VirtualBox

Overview

Developed by Sun Microsystems, now Oracle Corporation, VirtualBox is a popular application that allows for other operating systems (known as Guests) to be installed and run within an existing operating system (known as the Host). This is undertaken through the process of virtualisation, whereby virtual versions of your computer (also referred to as virtual machines or VMs) are created within and draw resources directly from the host system. As such, how fast or powerful a virtual machine may be will depend entirely on the resources available - and allocated - for it to use. The benefits of virtualisation include:

The fast and easy installation of other operating systems without affecting your existing system (e.g. no need for dual booting and/or preparation in the form of hard disk partitioning or re-sizing)
Completely safe learning and experimentation with operating systems, as nothing that occurs within a Guest will affect the Host (e.g. the Host operating system can also be installed as a Guest in a virtual machine as a risk-free means of trying out new things), and
An almost unlimited capacity to install as many additional operating systems as desired...provided space is available on your hard drive to store them!

Installing Virtualbox on Manjaro

Enabling Virtualisation

Before installing VirtualBox, it is important to first ensure that virtualization has been enabled in your BIOS. The exact instructions for doing this vary based on your hardware. Please review the manual provided by your computer or motherboard manufacturer for specific instructions.

Install VirtualBox

To install VirtualBox, you need to install the packages virtualbox and linux*-virtualbox-host-modules. The latter must match the version of the kernel you are running. To list what kernels is installed use mhwd (example)

$ mhwd-kernel -li
Currently running: 5.4.0-1-MANJARO (linux54)
The following kernels are installed in your system:
   * linux54

To install VirtualBox and the kernel modules for your installed kernel enter the following command in the terminal:

$ sudo pacman -Syu virtualbox linux54-virtualbox-host-modules

Once the installation has completed, it will then be necessary to add the VirtualBox Module to your kernel. The easy way is to simply reboot your system. Otherwise, to start using VirtualBox immediately, enter the following command:

$ sudo vboxreload

Install the Extension Pack(Optional)

The extension pack is a proprietary set of extensions providing extra functionality to VirtualBox like USB2 and USB3 passthrough. You only need this if you are going to use the functionality provided and it is not required for VirtualBox to function.

Oracle Cloud Infrastructure integration
USB 2.0 and USB 3.0 Host Controller
Host Webcam
VirtualBox RDP
PXE ROM
Disk Encryption
NVMe

Info

As noted by VirtualBox - it is important you are using the extension pack matching your installed version of VirtualBox.
Please install the same version extension pack as your installed version of VirtualBox. – VirtualBox Download page

Check your VirtualBox version (example)

$ vboxmanage --version
6.1.14r140239

Install extensionpack using AUR

Locate the correct AUR PKGBUILD using pamac (or the AUR helper of choice) - example is using pamac

Info

AUR PKGBUILDs labelled manjaro is not maintained by Manjaro!

$ pamac search virtualbox-ext-oracle
virtualbox-ext-oracle-manjaro         6.1.12-2         AUR 
    Oracle VM VirtualBox Extension
    Pack
virtualbox-ext-oracle-beta            6.1.0_RC1-1      AUR 
    Oracle VM VirtualBox Extension
    Pack (Beta)
virtualbox-ext-oracle-5-test-build    5.2.35_135314-1  AUR 
    Oracle VM VirtualBox Extension
    Pack Test Build 5.2.35_135314
virtualbox-ext-oracle-5.0             5.0.40-1         AUR 
    Oracle VM VirtualBox Extension
    Pack
virtualbox-ext-oracle-5               5.2.x-1          AUR 
    Oracle VM VirtualBox Extension
    Pack 5.2.x (stable)
virtualbox-ext-oracle                 6.1.14-1         AUR 
    Oracle VM VirtualBox Extension
    Pack

When you have found the match you can install using the helper - example is using pamac

$ pamac build virtualbox-ext-<your-decision>

Get extensionpack from VirtualBox

Same rule apply - match your VirtualBox version - usually the latest version applies.

Downloads – Oracle VM VirtualBox

If the latest version do not match yours - you can find earlier versions using this page

Download Old Builds - Oracle VM Virtualbox

The extension .vbox-extpack is a registered mime extension so just open the file and VirtualBox will install the extension pack. Provide your password when asked.

