I am trying to figure out how an HVM guest is passed an interrupt. Say that a network packet has arrived and the QEMU driver in dom0 has to notify an HVM guest of the packet's arrival. Could someone please give a brief, high-level description of this process? I read the Intel Architectures Software Developer's Guide on VM Execution bits and Virtual interrupts and also some Xenwiki stuff about it but I'm still not sure what's going on. I don't have any device pass-through or stubdom or PV Drivers for my HVM guest. I would also appreciate references to some Xen files/functions related to this process.

Thanks,

John
