qemu-kvm/hw/virtio_config.h:
#define VIRTIO_CONFIG_S_ACKNOWLEDGE 1
#define VIRTIO_CONFIG_S_DRIVER 2
#define VIRTIO_CONFIG_S_DRIVER_OK 4
#define VIRTIO_CONFIG_S_FAILED 0x80

virtio-spec:
ACKNOWLEDGE(1) :
DRIVER(2) :
DRIVER_OK(3) :
FAILED(128) :

The spec refers to bit numbers and the headers use absolute numbers,
they are not consistent.

it shoule be 'FAILED(8)'.
2^(8-1) = 128