Configuring the host

Adding Your Account to the vboxusers User Group

The final step is to now add your personal user account to the vboxusers group. This is necessary in order to fully access the features provided by VirtualBox. The $USER variable translates to the currently logged in user and you must logout or restart for the change to take effect.

$ sudo gpasswd -a $USER vboxusers

Manjaro VBox guest

For those intending to use Manjaro under VirtualBox, you can install Manjaro as usual. Please observe below point of setting the correct display type.

Selecting a Display Controller

Before installation of Manjaro ensure the correct display settings for VM. The Manjaro recommendation - to ensure the best experience - is contradicting the recommendations from VirtualBox developers. To have the VM screensize adapting to the window size - you need enable VBoxSVGA but doing so you cannot enable 3D. To use 3D you need to use VMSVGA which will force you to set the VM screen size inside the VM. If you use the VMSVGA adapter - mhwd will keep telling you to switch - you can do it but you will not be able to utilize 3D graphics.

Troubleshooting guest

If you deem it necessary to ensure the packages are installed please follow this recipe

$ mhwd-kernel -li                                                           
Currently running: 5.4.0-1-MANJARO (linux54)
The following kernels are installed in your system:
   * linux54
$ sudo pacman -Syu virtualbox-guest-utils linux54-virtualbox-guest-modules

Guest Configuration

You will need to load the modules if you don't want to reboot:

$ sudo modprobe vboxguest vboxvideo vboxsf

The guest utils than need to be started and enabled:

$ sudo systemctl enable --now vboxservice.service

Add you VM user to the vboxsf group (this requires you to logout to apply the new group)

$ sudo usermod -aG vboxsf ${USER}

Create media folder in root directory if it does not already exist

$ sudo mkdir /media

Assign the correct permissions to the media folder to be able to access shared folders

$ sudo chmod 755 /media

Советы, подсказки и рекомендации

Advice on using Virtualbox effectively, as well as some tips and tricks learned along the way, have been provided for the benefit of new users.

Guest Installation

Virtualbox can run installation files (ISOs) directly as virtual discs, so there is no need to burn them to an installation medium such as a disc or USB data stick.
The process to install any Guest operating system, including Manjaro, is exactly the same as if actually installing for real on your computer.

Guest Additions

Guest Additions are special software packages designed to improve the performance and usability of guest operating systems.

They are installed within the Guest operating system itself, and most notably result in enhancing the display resolution, as well as enabling much better control over the mouse. As such, two tell-tale signs that Guest Additions have not been installed in a Guest are that the display will not scale to the size of the display window (i.e. it will be necessary to scroll around to see the whole screen), and the mouse may be quite hard to control.

Instructions for installing the guest additions in Manjaro are provided above. For other operating systems please review the VirtualBox instructions linked below

Guest Display

If you are using other guests e.g. Ubuntu, Linux Mint and others be sure to use the default VMSVGA display driver.

It will be necessary to activate the Enable 3D acceleration box in order to allow for some desktop effects (such as transparency) to be shown. This can be undertaken by going into the settings menu, and then selecting the Display section.

If you are getting screen distortion or transparent dialogs using Windows guest - shutdown the VM and change the graphics settings of the VM. Remove the checkbox for Enable 3D acceleration.

Guest Internet Connection

Some users have encountered problems when attempting to connect their virtual machine to the internet using the default VirtualBox settings. Where this is the case, try the following solution

Click the Settings Button and then select the Network tab
Next to the Attached to heading is a button that states NAT. Click it to reveal a drop down menu and select Bridged Adapter instead.
Next to the Name heading is a button whereby you may select how you are currently connected to the internet (e.g. Wlan means Wireless, and Eth0 means Ethernet). Select the appropriate connection type you are currently using.
Click the OK button to confirm.

General Troubleshooting

A VirtualBox installation will not automatically detect when USB device has been connected. As such, it is therefore necessary to click the USB icon located at the bottom of the VirtualBox window in order to select and activate it.
It is possible to enable the (very useful) ability to copy and paste text between the Guest and Host systems. This is undertaken by clicking Settings button and then going to the General Section.
Don't be afraid to take risks, to experiment, and to have fun with Guest operating systems. The worst that can happen is that they will have to be re-installed!
