###############
Running on GNS3
###############
Sometimes you may want to test VyOS in a lab environment.
`GNS3 <http://www.gns3.com>`__ is a network emulation software you
might use for it.
This guide will provide the necessary steps for installing
and setting up VyOS on GNS3.
Requirements
------------
The following items are required:
* A VyOS installation image (.iso file). You
can find how to get it on the :ref:`installation` page
* A working GNS3 installation. For further information see the
`GNS3 documentation <https://docs.gns3.com/>`__.
.. _vm_setup:
VM setup
--------
First, a virtual machine (VM) for the VyOS installation must be created
in GNS3.
Go to the GNS3 **File** menu, click **New template** and choose select
**Manually create a new Template**.
.. figure:: /_static/images/gns3-01.png
Select **Quemu VMs** and then click on the ``New`` button.
.. figure:: /_static/images/gns3-02.png
Write a name for your VM, for instance "VyOS", and click ``Next``.
.. figure:: /_static/images/gns3-03.png
Select **qemu-system-x86_64** as Quemu binary, then **512MB** of RAM
and click ``Next``.
.. figure:: /_static/images/gns3-04.png
Select **telnet** as your console type and click ``Next``.
.. figure:: /_static/images/gns3-05.png
Select **New image** for the base disk image of your VM and click
``Create``.
.. figure:: /_static/images/gns3-06.png
Use the defaults in the **Binary and format** window and click
``Next``.
.. figure:: /_static/images/gns3-07.png
Use the defaults in the **Qcow2 options** window and click ``Next``.
.. figure:: /_static/images/gns3-08.png
Set the disk size to 2000 MiB, and click ``Finish`` to end the **Quemu
image creator**.
.. figure:: /_static/images/gns3-09.png
Click ``Finish`` to end the **New QEMU VM template** wizard.
.. figure:: /_static/images/gns3-10.png
Now the VM settings have to be edited.
Being again at the **Preferences** window, having **Qemu VMs**
selected and having our new VM selected, click the ``Edit`` button.
.. figure:: /_static/images/gns3-11.png
In the **General settings** tab of your **QEMU VM template
configuration**, do the following:
* Click on the ``Browse...`` button to choose the **Symbol** you want to
have representing your VM.
* In **Category** select in which group you want to find your VM.
* Set the **Boot priority** to **CD/DVD-ROM**.
.. figure:: /_static/images/gns3-12.png
At the **HDD** tab, change the Disk interface to **sata** to speed up
the boot process.
.. figure:: /_static/images/gns3-13.png
At the **CD/DVD** tab click on ``Browse...`` and locate the VyOS image
you want to install.
.. figure:: /_static/images/gns3-14.png
.. note:: You probably will want to accept to copy the .iso file to your
default image directory when you are asked.
In the **Network** tab, set **0** as the number of adapters, set the
**Name format** to **eth{0}** and the **Type** to **Paravirtualized
Network I/O (virtio-net-pci)**.
.. figure:: /_static/images/gns3-15.png
In the **Advanced** tab, unmark the checkbox **Use as a linked base
VM** and click ``OK``, which will save and close the **QEMU VM template
configuration** window.
.. figure:: /_static/images/gns3-16.png
At the general **Preferences** window, click ``OK`` to save and close.

.. _vyos_installation:
VyOS installation
-----------------
* Create a new project.
* Drag the newly created VyOS VM into it.
* Start the VM.
* Open a console.
The console should show the system booting. It will ask for the login
credentials, you are at the VyOS live system.
* :ref:`Install VyOS <installation>`
as normal (that is, using the ``install image`` command).
* After a successful installation, shutdown the VM with the ``poweroff``
command.
* **Delete the VM** from the GNS3 project.
The *VyOS-hda.qcow2* file now contains a working VyOS image and can be
used as a template. But it still needs some fixes before we can deploy
VyOS in our labs.
.. _vyos_vm_configuration:
VyOS VM configuration
---------------------
To turn the template into a working VyOS machine, further steps are
necessary as outlined below:
**General settings** tab: Set the boot priority to **HDD**
.. figure:: /_static/images/gns3-20.png
**CD/DVD** tab: Unmount the installation image file by clearing the
**Image** entry field.
.. figure:: /_static/images/gns3-21.png
Set the number of required network adapters, for example **4**.
.. figure:: /_static/images/gns3-215.png
**Advanced** settings tab: Mark the checkbox **Use as a linked
base VM** and click ``OK`` to save the changes.
.. figure:: /_static/images/gns3-22.png
The VyOS VM is now ready to be deployed.
