The starting 'x' indicates that it's the Karaf instance on which you are logged on (the local node).
+NB: if you don't see the other nodes there (whereas they should be there), it's probably due to a network issue. By default, Cellar uses multicast to discover the nodes.
+If your network or network interface don't support multicast, you have to switch to tcp-ip instead of multicast. See [Core Configuration|hazelcast] for details.

+NB: in Cellar 2.3.x, Cellar used both multicast and tcp-ip by default. Due to a change in Hazelcast, it's no more possible to have both. Now, in Cellar 3.0.x, the default
+configuration is multicast enabled, tcp-ip disabled. See [Core Configuration|hazelcast] for details.
