The error message for a "stepping" value that is out of bounds is a
bit odd:
$ qemu-system-x86_64 -cpu qemu64,stepping=16
qemu-system-x86_64: can't apply global qemu64-x86_64-cpu.stepping=16:
Property .stepping doesn't take value 16 (minimum: 0, maximum: 15)
The "can't apply global" part is an unfortunate artifact of -cpu's
implementation. Left for another day.
The remainder feels overly verbose. Change it to
qemu64-x86_64-cpu: can't apply global qemu64-x86_64-cpu.stepping=16:
parameter 'stepping' can be at most 15
Likewise for "family", "model", and "tsc-frequency".
