Here's a differently terrible hack. We have

optarg --------> QObject --------> QAPI type
Idea: hack the QObject. If we're working for -object, and QObject maps
key "qom-type" to value "memory-backend-ram", get the value of
host-nodes, and if it's a string, parse it into a list like the opts
visitor does, and put that back, replacing the string value.
Same for other uses of Memdev and NumaNodeOptions with -object, if they
exist.
This doesn't help with backwards compatibility, since keyval loses the
first of host-nodes=0,host-nodes=4.
I would rather keep the OptsVisitor here. Do the same check for JSON
syntax that you have in qobject_input_visitor_new_str, and whenever you
need to walk all -object arguments, use something like this:
typedef struct ObjectArgument {
const char *id;
QDict *json; /* or NULL for QemuOpts */
QSIMPLEQ_ENTRY(ObjectArgument) next;
}
I already had patches in my queue to store -object in a GSList of
dictionaries, changing it to use the above is easy enough.
