VirtualBox is an open source cross-platform virtualization software, it can be installed on any operating system and enable you to install and run multiple guest operating systems on same computer.

For example, if you install it on your Linux system, you can run Windows XP operating system under it as a Guest OS or run Linux OS on your Windows system and so on. This way, you can install and run as many as guest operating systems as you like, the only limit is disk space and memory.

Recently Oracle has released latest stable version of Virtualbox 6.0.0, the newest version of Virtual box comes with so many major changes and new features added to it.

Whats new in Virtualbox 6.0

  • Added support for exporting a virtual machine to Oracle Cloud Infrastructure.
  • A much improved HiDPI and scaling support, along with superior detection and per-machine configuration.
  • A Major rework of user interface with smooth and easy setup of virtual machines.
  • A new file manager allows user to manage the guest file system and copy files between host and guest.
  • A major update of 3D graphics device emulation on Linux guests.
  • vboximg-mount utility for hosts enables users to access the content of guest disks on the host.
  • Added support for using Hyper-V on Windows host.

You can see the complete new change log details about VirtualBox 6.0 on their Official Changelog Page.

This guide explains how to install VirtualBox 6.0 on RHEL, CentOS and Fedora systems using VirtualBox’s own repository with YUM and DNF (for Fedora 22+ releases) tool.

This guide also explains how to install VirtualBox 6.0 on Debian, Ubuntu and Linux Mint systems using VirtualBox’s own repository with APT-GET or APT command.

Installing VirtualBox 6.0 in RHEL/CentOS and Fedora

If you’ve any earlier version of Virtualbox installed, remove that before installing latest version.

Adding VirtualBox Repository

Next add the VirtualBox own repository to install latest VirtualBox 6.0 on following systems.

For RHEL/CentOS 7/6/
For RHEL/CentOS 5
For Fedora 24-29

Install Dependency Packages for VirtualBox

VirtualBox uses vboxdrv kernel module to control and allocate physical memory for execution of guest operating systems. Without this module, you can still use the VirtualBox to create and configure virtual machines, but they will not work.

So, to make VirtualBox fully functional you will need to update your system first, then install some additional modules like DKMS, kernel-headers and kernel-devel and some dependency packages.

Install VirtualBox 6.0

Once you’ve installed all the needed dependency packages, you can install latest version of VirtualBox using following command.

Rebuild Kernel Modules for VirtualBox 6.0

The below command will automatically create vboxusers group and user and also search and automatically rebuild required kernel modules.

If the above build process fails, you will get a warning messages similar to below.

Then you need to first check your installed kernel and then install needed kernel-devel using following commands.

Note: replace CURRENT_KERNEL with string you get from uname -r.

Now run the build setup again.

Next, replace user_name in the following command with your own user name.

Troubleshooting

If you get any error message like KERN_DIR or if your kernel source directory not detected automatically by build process, you can set it by using following command. Make sure you change kernel version according to your system as shown in red color.

Thank you so much. I got this setup on Centos7. So far no problems.

Thanks Ravi, got it installed, per your instructions. Now it’s off to installing a Windows 7 virtual machine. (I may be back – soon)

Installing VirtualBox 6.0 in Debian, Ubuntu and Linux Mint does not work in Linux Mint 19. Can anyone tell me how to get VirtualBox 6.0 installed?

Have you followed instructions provided in the article for Linux Mint? If not, follow below instructions.

Install VirtualBox 6.0 on Linux Mint 19 and Linux Mint 18.

It worked perfect. Thank you!

I am also stuck on installing this. I have a centos7 and tried to install virtualbox. I started by downloading the virtualbox.repo and added it into my repositories.

But as soon as I type `yum update` I get a massive error:

[[email protected] yum.repos.d]# yum install VirtualBox-5.1

Can you maybe help me?

To fix, open and edit the file /etc/yum/pluginconf.d/rhnplugin.conf and change enabled to 0 and then do.

Please have a look at /var/log/vbox-install.log to trace why the build process failed

Run the following commands to build the kernel modules correctly : ( I am using RHEL -7)
