Instructions

Install required packages] for a guest addition compilation

# dnf install tar bzip2 kernel-devel-$(uname -r) kernel-headers perl gcc make elfutils-libelf-devel

Insert Virtualbox guest additions ISO image

NOTE
Use the latest Virtualbox Guest addition CD image if possible. The ISO supplied with your VirtualBox may be outdated which might result in compilation errors.

Use the following link to download the latest Virtualbox Guest addition ISO image.

"Click on the Devices menu and select Insert Guest Additions CD image..."

Click on the Devices menu and select Insert Guest Additions CD image...

Compile and install Virtualbox guest additions. Once you insert the Virtualbox Guest addition ISO image the window may pop-up. You can hit the Run button to begin the installation.

"Begin the Virtualbox guest additions installation"

Begin the Virtualbox guest additions installation

However, I suggest to start the installation from the command line in order to get more verbose output from the installation process. This way it is easier to troubleshoot any possible issues you encounter.

"Mounted Virtualbox guest additions ISO location"

Mounted Virtualbox guest additions ISO location.

To do so run the following command:

$ cd /run/media/`whoami`/VB*

Change to the root user and begin installation:

$ su
# ./VBoxLinuxAdditions.run

if successful you should see the following output:

Installing additional modules ...
VirtualBox Guest Additions: Building the VirtualBox Guest Additions kernel modules.  This may take a while.
VirtualBox Guest Additions: Running kernel modules will not be replaced until the system is restarted
VirtualBox Guest Additions: Starting.

Reboot your system to enable the Virtualbox guest additions.

Confirm that Virtualbox guest additions are installed and loaded

# lsmod | grep vbox
