Bin Wu a3614c65cf hw/virtio/vring/event_idx: fix the vring_avail_event error ... The event idx in virtio is an effective way to reduce the number of interrupts and exits of the guest. When the guest puts an request into the virtio ring, it doesn't exit immediately to inform the backend. Instead, the guest checks the "avail" event idx to determine the notification. In virtqueue_pop, when a request is poped, the current avail event idx should be set to the number of vq->last_avail_idx. Signed-off-by: Bin Wu <wu.wubin@huawei.com> Reviewed-by: Michael S.
