@ -12,134 +12,170 @@ New, updated, and deprecated options in Mitaka for Compute
* - Option = default value
- (Type) Help string
* - ``[DEFAULT] disk_weight_multiplier = 1.0``
- (FloatOpt) Multiplier used for weighing free disk space. Negative numbers mean to stack vs spread.
* - ``[DEFAULT] notification_format = both``
- (StrOpt) Specifies which notification format shall be used by nova.
* - ``[DEFAULT] soft_affinity_weight_multiplier = 1.0``
- (FloatOpt) Multiplier used for weighing hosts for group soft-affinity. Only a positive value is meaningful. Negative means that the behavior will change to the opposite, which is soft-anti-affinity.
* - ``[DEFAULT] soft_anti_affinity_weight_multiplier = 1.0``
- (FloatOpt) Multiplier used for weighing hosts for group soft-anti-affinity. Only a positive value is meaningful. Negative means that the behavior will change to the opposite, which is soft-affinity.
* - ``[DEFAULT] use_neutron = False``
- (BoolOpt) Whether to use Neutron or Nova Network as the back end for networking. Defaults to False (indicating Nova network). Set to True to use neutron.
* - ``[cache] backend = dogpile.cache.null``
- (StrOpt) Dogpile.cache backend module. It is recommended that Memcache with pooling (oslo_cache.memcache_pool) or Redis (dogpile.cache.redis) be used in production deployments. Small workloads (single process) like devstack can use the dogpile.cache.memory backend.
* - ``[cache] backend_argument = []``
- (MultiStrOpt) Arguments supplied to the backend module. Specify this option once per argument to be passed to the dogpile.cache backend. Example format: "<argname>:<value>".
* - ``[cache] config_prefix = cache.oslo``
- (StrOpt) Prefix for building the configuration dictionary for the cache region. This should not need to be changed unless there is another dogpile.cache region with the same configuration name.
* - ``[cache] debug_cache_backend = False``
- (BoolOpt) Extra debugging from the cache backend (cache keys, get/set/delete/etc calls). This is only really useful if you need to see the specific cache-backend get/set/delete calls with the keys/values. Typically this should be left set to false.
* - ``[cache] enabled = False``
- (BoolOpt) Global toggle for caching.
* - ``[cache] expiration_time = 600``
- (IntOpt) Default TTL, in seconds, for any cached item in the dogpile.cache region. This applies to any cached method that doesn't have an explicit cache expiration time defined for it.
* - ``[cache] memcache_dead_retry = 300``
- (IntOpt) Number of seconds memcached server is considered dead before it is tried again. (dogpile.cache.memcache and oslo_cache.memcache_pool backends only).
* - ``[cache] memcache_pool_connection_get_timeout = 10``
- (IntOpt) Number of seconds that an operation will wait to get a memcache client connection.
* - ``[cache] memcache_pool_maxsize = 10``
- (IntOpt) Max total number of open connections to every memcached server. (oslo_cache.memcache_pool backend only).
* - ``[cache] memcache_pool_unused_timeout = 60``
- (IntOpt) Number of seconds a connection to memcached is held unused in the pool before it is closed. (oslo_cache.memcache_pool backend only).
* - ``[cache] memcache_servers = localhost:11211``
- (ListOpt) Memcache servers in the format of "host:port". (dogpile.cache.memcache and oslo_cache.memcache_pool backends only).
* - ``[cache] memcache_socket_timeout = 3``
- (IntOpt) Timeout in seconds for every call to a server. (dogpile.cache.memcache and oslo_cache.memcache_pool backends only).
* - ``[cache] proxies =``
- (ListOpt) Proxy classes to import that will affect the way the dogpile.cache backend functions. See the dogpile.cache documentation on changing-backend-behavior.
* - ``[cells] instance_update_sync_database_limit = 100``
- (IntOpt) Instance update sync database limit Number of instances to pull from the database at one time for a sync. If there are more instances to update the results will be paged through.
Possible values:
* Number of instances.
Services which consume this:
* nova-cells
Related options:
* None
* - ``[glance] verify_glance_signatures = False``
- (BoolOpt) Require Nova to perform signature verification on each image downloaded from Glance.
* - ``[libvirt] live_migration_inbound_addr = None``
- (StrOpt) Live migration target ip or hostname (if this option is set to None, which is the default, the hostname of the migration target compute node will be used)
* - ``[libvirt] live_migration_tunnelled = None``
- (BoolOpt) Whether to use tunnelled migration, where migration data is transported over the libvirtd connection. If True, we use the VIR_MIGRATE_TUNNELLED migration flag, avoiding the need to configure the network to allow direct hypervisor to hypervisor communication. If False, use the native transport. If not set, Nova will choose a sensible default based on, for example the availability of native encryption support in the hypervisor.
* - ``[libvirt] realtime_scheduler_priority = 1``
- (IntOpt) In a realtime host context vCPUs for guest will run in that scheduling priority. Priority depends on the host kernel (usually 1-99)
* - ``[neutron] auth_type = None``
- (Opt) Authentication type to load
* - ``[osapi_v21] project_id_regex = None``
- (StrOpt) DEPRECATED: The validation regex for project_ids used in urls. This defaults to [0-9a-f\-]+ if not set, which matches normal uuids created by keystone.
* - ``[oslo_policy] policy_default_rule = default``
- (StrOpt) Default rule. Enforced when a requested rule is not found.
* - ``[oslo_policy] policy_dirs = ['policy.d']``

- (StrOpt) The JSON file that defines policies.
* - ``[vnc] novncproxy_host = 0.0.0.0``
