It seem you'd better use GPtrArray to store the pointers,
instead of GArray that stores the full structures.

Two problems here: You pass a *pointer* to Machine, not
a Machine, so a pointer is stored into garray. And newMach
is probably never freed.
You could copy the contents of newMach into the array,
provived it's a constant-size structure with
Machine *newMach = machine_new(i,"trd11","d11","joe");
Machine m = *newMach;
g_array_append_val(garray, m);
machine_free(newMach)
But this is so obviously awkward (and incorrect, if Machine
contains any dynamically allocated data) that you don't want
to do this. Instead, use GPtrArray:
GPtrArray *array;
...
Machine *newMach = machine_new(...);
g_ptr_array_add(array, newMach);
