Maintenance¶
Once you are running nova, the following information is extremely useful.
Admin Guide: A collection of guides for administrating nova.
Warning
This guide was imported during the Pike cycle and is a bit out of date. It will be updated during Queens to be more accurate.
Upgrades: How nova is designed to be upgraded for minimal service impact, and the order you should do them in.
Quotas: Managing project quotas in nova.
Aggregates: Aggregates are a useful way of grouping hosts together for scheduling purposes.
Filter Scheduler: How the filter scheduler is configured, and how that will impact where compute instances land in your environment. If you are seeing unexpected distribution of compute instances in your hosts, you'll want to dive into this configuration.
Exposing custom metadata to compute instances: How and when you might want to extend the basic metadata exposed to compute instances (either via metadata server or config drive) for your specific purposes.
