What its trying to tell you in a wonderfully user intutitive manner is

"Another virtual machine is loaded and you can only have one hypervisor
 at a time using the CPU hardware assist"

Or in even plainer English "Hey you don't need virtualbox, the stuff
supplied with Fedora will just work"

It ought to be sufficient to "rmmod kvm" I suspect, however firing up the
virtual machine manager and creating a new virtual machine via kvm should
also "just work"
