+Print UUIDs instead of names. This is useful for following
+a guest even when the guest is migrated or renamed, or when
+two guests happen to have the same name.
+
+Note that only domains that we fetch from libvirt come with UUIDs.
+For disk images, we still print the disk image name even when
+this option is specified.
