp/admin-openrc.sh : specify the RC file to use
* -p secret : specify the OpenStack password to use (replace with your own password)
* --protocol T : only do TCP throughput test (shorter time)
* --json /tmp/vmtp/test.json : save results in json format to a file
.. code-block:: bash
sudo docker run --rm -it -v $PWD:/tmp/vmtp -v $HOME/.ssh:/tmp/ssh berrypatch/vmtp vmtp -d -c /tmp/vmtp/vmtp.cfg -r /tmp/vmtp/admin-openrc.sh -p secret --protocol T --json /tmp/vmtp/test.json
This should produce an output similar to this (a complete run with the above options should take around 15 minutes but may vary based on the control plane speed of your OpenStack cloud):
.. code-block:: bash

$ cd vmtp
$ python vmtp.py -h
Installation on RHEL/CentOS
^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: bash
$ sudo yum install gcc python-devel python-pip python-virtualenv git
$ sudo yum install libxml2-devel libxslt-devel libffi-devel libyaml-devel openssl-devel
$ sudo pip install git-review
$ # create a virtual environment
$ virtualenv ./vmtpenv
$ source ./vmtpenv/bin/activate
$ git clone git://git.openstack.org/openstack/vmtp
$ cd vmtp
$ pip install -r requirements-dev.txt
$ cd vmtp
$ python vmtp.py -h
Installation on MacOSX
^^^^^^^^^^^^^^^^^^^^^^
VMTP can run natively on MacOSX. These instructions have been verified to work on MacOSX 10.10 (Yosemite).
First, download XCode from App Store, then execute below commands:
.. code-block:: bash
$ # Download the XCode command line tools
$ xcode-select --install
$ # Install pip
$ sudo easy_install pip
$ # Install python virtualenv
$ sudo pip install virtualenv
$ # create a virtual environment
$ virtualenv ./vmtpenv
$ source ./vmtpenv/bin/activate
$ git clone git://git.openstack.org/openstack/vmtp
$ cd vmtp
$ pip install -r requirements-dev.txt
$ cd vmtp
$ python vmtp.py -h
2. Key Pair
-----------
VMTP requires a key pair to use to ssh to the test VMs that it will launch in OpenStack.
You can use the current user's key pair (located in $HOME/.ssh on the host where you run the container) if they exist:
.. code-block:: bash
$ ls -l ~/.ssh/id*
-rw------- 1 localadmin localadmin 1679 Mar 9 2015 /home/localadmin/.ssh/id_rsa
-rw-r--r-- 1 localadmin localadmin 400 Mar 9 2015 /home/localadmin/.ssh/id_rsa.pub
Otherwise you need to create a key pair on your host:
.. code-block:: bash
ssh-keygen -t rsa
3. Download RC file
-------------------
VMTP requires downloading an "openrc" file from the OpenStack Dashboard (Project|Acces&Security!Api Access|Download OpenStack RC File). That RC file is required to connect to OpenStack using the OpenStack API.
This file should be passed to VMTP using the *-r* option or should be sourced prior to invoking VMTP.
In this example we assume the RC file is saved in the current directory under the name "admin-openrc.sh".
4. Preparation steps with OpenStack
-----------------------------------
In the VMTP virtual environment, you can run any OpenStack CLI command (since the virtual environment will have all standard OpenStack client packages installed along with VMTP). Source the RC file so we can execute the CLI commands:
.. code-block:: bash
source admin-openrc.sh
4.1. Verify flavor names
^^^^^^^^^^^^^^^^^^^^^^^^
We will check the flavor names available as we will have to select one flavor that VMTP should use to launch VM instances.
List the flavors (results may be different):
.. code-block:: bash
$ nova flavor-list
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| 1 | m1.tiny | 512 | 1 | 0 | | 1 | 1.0 | True |
| 2 | m1.small | 2048 | 20 | 0 | | 1 | 1.0 | True |
| 3 | m1.medium | 4096 | 40 | 0 | | 2 | 1.0 | True |
| 4 | m1.large | 8192 | 80 | 0 | | 4 | 1.0 | True |
| 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
$
4.2. Upload any Linux VM image to OpenStack
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
VMTP requires a standard Linux VM image to run its tests in OpenStack.
You can skip this step if you already have a standard Linux VM image in your OpenStack (Ubuntu, Fedora, RHEL...).
Otherwise, you can upload any Linux VM image using the glance CLI or using the Horizon dashboard.
In the example below we will upload the Ubuntu 14.04 cloud image available from the uec-images.ubuntu.com web site using the glance CLI and we will name it "Ubuntu Server 14.04".
If your OpenStack can access directly the Internet:
.. code-block:: bash
glance --os-image-api-version 1 image-create --copy-from http://uec-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-uefi1.img --disk-format qcow2 --container-format bare --name 'Ubuntu Server 14.04'
The glance command will return immediately but it will take some time for the file to get transferred. You will need to check for the status of the image before you can use it (will "queued", then "saving" then "active" if there is no issue).
If you prefer to make a local copy of the image:
.. code-block:: bash
wget http://uec-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-uefi1.img
Then copy it to OpenStack using the glance CLI:
.. code-block:: bash
glance --os-image-api-version 1 image-create --file /tmp/vmtp/trusty-server-cloudimg-amd64-uefi1.img --disk-format qcow2 --container-format bare --name 'Ubuntu 14.04'
Then list the images to verify:
.. code-block:: bash
$ glance image-list
+--------------------------------------+---------------------+
| ID | Name |
+--------------------------------------+---------------------+
| 5d7899d9-811c-483f-82b3-282a9bf143bf | cirros |

