It's a passtrough system where the guest is given a virtual function and is using MSIX to recieve the interrupts. I am trying to understand how is the guest supposed to recieve the interrupt: Is it handled by dom0 which is using event channels to pass the interrupt to domU, or is handled directly by domU. Please send pointers to the code. Thanks in advance, eli;
