When download_run_once=True it will try to first download images to host running vagrant, then upload the images from vagrant host to the vagrant vms. While trying to upload the images it will ask for a the vagrant linux user password. For small environments this behaviour is unnecessary hence changing the default to download_run_once=False inside the Vagrantfile seems like a good fix.
