If possible I'd like to avoid re-inventing the wheel, 
and I could imagine that my idea is of general interest.

There is an early presentation
http://www.slideshare.net/llorente/vm-management-for-greenit-data-centers

which covers exactly what I've been looking for, especially the 
"VM Consolidation Scheduler" mentioned on p14. 
Is any code for this available ?

Yours,
Steffen
