charset="utf-8" Commit 741d4086c8 "migration: Use proper types in json" (v2.12.0) switched MigrationParameters to narrower integer types, and removed the simplified qmp_migrate_set_parameters()'s argument checking accordingly. Good idea, except qmp_migrate_set_parameters() takes MigrateSetParameters, not MigrationParameters. Its job is updating migrate_get_current()->parameters (which *is* of type MigrationParameters) according to its argument. The integers now get truncated silently. Reproducer: ---> {'execute': 'query-migrate-parameters'} <--- {"return": {[...] "compress-threads": 8, [...]}} ---> {"execute": "migrate-set-parameters", "arguments": {"compress-thre= ads": 257}} <--- {"return": {}} ---> {'execute': 'query-migrate-parameters'} <--- {"return": {[...] "compress-threads": 1, [...]}} Fix by resynchronizing MigrateSetParameters with MigrationParameters.
