If you find that vagrant box list somehow does not contain a box you previously had, you can sometimes add the box back if you still have the sources for it in ~/.vagrant.d/boxes.

$ cd ~/.vagrant.d/boxes/precise64/0/virtualbox/
$ tar czf ~/precise64.box .
$ vagrant box add precise64 ~/precise64.box
