> -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.
> +Virtio-user server mode is a feature to enable the virtio-user as the
> +server, vhost as the client, then when the vhost-user is killed then
> +re-launched, the virtio-user can connect back to vhost-user again; at
> +another hand, virtio-user can be reconnected to vhost-user when virtio-
> user is killed or rebooted.
> +This test plan ensure the reconnect can work well with current test setup.
