There are 3 identifiers for domains - ID - unique amongst all running domains on a hypervisor - Name - unique amongst all domains on a hypervisor - UUID - unique amongst all domains in a datacenter So if you want to track inactive domains, you have a choice of name or UUID. The recommendation is always that applications use UUID to track domains internally. Name should mostly be used when interacting with a user, not for internal application tracking.
