Compute node

The compute node systems act as KVM hypervisors and run the nova-compute and openvswitch-agent services.

The Physical architecture section of the design document should also contain a section on the physical network architecture of the deployment. In this section, each of the segmented networks should be defined. Connectivity for each physical host to each network should also be defined.

The Packstack installation tool doesn't allow the specification of an external network for API traffic. As such, we'll use three physical networks in this deployment: a management network that is routable to the intranet, a provider network that provides floating IPs for the instances, and a tenant network for instance traffic. The following network definitions should be added to the Physical architecture section.
