Hi Alejandro,

> Yes, the code was not aware of that possibility. Being honest, I knew about that, but not in my mind when implementing the code. I have just cards where each PF even VF have their own VFIO group. This could be a problem for testing.
> Anatoly, do you have a system with that peculiarity?
 
I think if you compile an old kernel (like a 3.6), you should be able to reproduce the behavior. (at least I am able to do this with an old kernel)

Anatoly
