Installing via the normal route didn’t work and meant I couldn’t easily resize the screen. Doing the below allowed me to use the resize easily.
- Install rpmfusion on fedora
- run `sudo yum install akmod-VirtualBox VirtualBox-guest`
- run `cd /usr/src/akmods`
- run `sudo rpm -ivh VirtualBox-*.rpm`
Once this was installed, rebooting will give you access to shared folders and fullscreen mode
Found the fix on the fedora forums for fedora 19
