I use this script to setup a swapfile on a vagrant box (tested on Ubuntu 14.04)

#Usage

Inside vagrant, login as root

sudo -s

On the root home clone the repo

git clone https://github.com/emanuelzh/vagrant-swapfile.git

Give execute permissions to vagrant-swapfile.sh file

chmod u+x vagrant-swapfile.sh

Run

./vagrant-swapfile.sh
