+vhost/virtio-user loopback server mode test plan
+================================================
 
 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.
+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.
