<type 'exceptions.NameError'>

so i found that in nova/object/aggregate.py function
update_aggregate_for_instance using LOG.exception to write down message
in nova-api.log when instance.save error and throw exception, bug in
this module does not defined LOG, so it will report  Unexpected API
Error.
