Test Scenario :

one server two clients create Entries in all vms c1 : register (k1,k2,k3,k4,k5) c2 : put (k1 ->
vm2-key-1) and (k6 -> vm2-key-6) c1 : validate (r.getEntry("key-1").getValue() == "vm2-key-1")
(r.getEntry("key-6").getValue() == "key-6") // as it is not registered s1 : stop server c2 : put
(k1 -> vm2-key-1) and (k6 -> vm2-key-6) c1 : validate (r.getEntry("key-1").getValue() ==
"vm2-key-1") (r.getEntry("key-6").getValue() == "key-6") // as it is not registered *
