Hi All,
I am using QEMU version "v5.2.0" and getting below error when running on arm64 $ qemu-system-aarch64 --version ERROR:../qom/object.c:711:object_new_with_type: assertion failed: (type != NULL) Bail out! ERROR:../qom/object.c:711:object_new_with_type: assertion failed: (type != NULL) Running GDB give below information. Is this something known.
