Using a virtual machine for development can work if you are not able to set up a development environment on your main machine for any reason.

Oracle VM VirtualBox (AKA VirtualBox) is a good option for the VM host virtualization software, as it is reliable, free, and open source.

== Installing VirtualBox ==

In your computer's firmware/BIOS/UEFI, make sure that all hardware virtualization technologies available for your computer are enabled: Intel VT-x, Intel VT-d, AMD AMD-V, AMD-Vi, other (EPT, RVI, VMCS shadowing, GVT, SR-IOV etc.). If it is available and you can enable it, then enable it.

* Arch/Manjaro: <code>sudo pacman -S virtualbox</code>
* Fedora: <code>sudo dnf install VirtualBox</code>
* KDE Neon/Kubuntu/Ubuntu/Debian: <code>sudo apt install virtualbox</code>
* openSUSE Leap & Tumbleweed: <code>sudo zypper install virtualbox</code>
* macOS: <code>brew install virtualbox</code>
* Windows: https://virtualbox.org/wiki/Downloads

Once VirtualBox is installed, launch it.

== Setting up the guest OS ==
Now it's time to install an operating system inside VirtualBox. For the purposes of this tutorial, we will use KDE Neon Developer Edition, as it is specifically made for this purpose. Download it from here: https://files.kde.org/neon/images/developer/current/neon-developer-current.iso

The OS inside VirtualBox is called the "guest OS" (as distinct from the "host OS" which is the OS running on your computer). It's time to set it up now.

Click the "New" button in the toolbar and go through the wizard, entering the following recommended settings:

[[File:4-_hard_disk_2.png|450px]]

[[File:5-_hard_disk_3.png|450px]]

Now click the "Start" button in the toolbar. This will prompt you to select an ISO file for the guest OS. Select the Neon Development ISO that you downloaded earlier:

Ensure you have increased the video memory, otherwise you will get a black screen (or just a cursor) when loading OS.

The OS will boot up! How exciting. Launch the installer and install the OS. When asked to create a user account, just pick any name (e.g. "dev").

After the OS has been installed, reboot the guest OS and then install some extra drivers and such from the "Guest Additions CD Image". Download and mount it like so:

Now press F4 to open the Terminal view and install by running the following command:
<pre>sudo ./VBoxLinuxAdditions.run</pre>

Now restart the guest OS again. Once it starts up, you're ready to [[Get Involved/development|do your development]] in a VM!
