As long as those node IDs don't get stored persistently for future
use, using them (despite being a Xen internal representation)
ought to be fine. My concern really is that such Xen internals may
easily get mis-used in the tool stack, e.g. assuming that they won't
change across reboots (perhaps after a hypervisor update).
