Open Stack

Hey, all.  We've got a Juno cloud, and it would be really handy for some 
of our engineers if they could see which VMs wound up on which 
hypervisors.  I'm unsure how to make that happen; I'm afraid the 
documentation on the options of the policy.json file is a bit opaque.  
How would I go about making this happen, assuming it's even possible?

Thanks!
