Configuration Guide¶
The static configuration for nova lives in two main files: nova.conf and
policy.yaml. These are described below. For a bigger picture view on
configuring nova to solve specific problems, refer to the Nova Admin
Guide.
Configuration¶
Configuration Guide: Detailed configuration guides for various parts of your Nova system. Helpful reference for setting up specific hypervisor backends.
Config Reference: A complete reference of all configuration options available in the
nova.conffile.
Sample Config File: A sample config file with inline documentation.
Policy¶
Nova, like most OpenStack projects, uses a policy language to restrict permissions on REST API actions.
Policy Concepts: Starting in the Ussuri release, Nova API policy defines new default roles with system scope capabilities. These new changes improve the security level and manageability of Nova API as they are richer in terms of handling access at system and project level token with ‘Read’ and ‘Write’ roles.
Policy Reference: A complete reference of all policy points in nova and what they impact.
Sample Policy File: A sample nova policy file with inline documentation.
Extra Specs¶
Nova uses flavor extra specs as a way to provide additional information to instances beyond basic information like amount of RAM or disk. This information can range from hints for the scheduler to hypervisor-specific configuration instructions for the instance.
