Steps to Install VirtualBox Guest Additions on Fedora:

1. Update the System

• Open a terminal in your Fedora guest and ensure your system is up to date:

sudo dnf update

2. Install Required Packages

• Install the necessary packages for building kernel modules:

sudo dnf install gcc kernel-devel kernel-headers dkms make bzip2 perl

3. Insert the Guest Additions CD

• In the VirtualBox window for your Fedora guest, go to the Devices menu and select Insert Guest Additions CD Image.
• If prompted to download the Guest Additions image, confirm and let it download.

4. Mount the CD Image

• If the CD image does not automatically mount, manually mount it:

sudo mount /dev/cdrom /mnt

5. Run the Installer

• Navigate to the mounted directory and run the Guest Additions installer:

cd /mnt 
sudo ./VBoxLinuxAdditions.run

6. Reboot the System

• After the installation is complete, reboot your Fedora guest system:

sudo reboot

7. Verify Installation

• After rebooting, verify that the Guest Additions are working. Features like shared folders, clipboard sharing, and improved display resolution should now be available.

Troubleshooting:

• If you encounter any issues, ensure that your kernel is up to date and matches the version of kernel-devel.
• Reinstall the kernel-devel package if there are mismatches:

sudo dnf reinstall kernel-devel

This process will enable features like better screen resolution, shared clipboard, and shared folders in your Fedora VirtualBox guest.
