Vagrant fedora 20

When first running vbox images in Fedora, you often run into an error that the kernel module is not installed.

I just had to setup vagrant for a friend, to run vbox on his fedora machine.   Thankfully, FYI, the kernel headers instructions are here.

Vagrant up !

... (note you can run vagrant on any fedora box w/ libvirt, without this hassle) ...
