Bug Description

When nova is set to use QuantumManager as its network manager both nova-compute and nova-network fail to start:

/etc/nova/nova.conf
network_manager=quantum.manager.QuantumManager

/etc/quantum/quantum.conf
core_plugin = quantum.plugins.openvswitch.ovs_quantum_plugin.OVSQuantumPluginV2

This bug is due to misconfiguration for network_manager in nova.conf.
We need to set a subclass of NetworkManager for network_manager.

When quantum is enabled, we do not need to set network_manager explicitly since nova-network is not launched.
(The default value is nova.network.manager.VlanManager, but we need not to change it)

Matt,

From Folsom-2 nova-network and the Quantum Manager are not used anymore to communicate with Quantum, as nova call directly the Quantum API. Hence nova-network should not run at all. An admin guide which will guide you through the process of installing and configuring Quantum v2 is in preparation and should be available as a draft by the end of this week. In the meanwhile, you can look at devstack to get a grasp of how quantum and the various agents have been configured.

Can you please tell me which version of the packages are you using? This might help us understand if there's a packaging issue to be addressed.

Thanks for the update. I will wait for the updated documentation.

I was running the latest packages from:

ppa:openstack-ubuntu-testing/folsom-trunk-testing

I think that's actually wontfix, based on comment 2. Feel free to reopen (set status back to New) if you disagree.
