CentOS/RHEL: installing VirtualBox 6.1

VirtualBox is open source virtualisation software developed and published by Oracle. Since Oracle VM VirtualBox 5.2, it requires SSE2 CPU extensions. This setup uses the vboxdrv, vboxnetflt and vboxnetadp kernel modules.

Add the VirtualBox repository

$ sudo dnf -y install wget
$ wget https://download.virtualbox.org/virtualbox/rpm/el/virtualbox.repo
$ sudo mv virtualbox.repo /etc/yum.repos.d/

Import the Oracle repository signing key

wget -q https://www.virtualbox.org/download/oracle_vbox.asc
sudo rpm --import oracle_vbox.asc

Install additional packages

This step requires EPEL:

sudo dnf -y install binutils kernel-devel kernel-headers libgomp make patch gcc glibc-headers glibc-devel dkms

Install VirtualBox

sudo dnf install -y VirtualBox-6.1

Final configuration

sudo usermod -aG vboxusers $USER
sudo /usr/lib/virtualbox/vboxdrv.sh setup
