Fedora 20 (Heisenbug) is currently the latest release and if you want to try it on VirtualBox then install the guest additions for full functionality.
Installation is simple and takes a few steps, but involves download and updates which would require some bandwidth.
The Guest Additions are compiled from source and loaded as a module.
1. Update Fedora
The first thing to do is to upgrade all packages and make the system uptodate.
$ sudo yum distro-sync
2. Install kernel headers and build tools
VirtualBox guest additions are always compiled so they need necessary build tools and kernel libraries. Install them with the following command.
$ yum -y install kernel-devel kernel-headers dkms gcc gcc-c++
After upgrading and installing kernel headers, reboot the system.
3. Compile virtualbox guest additions
Click on Devices > Insert guest additions CD image on the VirtualBox window menu.
The cd image is now available in fedora at /dev/cdrom or /dev/sr0.
Create a directory at home and mount the cd in it.
$ mkdir vboxcd $ sudo mount /dev/cdrom ~/vboxcd [sudo] password for silver: mount: /dev/sr0 is write-protected, mounting read-only
$ ls 32Bit cert VBoxSolarisAdditions.pkg 64Bit OS2 VBoxWindowsAdditions-amd64.exe AUTORUN.INF runasroot.sh VBoxWindowsAdditions.exe autorun.sh VBoxLinuxAdditions.run VBoxWindowsAdditions-x86.exe
Next run the VBoxLinuxAdditions.run script. The output should look similar to this
$ sudo ./VBoxLinuxAdditions.run Verifying archive integrity... All good. Uncompressing VirtualBox 4.3.6 Guest Additions for Linux............

Installing graphics libraries and desktop services componen[ OK ] $
The line that builds the VirtualBox Guest additions kernel modules is the important one and must not fail
Building the VirtualBox Guest Additions kernel modules [ OK ]
Done, Now reboot.
4. Verify that guest additions are loaded
After the reboot the screen resolution of fedora guest should adapt to virtualbox window size which indicates that the guest additions are working. You can additionally verify that the kernel modules are loaded or not, with the following command
$ lsmod | grep -i vbox vboxsf 43786 0 vboxvideo 12658 1 drm 283349 2 vboxvideo vboxguest 231692 8 vboxsf $
The vboxguest module indicates that virtualbox guest additions kernel module is loaded and working.
5. Configure shared folders
The last thing is to configure shared folders so that you can easily exchange files between the host and guest OS. Click on "Devices > Shared Folder Settings" in the Virtualbox window. Click the icon on right to add a new shared folder.
Select the directory on your host system that is to be shared with the guest Fedora 20.
Make sure to give a proper folder name, since it would be used to mount the directory inside Fedora.
Check "Make Permanent" if you want shared folder setting persistent. Permanent shared folders are listed under Machine Folders, where as the non-permanent ones go under the Transient Folders list.
After selecting the folder to share, now mount the folder inside Fedora using the folder name specified earlier. The command to use is mount
$ sudo mount -t vboxsf enlightened ./vboxshared OR $ sudo mount.vboxsf enlightened ./vboxshared
vboxshared is the name of the directory where we mount the shared folder. Make sure that the directory exists. The mount command would now show that the directory is mounted
$ mount | grep vboxsf none on /home/silver/vboxshared type vboxsf (rw,nodev,relatime)
Finally you have VirtualBox Guest Additions Installed on Fedora. Now you should be able to get the native resolution, and be able to copy paste stuff across Fedora and the host OS.
It will also enable shared folders so that you can automatically share files across host and guest OS.
