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 guests operating systems on the 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 the latest stable version of Virtualbox 6.1, the newest version of Virtual box comes with so many major changes and new features added to it.

You can see the complete new changelog details about VirtualBox 6.1 on their Official Changelog Page.

This guide explains how to install VirtualBox 6.1 on RHEL, CentOS, and Fedora systems using VirtualBox’s own repository with YUM and DNF tools.

This guide also explains how to install VirtualBox 6.1 on Debian, Ubuntu and Linux Mint systems using VirtualBox’s own repository with APT-GET or APT command.

Installing VirtualBox 6.1 in RHEL/CentOS and Fedora

To install the latest stable version of VirtualBox, you need to first download the virtualbox.repo configuration file using the following wget command and then import the public key using rpm command.

----------------- On CentOS and RHEL ----------------- # wget https://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo -P /etc/yum.repos.d/ # rpm --import https://www.virtualbox.org/download/oracle_vbox.asc ----------------- On Fedora ----------------- # wget http://download.virtualbox.org/virtualbox/rpm/fedora/virtualbox.repo -P /etc/yum.repos.d/ # rpm --import https://www.virtualbox.org/download/oracle_vbox.asc

Next, enable the EPEL repository to install build tools and dependencies on the system.

----------------- On CentOS/RHEL 8 ----------------- # dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm ----------------- On CentOS/RHEL 7 ----------------- # yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ----------------- On CentOS/RHEL 6 ----------------- # yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

Install Dependency Packages for VirtualBox

VirtualBox uses vboxdrv kernel module to control and allocate physical memory for the 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.

----------------- On CentOS/RHEL 8 ----------------- # dnf update # dnf install binutils kernel-devel kernel-headers libgomp make patch gcc glibc-headers glibc-devel dkms -y ----------------- On CentOS/RHEL 7/6 ----------------- # yum update # yum install binutils kernel-devel kernel-headers libgomp make patch gcc glibc-headers glibc-devel dkms -y ----------------- On Fedora ----------------- # dnf update # dnf install @development-tools # dnf install kernel-devel kernel-headers dkms qt5-qtx11extras elfutils-libelf-devel zlib-devel

Install VirtualBox 6.1

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

# dnf install VirtualBox-6.1 OR # yum install VirtualBox-6.1

At this point, you are ready to start using VirtualBox by running the following command on the terminal.

# virtualbox

If you get the following error during the Virtualbox installation, it means there is a conflict between the two Kernel versions.

This system is currently not set up to build kernel modules. Please install the Linux kernel "header" files matching the current kernel

To resolve the issue, first, check your installed kernel and then update the Linux kernel by running the command:

# uname -r # dnf update kernel-* Or # yum update kernel-*

When the update complete, reboot your system and select the latest kernel from the grub boot menu, this entry usually the first entry as you can see.

# reboot

Once the system is done with booting, log in and once again confirm that the kernel-devel version now matches the version of the Linux kernel.

# rpm -q kernel-devel # uname -r

Then, re-start the build set-up process and confirm that your VirtualBox installation was successful by running:

# /sbin/vboxconfig # systemctl status vboxdrv

Troubleshooting

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

## RHEL / CentOS / Fedora ## KERN_DIR=/usr/src/kernels/4.19.0-1.el7.elrepo.x86_64 ## Export KERN_DIR ## export KERN_DIR

Installing VirtualBox 6.1 in Debian, Ubuntu and Linux Mint
