Hi, Avi After check host shared interrupts situation, I got a question here: If I understand correctly, current solution don't block host shared irq, just come with the performance pentry. The penalty come with host disabled irq line for a period. We have to wait guest to write EOI. But I fail to see the correctness problem here (except a lot of spurious interrupt in the guest). I've checked mail, but can't find clue about that. Can you explain the situation?