5. Create your VMTP config file
-------------------------------
Get a copy of the default VMTP configuration file and save it in the local directory as "vmtp.cfg":
.. code-block:: bash
cp cfg.default.yaml vmtp.cfg
Edit the vmtp.cfg file and make sure the following parameters are set properly:
- "image_name" must be the image name to use by VMTP ('Ubuntu Server 14.04' in the above example)
- "ssh_vm_username" must be a valid user name for the Linux image ("ubuntu" for Ubuntu images)
- "flavor_type" must be an appropriate flavor name (step 4.1 above)
6. Run VMTP
-----------
VMTP options used:
* -d : debug mode (more verbose)
* -c vmtp.cfg : specify the config file to use
* -r admin-openrc.sh : specify the RC file to use
* -p secret : specify the OpenStack password to use (replace with your own password)
* --protocol T : only do TCP throughput test (shorter time)
* --json test.json : save results in json format to a file
.. code-block:: bash
python vmtp.py -d -c vmtp.cfg -r admin-openrc.sh -p secret --protocol T --json test.json
This should produce an output similar to this (a complete run with the above options should take around 15 minutes but may vary based on the control plane speed of your OpenStack cloud):
.. code-block:: bash

VMTP PyPI Installation and Quick Start Guide
============================================
.. _pip_installation:
1. Installation
---------------
PyPI (The Python Package Index) is the most popular distribution repository for software in Python.
The latest stable version of VMTP can be installed from PyPI using pip.
Step 1
^^^^^^
Install required libraries. Run the command based on your distro.
Ubuntu/Debian based:
.. code-block:: bash
$ sudo apt-get install build-essential python-dev python-pip python-virtualenv git git-review
$ sudo apt-get install libxml2-dev libxslt-dev libffi-dev libz-dev libyaml-dev libssl-dev
RHEL/CentOS based:
.. code-block:: bash
$ sudo yum install gcc python-devel python-pip python-virtualenv git
$ sudo yum install libxml2-devel libxslt-devel libffi-devel libyaml-devel openssl-devel
MacOSX:
.. code-block:: bash
$ # Download the XCode command line tools from Apple App Store
$ xcode-select --install
$ sudo easy_install pip
$ sudo pip install virtualenv
Step 2
^^^^^^
Create a virtual environment for Python, and install VMTP:
.. code-block:: bash
$ virtualenv ./vmtpenv
$ source ./vmtpenv/bin/activate
$ pip install vmtp
$ vmtp -h
.. note::
"A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them." It is optional but recommended. If isolation among multiple Python projects is not needed, we could use instead::
$ sudo pip install vmtp
2. Key Pair
-----------
VMTP requires a key pair to use to ssh to the test VMs that it will launch in OpenStack.
You can use the current user's key pair (located in $HOME/.ssh on the host where you run the container) if they exist:
.. code-block:: bash
$ ls -l ~/.ssh/id*
-rw------- 1 localadmin localadmin 1679 Mar 9 2015 /home/localadmin/.ssh/id_rsa
-rw-r--r-- 1 localadmin localadmin 400 Mar 9 2015 /home/localadmin/.ssh/id_rsa.pub
Otherwise you need to create a key pair on your host:
.. code-block:: bash
ssh-keygen -t rsa
3. Download RC file
-------------------
VMTP requires downloading an "openrc" file from the OpenStack Dashboard (Project|Acces&Security!Api Access|Download OpenStack RC File). That RC file is required to connect to OpenStack using the OpenStack API.
This file should be passed to VMTP using the *-r* option or should be sourced prior to invoking VMTP.
In this example we assume the RC file is saved in the current directory under the name "admin-openrc.sh".
4. Preparation steps with OpenStack
-----------------------------------
In the VMTP virtual environment, you can run any OpenStack CLI command (since the virtual environment will have all standard OpenStack client packages installed along with VMTP). Source the RC file so we can execute the CLI commands:
.. code-block:: bash
source admin-openrc.sh
4.1. Verify flavor names
^^^^^^^^^^^^^^^^^^^^^^^^
We will check the flavor names available as we will have to select one flavor that VMTP should use to launch VM instances.
List the flavors (results may be different):
.. code-block:: bash
$ nova flavor-list
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |

| 2 | m1.small | 2048 | 20 | 0 | | 1 | 1.0 | True |
| 3 | m1.medium | 4096 | 40 | 0 | | 2 | 1.0 | True |
| 4 | m1.large | 8192 | 80 | 0 | | 4 | 1.0 | True |
| 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+

