Hi Yuanhan,
As I understand, the dead loop happened here (virtio_send_command):
while (vq->vq_used_cons_idx == vq->vq_ring.used->idx) {
rte_rmb();
usleep(100);
}
Could you explain why wrong config reading caused that and how correct reading
helps to avoid?

Fix the max virtio queue pair read issue.
Control queue can't work for vhost-user mulitple queue mode,
so introduce a counter to void the dead loop when polling
the control queue.
