Install VirtualBox on RHEL, CentOS, AlmaLinux, Rocky Linux or Oracle Linux

This how-to is about installing VirtualBox on Red Hat Enterprise Linux (RHEL). Provided instructions should also work on CentOS, AlmaLinux, Rocky Linux or Oracle Linux.

It is possible to install VirtualBox from rpm packages, which can be downloaded on the VirtualBox Linux downloads page. However, a yum-style repository is also provided – we’ll use the latter.

Install DKMS, use sudo

Before installing VirtualBox, one should install DKMS, as VirtualBox will build its own kernel module. This howto also supposes that you have added yourself to the sudoers list (of course, you may as well use su or log in as root).

DKMS has some important dependencies like gcc and kernel-devel. Use the following command line to install DKMS and its dependancies:
sudo yum install dkms

Install Virtualbox

Once DKMS an its dependencies are installed, we can download and add the repo file to /etc/yum.repos.d/:
sudo wget -P /etc/yum.repos.d http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

Finally, VirtualBox is ready to install:
sudo yum install VirtualBox-6.1

Add yourself to the vboxusers group using the “Users and Groups” application or the command line:
sudo usermod -a -G vboxusers your_user_name

It is possible to use VirtualBox without adding yourself (as a user) to the vboxusers group. If you don’t, some functions may be unavailable, as using USB devices on the guest system.

Run Virtualbox

VirtualBox should now be available in the menu or running VirtualBox. Don’t forget to install the non-free Extension Pack via the “File → Preferences → Extensions” menu.
