If the versions of the two ( kernel version and kernel-devel) do not match as shown in the screenshot above, update the kernel using the command. To check the version of the kernel development tool ( kernel-devel) execute. To check the version of the Linux kernel run the command. Once you have successfully installed kernel headers, you need to confirm the version of the Linux kernel and ensure it matches the version of the just installed kernel headers. $ sudo dnf install dkms kernel-devel gcc bzip2 make curl This includes the installation of the dkms package ( Dynamic Kernel Module Support) alongside other build tools as shown. The first step in the installation of VirtualBox guest additions is the installation of kernel headers. Step 1: Install Kernel Headers and Build Tools To install and enable VirtualBox guest additions on your Fedora Linux, you must have VirtualBox installed on your system, if not install it using our guide: How to Install VirtualBox in Fedora Linux. Installing VirtualBox Guest Additions in Fedora Let’s now see how you can install VirtualBox guest additions on Fedora Linux distribution. For example, if the host’s resolution is 1366 x 768, the virtual machine automatically scales from its default resolution to match the host’s resolution. With guest addition installed, the virtual machine adjusts to match the resolution of the host system. Enhanced Video Performance: By default, virtual machines come with a display that is much smaller and does not provide a resolution that matches that of the host system.

Shared Folders: The guest additions also enable you to make folders that can be accessed by the virtual machine as network shares.Mouse Pointer Integration: Recall how you usually have to press a combination of keys to release the mouse pointer from the virtual machine? With Virtualbox guest additions, that becomes a thing of the past as you can comfortably move your mouse pointer to and from the guest and host OS.Drag and Drop: Additionally, Virtualbox guest additions enable you to drag and drop files between the host and guest operating systems.

Shared Clipboard: You can seamlessly copy and paste content between the host and guest operating systems.

VirtualBox guest additions provide extended features such as: VirtualBox also includes VirtualBox guest additions which are additional applications and drivers that improve the performance and usability of a virtual machine. As you might know, VirtualBox is an open-source hypervisor that allows users to create virtual machines and test-run different operating systems.
