From: Daniel Hansel <daniel.hansel@xxxxxxxxxxxxxxxxxx> We have seen an issue on s390x platform where domain XMLs larger than 1MB were used. The define command was finished successfully. The dumpxml command was not successful (i.e. could not encode message payload). Enlarged message related sizes (e.g. maximum string size, message size, etc.) to handle larger system configurations used on s390x platform.
