When the update the complete, reboot your CentOS 8 system. Once prompted, press 'Y' and hit ENTER to continue with the update. To resolve the issue, update the Linux kernel by running the command: $ sudo dnf update kernel-* The output clearly indicates a conflict between the two versions. Once installed, confirm that the version of kernel-devel corresponds to the version of your Linux kernel by running these commands: $ rpm -q kernel-devel $ sudo dnf install gcc make perl kernel-devel kernel-headers bzip2 dkms With the EPEL repository installed, proceed and install the kernel headers and build tools required to install the guest additions as shown. $ rpm -q epel-releaseĬonfirm EPEL Repository Step 2: Installing Kernel Headers and Build Tools Once installed, confirm the version installed by running the command. To install the EPEL repository on CentOS 8, run the following dnf command on the terminal.

To start off, begin by installing the EPEL repository, in short for Extra Packages for Enterprise Linux, which is a repository that provides extra open-source software packages for RedHat flavors such as CentOS and Fedora. In this guide, we will walk you through the installation of VirtualBox guest additions on CentOS 8. VirtualBox guest additions can be installed on both Linux and Windows systems.
Improved the graphical display/appearance.The VirtualBox guest additions enable the functionalities listed below: The image is then mounted onto the guest system and the guest additions are thereafter installed.

To improve the appearance and functionality of a virtual machine, VirtualBox provides a set of software packages and drivers known as VirtualBox guest additions in the form of an ISO image known as VBoxGuestAdditions.iso. You can verify this by looking at the running kernel with uname -aĪnd the installed sources at ls /usr/src/kernelsĪs a final conclusion, whatever happens, look at the messages and log files provided.When you first install a virtual machine with a GUI on VirtualBox, the screen size is usually scaled-down and the user experience is usually quite bland. So, running kernel and installed kernel sources (aka kernel-devel) must match. After installing the proper kernel-devel package, building and then installing worked as expected. Now it complained about missing header files and suggested to do yum install kernel-devel-2.6.86_64Īs you can see, this is a slightly different version, 504.16.2 vs just 504. Since kernel-devel and sources at /usr/src/kernels/2.6.32-504.16.2.el6.x86_64 were already installed, I was confused, but called it with the requested environment variable KERN_DIR=/usr/src/kernels/2.6.32-504.16.2.el6.x86_64 sh /media/cdrom/n There it said something about missing kernel sources and to provide the kernel source directory with e.g. In my case, one of them asked to look into /var/log/vboxadd-install.log. If it doesn't work for you, look at the messages. Answer almost worked, but it failed building some kernel modules.
