<p>This page describes how to configure a VM for running ETSI TeraFlowSDN(TFS) controller using <a href="https://www.virtualbox.org/">Oracle VirtualBox</a>. It has been tested with VirtualBox up to version 6.1.40 r154048.</p>
<h1 id="create-a-nat-network-in-virtualbox">Create a NAT Network in VirtualBox</h1>
<p>In "Oracle VM VirtualBox Manager", Menu "File &gt; Preferences... &gt; Network", create a NAT 
network with the following specifications:</p>
<table>

<tr>

<th>CIDR</th>
<th>DHCP</th>
<th>IPv6</th>
</tr>
</thead>
<tbody>
<tr>
<td>TFS-NAT-Net</td>
<td>10.0.2.0/24</td>
<td>Disabled</td>
<td>Disabled</td>
</tr>
</tbody>
</table>
<p>Within the newly created "TFS-NAT-Net" NAT network, configure the following IPv4 
forwarding rules:</p>
<table>
<thead>
<tr>
<th>Name</th>
<th>Protocol</th>
<th>Host IP</th>
<th>Host Port</th>
<th>Guest IP</th>
<th>Guest Port</th>

<p>In "Oracle VM VirtualBox Manager", start the VM in normal mode, and follow the 
installation procedure.
Below we provide some installation guidelines:
- Installation Language: English
- Autodetect your keyboard
- If asked, select "Ubuntu Server" (do not select "Ubuntu Server (minimized)").
- Configure static network specifications:</p>

<ul>
<li>Leave proxy and mirror addresses as they are</li>
<li>Let the installer self-upgrade (if asked).</li>
<li>Use an entire disk for the installation</li>
<li>Disable setup of the disk as LVM group</li>
<li>Double check that NO swap space is allocated in the partition table. Kubernetes does not work properly with SWAP.</li>
<li>Configure your user and system names:</li>
<li>User name: TeraFlowSDN</li>
<li>Server's name: tfs-vm</li>
<li>Username: tfs</li>
<li>Password: tfs123</li>
<li>Install Open SSH Server</li>
<li>Import SSH keys, if any.</li>
<li>Featured Server Snaps</li>
<li>Do not install featured server snaps. It will be done manually later to illustrate how to uninstall and reinstall them in case of trouble with.</li>
<li>Let the system install and upgrade the packages.</li>
<li>This operation might take some minutes depending on how old is the Optical Drive ISO image you use and your Internet connection speed.</li>
<li>Restart the VM when the installation is completed.</li>
</ul>
<h2 id="upgrade-the-ubuntu-distribution">Upgrade the Ubuntu distribution</h2>
<pre><code class="language-bash">sudo apt-get update -y
sudo apt-get dist-upgrade -y

<li>If asked to restart services, restart the default ones proposed.</li>
<li>Restart the VM when the installation is completed.</li>
</ul>
<h2 id="install-virtualbox-guest-additions">Install VirtualBox Guest Additions</h2>
<p>On VirtualBox Manager, open the VM main screen. If you are running the VM in headless 
mode, right click over the VM in the VirtualBox Manager window and click "Show".
If a dialog informing about how to leave the interface of the VM is shown, confirm 
pressing "Switch" button. The interface of the VM should appear.</p>
<p>Click menu "Device &gt; Insert Guest Additions CD image..."</p>
<p>On the VM terminal, type:</p>
<pre><code class="language-bash">sudo apt-get install -y linux-headers-$(uname -r) build-essential dkms
  # This command might take some minutes depending on your VM specs and your Internet access speed.
sudo mount /dev/cdrom /mnt/
cd /mnt/
sudo ./VBoxLinuxAdditions.run
  # This command might take some minutes depending on your VM specs.
sudo reboot
