+Networks
+========
+
+Users can create private networks between Virtual Machines.
+
+In the following we assume that there are two active VMs (ids 141 and 142)
+connected to one public network with id 1 (default set up).
+
+.. code-block:: console
+
+ $ kamaki server addr 141
+ nic-141-0
+ firewallProfile: DISABLED
+ ipv4: 10.0.0.1
+ ipv6: None
+ mac_address: aa:00:00:23:0d:59
+ network_id: 1
+ $ kamaki server addr 142
+ nic-142-0
+ firewallProfile: DISABLED
+ ipv4: 10.0.0.3
+ ipv6: None
+ mac_address: aa:00:00:70:21:65
+ network_id: 1
+ $
+
+.. note:: In Synnefo, each VM connects to a network through a NIC. The id of a
+ nic is nic-<server id>-<increment> by convention.
+
+Let's load kamaki for networks and have a look at the current network state. We
+expect to find at least one public network (id: 1)
+
+.. code-block:: console
+
+ $ kamaki
+ kamaki v0.9 - Interactive Shell
+
+ /exit terminate kamaki
+ exit or ^D exit context
+ ? or help available commands
+ ?command help on command
+ !<command> execute OS shell command

+Create a private network
+------------------------
+
+The new network will be named 'My Private Net'
+
+.. code-block:: console
+

+
+Let's create two more networks, one for VM 141 and one for Vm 142
+
+.. code-block:: console
+
+ [network]: create 'For VM 141'

+ id: 4
+ ...
+ [network]: create 'For VM 142'

+
+Connect and disconnect
+----------------------
+
+To make a points, the networks should be connected to their respecting VMs
+
+.. code-block:: console
+
+ [network]: connect 141 4
+ [network]: connect 142 5
+ [network]:
+
+Now, let's check the current network state. We expect to see the servers
+connected to netowkrd with ids 4 and 5, but not 3.

+It is time to make meaningful connections: connect two servers to a private
+network
+
+.. code-block:: console
+
+ [network]: connect 141 3
+ [network]: connect 142 3
+ [network]:
+
+Now the servers can communicate with eachother through their shared private
+network. Let's see the network details to confirm that
+
+.. code-block:: console
+
+ [network]: info 3

+Destroy a private network
+-------------------------
+
+Attempt to destroy the public network
+
+.. code-block:: console
+
+ [network]: delete 1
+ (403) Network with id 1 is in use
+ | FORBIDDEN forbidden (Can not delete the public network.)
+ [kamaki]:
+
+.. warning:: Public networks cannot be destroyed in Synnefo
+
+Attempt to destroy the useless `For VM 141` network
+
+.. code-block:: console
+
+ [network]: delete 4
+ (403) Network with id 4 is in use
+ [network]:
+
+The attached VMs should be disconnected first (recall that the nic-141-1
+connects network with id 4 to VM with id 141)
+
+.. code-block:: console
+
+ [network]: disconnect nic-141-1
+ [network]: delete 4
+ [network]:
+
+Attempt to delete the common network. Now we know that we should disconnect the
+respective nics (nic-141-2, nic-142-2) first
+
+.. code-block:: console
+
+ [network]: disconnect nic-142-2
+ [network]: disconnect nic-141-2
+ (404) No nic nic-141-2 on server(VM) with id 141
+ | * check server(VM) with id 142: /server info 141
+ | * list nics for server(VM) with id 141:
+ | /server addr 141
+ | Network Interface nic-141-2 not found on server 141
+ [network]:
+
+Strangely, kamaki did not find any nic-141-2 nics. Why?
+
+Answer: A listing of the 141 nics shows that the network connection to network
+with id 3 is now renamed as nic-141-1
+
+.. code-block:: console
+
+ [network]: /server addr 141
+ nic-142-0
+ firewallProfile: DISABLED
+ ipv4: 10.0.0.1
+ ipv6: None
+ mac_address: aa:00:00:23:0d:59
+ network_id: 1
+ nic-142-1
+ firewallProfile: DISABLED
+ ipv4: 192.168.1.0/24
+ ipv6: None
+ mac_address: aa:00:00:23:0d:60
+ network_id: 1
+ [network]:
+
+.. warning:: Synnefo network server renames the nics of a VM whenever another
+ nic is of the same server is deleted
+
+Let's remove the correct nic, then, and check if any other nics are related to
+the network with id 3.
+
+.. code-block:: console
+
+ [network]: delete nic-141-1
+ [network]: info 3
+ attachments:
+ cidr: 192.168.1.0/24
+ cidr6: None
+ ...
+ [network]:
+
+So, we are ready to destroy the network
+
+.. code-block:: console
+
+ [network]: delete 3
