# -- Launching the Quantum Service
# -- CLI tools to program the Quantum-managed Cloud networking fabric
-Quantum comes with a programmatic CLI that is driven by the Quantum Web Service
-You can use the CLI by issuing the following command:

There are a few requirements to writing your own plugin:
-1) Your plugin should implement all methods defined in
-../quantum/quantum/quantum_plugin_base.QuantumPluginBase class

-2) Copy your Quantum plug-in over to the ../quantum/quantum/plugins/.. directory

3) The next step is to edit the plugins.ini file in the same directory
as QuantumPluginBase class and specify the location of your custom plugin
as the "provider"

- Unpack the tarball and run install.sh. This will install all of the
necessary pieces into /etc/xapi.d/plugins. It will also spit out the name
of the integration bridge that you'll need for your nova configuration.
+ Make sure to specify this in your nova flagfile as --flat_network_bridge.
- Run the agent [on your hypervisor (dom0)]:
$ /etc/xapi.d/plugins/ovs_quantum_agent.py /etc/xapi.d/plugins/ovs_quantum_plugin.ini
An example session looks like this:
