This cookbook configures the networking required for OpenStack, specifically for the compute service nova.
Chef 0.10.0 or higher required (for Chef environment use)
- CentOS >= 6.3
- Ubuntu >= 12.04
The following cookbooks are dependencies:
- mysql
- nova
- osops-utils
- sysctl
nova["network"]["provider"]
- The networking provider to use with nova. By default this is set to nova, but can be changed to quantum.nova["networks"]
- An array of networks to be assigned to instances on creation

The recipes nova-controller and nova-compute are used in their corresponding roles single-controller and single-compute. The role quantum-network-manager has been added to indicate a node that is running l3_agent, dhcp_agent, and ovs_plugin.
The nova-network cookbook has a resource and provider named networks. This LWRP provides the ability to create a fixed network, delete a fixed network, create a floating ip network, and delete a floating ip network.
