Public bug reported: A recent patch [1] has merged in nova, which sanitizes the nova instance object, making it picklable. The sanitized instance object no longer has a _context attribute, which means that lazy-loading attributes are no longer loadable [2].
This can be an issue whenever a config drive has to be built for an instance, as InstanceMetadata.metadata_for_config_drive needs some unloaded attributes (device_metadata). This issue has been seen to affect mostly rebuild, unshelve, rescue operations.
