While the FW_CFG_DATA_GENERATOR_INTERFACE is only consumed by a device only available using system-mode (fw_cfg), it is implemented by a crypto component (tls-cipher-suites) which is always available when crypto is used. Commit69699f3055introduced the following error in the qemu-storage-daemon binary: $ echo -e \ '{"execute": "qmp_capabilities"}\r\n{"execute": "qom-list-types"}\r\n{"execute": "quit"}\r\n' \ | storage-daemon/qemu-storage-daemon --chardev stdio,id=qmp0 --monitor qmp0 {"QMP": {"version": {"qemu": {"micro": 50, "minor": 1, "major": 5}, "package": ""}, "capabilities": ["oob"]}} {"return": {}} missing interface 'fw_cfg-data-generator' for object 'tls-creds' Aborted (core dumped) Since QOM dependencies are resolved at runtime, this issue could not be triggered at linktime, and we don't have test running the qemu-storage-daemon binary. Fix by always registering the QOM interface.
