VirtualBox is a powerful tool for creating and managing virtual machines. If you want to serve your VMs from a server within your data center, and your preferable management tool is a GUI, what do you do? Once upon a time, you could use phpVirtualBox. Unfortunately, that tool hasn’t been in development for some time. However, there’s another option–RemoteBox. 

RemoteBox can be installed on Linux desktops, older releases of macOS (no newer than Catalina), and WSL on Windows 10. With this tool you can manage your VirtualBox VMs as if you were running the software on your desktop.

I’m going to show you how to get this system up and running on Ubuntu 20.04, both Server and Desktop.

What you’ll need

• Two instances of Ubuntu Linux–one Server and one Desktop 
• A user with sudo privileges

How to install the headless VirtualBox server 

The first thing to be done is the installation of VirtualBox on your server. Because we don’t have a GUI on the server, we’ll install a headless version.

Log in to your server and download the .deb file with the command:

wget https://download.virtualbox.org/virtualbox/6.1.16/virtualbox-6.1_6.1.16-140961~Ubuntu~eoan_amd64.deb

Install VirtualBox 6.1.16 with the command:

sudo dpkg -i *.deb

Add your user to the vboxusers group:

sudo usermod -aG vboxusers $USER

To make the system aware of the new group, log out of the server and log back in.

Now we must install the VirtualBox extension pack. Download the file with the command:

wget https://download.virtualbox.org/virtualbox/6.1.16/Oracle_VM_VirtualBox_Extension_Pack-6.1.16.vbox-extpack

Install the downloaded extension pack:

sudo vboxmanage extpack install Oracle_VM_VirtualBox_Extension_Pack-6.1.16.vbox-extpack

How to configure the VirtualBox server for remote connections

Next, we’ll configure remote connections to the headless VirtualBox server. Create a new configuration file with the command:

sudo nano /etc/default/virtualbox

In that file, add the following:

VBOXWEB_USER=user
VBOXWEB_PASSWD=password
VBOXWEB_TIMEOUT=0
VBOXWEB_HOST=server

Where:

• user is the username that belongs to the vboxusers group

• password is a password to be used (make it strong and unique)

• server is the IP address of the VirtualBox headless server

Save and close the file.

How to install RemoteBox

Download the RemoteBox file with the command:

wget http://remotebox.knobgoblin.org.uk/downloads/RemoteBox-2.7.tar.bz2

Uncompress the file with the command:

bunzip2 RemoteBox-2.7.tar.bz2

Unpack the tar file with the command:

tar xvf RemoteBox-2.7.tar

How to run RemoteBox and connect it to VirtualBox

With everything in place, we can start RemoteBox and connect it to our Headless VirtualBox server. Change into the RemoteBox folder with the command:

cd RemoteBox-2.7

Start RemoteBox with the command:

./remotebox

When the GUI opens, click Connect and fill out the necessary information for your VirtualBox headless server (Figure A).

Figure A

Use the credentials you configured in the /etc/default/virtualbox file for the login. 

Once you’re successfully connected, you can create a new virtual machine in the same way you do from the standard VirtualBox GUI tool.

Congratulations, you can now more easily manage your VirtualBox VMs remotely. Your data center (and those who administer the associated virtual machines within) will thank you for it.
