To be clear, what do you mean exactly by "live-evacuate"? I assume you 
mean live migration of all instances off each (disabled) compute node 
*before* you upgrade it. I wanted to ask because "evacuate" as a server 
operation is something else entirely (it's rebuild on another host which 
is definitely disruptive to the workload on that server).
