-
-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'

-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.

-network
-
-.. code-block:: console

-Now the servers can communicate with eachother through their shared private

-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

- ipv6: None

- [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

-
-So, we are ready to destroy the network
-
-.. code-block:: console
-
- [network]: delete 3
