Needs more documentation
Issues about troubleshooting sound should be present, since we would be using this for gaming. The concerns about others not being able to recover their passwords are not valid. Follow the instructions carefully and you should have no problem.
Also something that should be discussed in the documentation is how the password will work if you save an image of your machine and then re-instantiate it.
Password issue seems fixed but sound? There is no sound driver installed and needs to be added.
