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.
