[one-users] How to interrogate the scheduler

[Carlo Daffara]

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