4.2. Upload any Linux VM image to OpenStack
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
VMTP requires a standard Linux VM image to run its tests in OpenStack.
You can skip this step if you already have a standard Linux VM image in your OpenStack (Ubuntu, Fedora, RHEL...).
Otherwise, you can upload any Linux VM image using the glance CLI or using the Horizon dashboard.
In the example below we will upload the Ubuntu 14.04 cloud image available from the uec-images.ubuntu.com web site using the glance CLI and we will name it "Ubuntu Server 14.04".
If your OpenStack can access directly the Internet:
.. code-block:: bash
glance --os-image-api-version 1 image-create --copy-from http://uec-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-uefi1.img --disk-format qcow2 --container-format bare --name 'Ubuntu Server 14.04'
The glance command will return immediately but it will take some time for the file to get transferred. You will need to check for the status of the image before you can use it (will "queued", then "saving" then "active" if there is no issue).
If you prefer to make a local copy of the image:
.. code-block:: bash
wget http://uec-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-uefi1.img
Then copy it to OpenStack using the glance CLI:
.. code-block:: bash
glance --os-image-api-version 1 image-create --file /tmp/vmtp/trusty-server-cloudimg-amd64-uefi1.img --disk-format qcow2 --container-format bare --name 'Ubuntu 14.04'
Then list the images to verify:
.. code-block:: bash
$ glance image-list
+--------------------------------------+---------------------+

5. Create your VMTP config file
-------------------------------
Get a copy of the default VMTP configuration file and save it in the local directory:
.. code-block:: bash
vmtp -s > vmtp.cfg
Edit the vmtp.cfg file and make sure the following parameters are set properly:
- "image_name" must be the image name to use by VMTP ('Ubuntu Server 14.04' in the above example)
- "ssh_vm_username" must be a valid user name for the Linux image ("ubuntu" for Ubuntu images)
- "flavor_type" must be an appropriate flavor name (step 4.1 above)
6. Run VMTP
-----------
VMTP options used:
* -d : debug mode (more verbose)
* -c vmtp.cfg : specify the config file to use
* -r admin-openrc.sh : specify the RC file to use
* -p secret : specify the OpenStack password to use (replace with your own password)
* --protocol T : only do TCP throughput test (shorter time)
* --json test.json : save results in json format to a file
.. code-block:: bash
vmtp -d -c vmtp.cfg -r admin-openrc.sh -p secret --protocol T --json test.json
This should produce an output similar to this (a complete run with the above options should take around 15 minutes but may vary based on the control plane speed of your OpenStack cloud):

VNIC Type and SR-IOV Support

By default test VMs will be created with ports that have a "normal" VNIC type. To create test VMs with ports that use PCI passthrough SRIOV, specify **--vnic_type direct**. This will assume that the host where the VM are instantiated have SRIOV capable NIC.

Quick guide to run VMTP on an OpenStack Cloud
----------------------------------------------
Preparation
^^^^^^^^^^^
* Step 1)
Download the openrc file from OpenStack Dashboard, and saved it to your local file system. (In Horizon dashboard: Project|Acces&Security!Api Access|Download OpenStack RC File)
* Step 2)
Create one configuration file for your specific cloud and use the *-c* option to pass that file name to VMTP. Parameters that you are most certainly required to change are:
**image_name**: The name of the Linux image that will run the test VMs created by vmtp. It must be set to an existing image available in openstack (check the name with Horizon or using "nova image-list" from the shell). Any recent Ubuntu or CentOS/Fedora image should work -- if needed you will need to upload an image to OpenStack manually prior to running VMTP.
**ssh_vm_username**: VM SSH username to use (specific to the image)
**flavor_type**: The flavor name to use (often specific to each cloud)
* Step 3)
Upload the Linux image to the OpenStack controller node, so that OpenStack is able to spawning VMs. You will be prompted an error if the image defined in the config file is not available to use when running the tool. The image can be uploaded using either Horizon dashboard, or the command below::
python vmtp.py -r admin-openrc.sh -p admin --vm_image_url http://<url_to_the_image>
.. note:: Currently, VMTP only supports to load the image in qcow2 format.
