> +Description
> +===========
> +
> +Without virtio-user server mode support, if the vhost-user backend
> +restarts, there’s no way for it to reconnect to virtio-user. To address this,
> support for server mode has been added.
> +In this mode the socket file is created by virtio-user, which the backend
> connects to.
> +This means that if the backend restarts, it can reconnect to virtio-user and
> continue communications.
> +Design below five cases for virtio-user server mode test.
