Nova

A walkthrough of OpenStack’s three core services: Keystone multi-domain support, service/endpoint registration and policy-file authorization; Nova’s modules (api/scheduler/conductor/compute/novncproxy), the message queue and the differential disk; and the Glance image service switched to a Swift object-storage backend.

From the web dashboard to the CLI, a complete walkthrough of provisioning OpenStack cloud servers: creating and deleting tenants/users/images/flavors/networks/routers/security groups/key pairs/floating IPs, plus iptables SNAT/DNAT and Nova cell_v2 discover_hosts troubleshooting.
