Fedora 25 has been released recently and most people want to try this new Fedora 25 on their computer via Virtualbox. Unfortunately, Fedora 25 does not shipped with Guest Additions installed, so you won’t get full screen features on your Virtualbox with this Fedora 25 Workstation. And here I want to show you how to fix it by installing Virtualbox Guest Additions on Fedora 25.
If you are willing to run Fedora 25 on Virtualbox as Guest Machine, I suggest you to allocate 5 GB of RAM to Fedora 25 guest machine. It will run faster and smoother.
Please follow these guide to install Virtualbox Guest Additions on Fedora 25
Step 1. Update Kernel
Execute this command to update your kernel.
sudo dnf update kernel*
Step 2. Reboot Fedora
Step 3. Install required packages
sudo dnf install gcc kernel-devel kernel-headers dkms make bzip2 perl
Step 4. Mount Virtualbox Guest Additions.
Go to Devices and click Insert Guest Additions CD Images as shown in picture below.
Then you should see a new window opened on your screen and click Run to start the installation.
If all goes well, you will see this kind of notification.
Reboot Fedora and now you should have a Fedora 25 with Virtualbox Guest Additions installed. Have a try.
This is my Fedora 25 on top of Ubuntu 16.04.
