Here you go - http://msdn.microsoft.com/en-us/library/windows/hardware/ff553105(v=vs.85).aspx
Already done in virtio-net for two reasons: 1. we could configure virtio-net to notify QEMU in a hacky way (write 1 to VIRTIO_PCI_ISR register) that there was a bugckeck .It was very useful debugging complex WHQL issues that involved host networking. 2. Store additional information (for example time stamps of last receive packet, last interrupt and etc) in crash dump.
