Install VirtualBox on CentOS 8 & also on RHEL 8 Linux. Here, We will see how to install VirtualBox on CentOS 8 / RHEL 8. Oracle VirtualBox requires an existing OS to be installed and thus run alongside existing applications on that host. The installation should be straightforward on any Linux system with Linux kernel 2.6 or 3.x.
Starting with Oracle VirtualBox, the SSE2 CPU extension is required. The installer with automatically builds and installs the Oracle VirtualBox kernel modules: vboxdrv, vboxnetflt, and vboxnetadp.
Step 1: Adding VirtualBox / EPEL repository
Add the VirtualBox repository to the local system by downloading virtualbox.repo file and placing it under /etc/yum.repos.d directory.
sudo dnf -y install wget
wget https://download.virtualbox.org/virtualbox/rpm/el/virtualbox.repo
sudo mv virtualbox.repo /etc/yum.repos.d/
Import Oracle public key:
wget -q https://www.virtualbox.org/download/oracle_vbox.asc
sudo rpm --import oracle_vbox.asc
We also need to add EPEL repository:
sudo dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
Step 2: Install VirtualBox
Download required build tools for VirtualBox.
sudo dnf -y install binutils kernel-devel kernel-headers libgomp make patch gcc glibc-headers glibc-devel dkms
Now install the latest version of VirtualBox 6.1 by running the command:
sudo dnf install -y VirtualBox-6.1
The installation command will build kernel modules and automatically create vboxusers group. Any system user who is going to use USB devices from Oracle VM VirtualBox guests must be a member of that group.
To manually add VirtualBox user must to be a member of the group.
sudo usermod -aG vboxusers $USER
To rebuild Kernel modules, run:
sudo /usr/lib/virtualbox/vboxdrv.sh setup
Step 3: Starting VirtualBox
You have the flexibility of starting Oracle VM VirtualBox program by running the program of your choice (VirtualBox, VBoxManage, or VBoxHeadless) from a terminal.
$ VirtualBox
Alternatively start VirtualBox 6.1 on RHEL 8 / CentOS 8 from GUI by navigating to Application >> System Tools >> Oracle VM VirtualBox.
