            logging.info('Job-%s: Locks acquired', self['id'])

            self.checkpoint()

            # Check if VM is stopped:

            if not self._check_status(vm_id, 'stopped'):

                raise JobCancelError('vm is not stopped')

            # Create storages on destination:

            old_new_disk_mapping = {} # Mapping between old and new disk names

            self.report('create volumes')
