Clearing the list explicitly was intentional. As an older version of the guest agent might not contain the 'mapping' variable in the message and then it's not sure if the disk is still there. If someone then would hot unplug a disk, it would be still reported even though it is no longer there. (That is if I would not be clearing the value)
Line 309:         elif message == 'number-of-cpus':
Line 310:             self.guestInfo['guestCPUCount'] = int(args['count'])
Line 311:         else:
Line 312:             self.log.error('Unknown message type %s', message)
