+More Netwrok Cards
+==================
+
+When the cluster configuration changes (add / remove nodes), a big amount of
+data is going to be "moved" between the nodes.
+If our hosts have a second network card, it can be dedicated to that scope.
+Doing so, the other network card will manage only the traffic generated by
+guests and will better manage corosync messages (or other cluster manager).
+
+**Important:** if eth0 has in ip in the network 192.168.20.0/24, use a different
+network address for eth1, e.g 192.168.21.0/24.
+
+::
+
+    eth0 192.168.20.30/24
+    eth1 192.168.21.5/24
+    
+    sheep -i host=192.168.21.5 port=3333
+
+
+Note: you can use any port out of the range 1-1024.
