(Type) Help string |
| [DEFAULT] console_allowed_origins = |
(ListOpt) Allowed Origin header hostnames for access to console proxy servers |
| [DEFAULT] executor_thread_pool_size = 64 |
(IntOpt) Size of executor thread pool. |
| [DEFAULT] max_concurrent_live_migrations = 1 |
(IntOpt) Maximum number of live migrations to run concurrently. This limit is enforced to avoid outbound live migrations overwhelming the host/network and causing failures. It is not recommended that you change this unless you are very sure that doing so is safe and stable in your environment. |
| [DEFAULT] password = |
(StrOpt) Password for Redis server (optional). |
| [DEFAULT] port = 6379 |
(IntOpt) Use this port to connect to redis host. |
| [DEFAULT] rpc_conn_pool_size = 30 |
(IntOpt) Size of RPC connection pool. |
| [DEFAULT] rpc_poll_timeout = 1 |
(IntOpt) The default number of seconds that poll should wait. Poll raises timeout exception when timeout expired. |

(StrOpt) Type of concurrency used. Either "native" or "eventlet" |
| [DEFAULT] secure_proxy_ssl_header = None |
(StrOpt) The HTTP header used to determine the scheme for the original request, even if it was removed by an SSL terminating proxy. Typical value is "HTTP_X_FORWARDED_PROTO". |
| [DEFAULT] update_resources_interval = 0 |
(IntOpt) Interval in seconds for updating compute resources. A number less than 0 means to disable the task completely.

| [libvirt] live_migration_downtime = 500 |
(IntOpt) Maximum permitted downtime, in milliseconds, for live migration switchover. Will be rounded up to a minimum of 100ms. Use a large value if guest liveness is unimportant. |

| [osapi_v21] extensions_whitelist = |
(ListOpt) DEPRECATED: If the list is not empty then a v2.1 API extension will only be loaded if it exists in this list. Specify the extension aliases here. This option will be removed in the near future. After that point you have to run all of the API. |

(BoolOpt) Send a single AMQP reply to call message. The current behaviour since oslo-incubator is to send two AMQP replies - first one with the payload, a second one to ensure the other has finished to send the payload. We are going to remove it in the N release, but we must keep backward compatible at the same time. This option provides such compatibility - it defaults to False in Liberty and can be turned on for early adopters with new installations or for testing. This option will be removed in the Mitaka release. |
| [oslo_messaging_rabbit] kombu_reconnect_timeout = 60 |

The current behaviour since oslo-incubator is to send two AMQP replies - first one with the payload, a second one to ensure the other has finished to send the payload. We are going to remove it in the N release, but we must keep backward compatible at the same time. This option provides such compatibility - it defaults to False in Liberty and can be turned on for early adopters with new installations or for testing. This option will be removed in the Mitaka release. |
| [oslo_middleware] secure_proxy_ssl_header = X-Forwarded-Proto |

| [vmware] insecure = False |

| [vmware] serial_port_proxy_uri = None |
(StrOpt) Identifies a proxy service that provides network access to the serial_port_service_uri. This option is ignored if serial_port_service_uri is not specified. |
| [vmware] serial_port_service_uri = None |
(StrOpt) Identifies the remote system that serial port traffic will be sent to. If this is not set, no serial ports will be added to the created VMs. |
| [vnc] enabled = True |
(BoolOpt) Enable VNC related features |

(StrOpt) Location of nova xvp VNC console proxy, in the form "http://127.0.0.1:6081/console" |
| [workarounds] handle_virt_lifecycle_events = True |
(BoolOpt) Whether or not to handle events raised from the compute driver's 'emit_event' method. These are lifecycle events raised from compute drivers that implement the method. An example of a lifecycle event is an instance starting or stopping. If the instance is going through task state changes due to an API operation, like resize, the events are ignored. However, this is an advanced feature which allows the hypervisor to signal to the compute service that an unexpected state change has occurred in an instance and the instance can be shutdown automatically - which can inherently race in reboot operations or when the compute service or host is rebooted, either planned or due to an unexpected outage. Care should be taken when using this and sync_power_state_interval is negative since then if any instances are out of sync between the hypervisor and the Nova database they will have to be synchronized manually.
