I read this thread as asking the question:

    If VM management is viewed as an optimization problem,
    then what exactly is the function that you are optimizing and what are the constraints?

If you could express that well with a even a very loose model, then
the code could be reviewed to see if it was really doing what was intended
and assumptions could be tested.

This seems like a reasonable request.
