If I did not. I think this is a big problem. We need to at least
zeroize the queues (e.g. on system reset) to avoid leaking

ap-passthrough. Or am I wrong?
I do not have a definitive answer, I will have to look into it.
I'm thinking that since we are using ap-passthrough, the AP bus
running on the guest would be responsible for handling reset possibly
by resetting or zeroizing its queues. I'll get back to you on this.
You are on the wrong track. What I'm talking about is the responsibility
of the hypervisor and not the responsibility of the guest.
