When I was digging into live migration code, i noticed that the same MR name may

Since nvdimm devices do not have parent-bus, it will trigger the abort() in that
function.
I see. The other devices that use a constant name are on a bus so the
abort doesn't trigger.
However, the MR name must be the same across the two machines. Indices
are not friendly to hotplug. Even though hotplug isn't supported now,
we should prepare and try not to change migration format when we support
hotplug in the future.
Thanks for your reminder.
Is there any other fixed value that we can use, for example the base
address of the NVDIMM?
How about use object_get_canonical_path(OBJECT(dev)) (the @dev is NVDIMM
device) ?
