VirtualBox 2021 Review for linux Ubuntu



VirtualBox is a cross-platform virtualization software application developed by Oracle Corporation. If you love trying out new operating systems then VirtualBox is the must have Ubuntu application for you. You can tryout Linux, Mac inside Windows Operating System or Windows and Mac inside Linux.

How to Installing on Linux Hosts

For the various versions of Linux that are supported as host operating systems, see Section 1.4, “Supported Host Operating Systems”.

You may need to install the following packages on your Linux system before starting the installation. Some systems will do this for you automatically when you install Oracle VM VirtualBox.

The Oracle VM VirtualBox Kernel Modules

In order to run other operating systems in virtual machines alongside your main operating system, Oracle VM VirtualBox needs to integrate very tightly with your system. To do this it installs a driver module called vboxdrv into the system kernel. The kernel is the part of the operating system which controls your processor and physical hardware. Without this kernel module, you can still use the VirtualBox Manager to configure virtual machines, but they will not start.

Network drivers called vboxnetflt and vboxnetadp are also installed. They enable virtual machines to make more use of your computer's network capabilities and are needed for any virtual machine networking beyond the basic NAT mode.

Since distributing driver modules separately from the kernel is not something which Linux supports well, the Oracle VM VirtualBox install process creates the modules on the system where they will be used. This means that you may need to install some software packages from the distribution which are needed for the build process. Required packages may include the following:

Installing on Linux Hosts

Welcome to our Virtualization guide on how to install VirtualBox 6.1 on Kali Linux / Linux Mint 19. VirtualBox is an open source, high-performance Virtualization solution being developed by Oracle Corporation. It is a commonly used tool among Developers and System Administrators.

VirtualBox 6.1 New Features

  • Implemented support for exporting a virtual machine to Oracle Cloud Infrastructure
  • User interface: greatly improved HiDPI and scaling support, including better detection and per-machine configuration
  • Major rework of user interface with simpler and more powerful application and virtual machine set-up
  • User interface: a new file manager enabling user to control the guest file system and copy files between host and guest.
  • Graphics: major update of 3D graphics support for Windows guests, and VMSVGA 3D graphics device emulation on Linux and Solaris guests
  • Added support for surround speaker setups (as used by Windows 10 Build 1809)
  • Added utility vboximg-mount on Apple hosts to access the content of guest disks on the host
  • Added support for using Hyper-V as the fallback execution core on Windows host, to avoid the inability to run VMs at the price of reduced performance

Step 1: Update your system

sudo apt update
sudo apt -y upgrade
sudo reboot

Step 2: Import apt repository

wget -q -O- | sudo apt-key add -

wget -q -O- | sudo apt-key add -

 Step 3:  Add the VirtualBox Repository

Kali Linux:

echo "deb [arch=amd64] buster contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list

Linux Mint 19:

echo "deb [arch=amd64] bionic contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list

Step 4:  Install VirtualBox & Extension pack

sudo apt update && sudo apt upgrade
sudo reboot
sudo apt install linux-headers-$(uname -r) dkms
sudo apt-get install virtualbox-6.1

Download VirtualBox Extension Pack

cd ~/

Once the file is downloaded, install the extension pack by clicking on the Downloaded file

Click install and wait for the installation to complete.

Step 5: Launching VirtualBox 6.1

$ virtualbox

The new user interface for VirtualBox 6.1 looks like below:
