I tried also to hack i8259.c and the function is not called (I think).
What the first parameter of pic_set_irq_new is referred to?
Another question: why a new virtual device works anyway without interrupt mechanism? isn't it essential?
Thanks

No. You should use pic_set_irq_new. Otherwise your code will break on machines
with multiple interrupt controllers.
