The typing of this is off -- try "make check-dev" in qemu.git/python to see:

iotests.py:467: error: Item "None" of "Optional[QEMUMonitorProtocol]"
has no attribute "cmd"  [union-attr]
iotests.py:467: error: Argument after ** must be a mapping, not
"Optional[Dict[str, object]]"  [arg-type]
iotests.py:467: error: Incompatible return value type (got
"Union[object, Any]", expected "Dict[str, Any]")  [return-value]
Found 3 errors in 1 file (checked 32 source files)

You need to assert that self._qmp is not None for the first; the
second seems to do with a potentially "None" argument for args, and
the third has to do with the difference between returning the entire
raw response and just the return value.

I started making a fixup branch, but I stopped around here.
