OpenStack--Havana

OpenStack provides an Infrastructure as a Service (IaaS) solution through a set of
interrelated services. Each service offers an application programming interface (API) that
facilitates this integration. Depending on your needs, you can install some or all services.

For an OpenStack production deployment, most nodes must have these network interface
cards:
• One network interface card for external network traffic
• Another card to communicate with other OpenStack nodes.
For simple test cases, you can use machines with a single network interface card.

 

Configure both eth0 and eth1. The examples in this guide use the 192.168.0.x IP
addresses for the internal network and the 10.0.0.x IP addresses for the external
network. Make sure to connect your network devices to the correct network.
In this guide, the controller node uses the 192.168.0.10 and 10.0.0.10 IP addresses.
When you create the compute node, use the 192.168.0.11 and 10.0.0.11 addresses
instead. Additional nodes that you add in subsequent chapters also follow this pattern.
