Creating VM images is always a pain to users, and it is especially the case
for those who want to set up the ACRN sample application which needs two
different VM images, one with graphical desktop and the other optimized for
real-time.
This patch introduces the so-called "image builder" utility which is a set
of scripts that can automate the creation of those VM images. The scripts
will take care of:
- Forking image files based on Ubuntu cloud images and enlarge the root
file system per needs.
- Setting up users and passwords.
- Installing necessary packages to run either the graphical desktop or
real-time applications.
- Specific to the RT VM image, disabling services and tweaking kernel
command line for optimized real-time performance.
- Copying the sample applications into the images so that users can
start them directly, after they launch the VMs.
