From: BillXiang <xiangwench...@gmail.com> Clean up commit 7c211eb078c4 ("vhost-user: Skip unnecessary duplicated VHOST_USER_SET_LOG_BASE requests") which has added VHOST_USER_SET_LOG_BASE to vhost_user_per_device_request and will not send it in vhost_user_write when vq_index != 0 but still wait for replies in vhost_user_set_log_base for those not sent msgs which will cause qemu hangs up. So we add check in this patch to read reply only when vq_index == 0.
