The repository below resizes the vagrant box automatically, and I prefer this way.

https://github.com/SydOps/vagrant-box-resize

Here are the manual tasks with my updates and fork from christopher-hopper/vm-resize-hard-disk.md. But one issue is, after I manually resize, I found I can't use packer to re-baker vagrant box again.

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.
