There is actually already a scheduler that does it, it uses the "packing
policy":
Packing Policy
Target: Minimize the number of cluster nodes in use
Heuristic: Pack the VMs in the cluster nodes to reduce VM fragmentation
Implementation: Use those nodes with more VMs running first
RANK = RUNNING_VMS

Oggetto: [one-users] How to interrogate the scheduler
I'm writing a program that has to minimize the number of running hosts.
I need to know, before that I command a VM reschedule or a template
instantiation, if it is possible to ask to the scheduler which will be the
selected host.
Kind regards,
Marco Fanti
