Description of configuration options for api

Configuration option = Default value	Description
[DEFAULT]
enable_new_services = True	(BoolOpt) Services to be added to the available pool on create
enabled_apis = ec2, osapi_compute, metadata	(ListOpt) A list of APIs to enable by default
enabled_ssl_apis =	(ListOpt) A list of APIs with enabled SSL
instance_name_template = instance-%08x	(StrOpt) Template string to be used to generate instance names
max_header_line = 16384	(IntOpt) Maximum line size of message headers to be accepted. max_header_line may need to be increased when using large tokens (typically those generated by the Keystone v3 API with big service catalogs).
multi_instance_display_name_template = %(name)s-%(uuid)s	(StrOpt) When creating multiple instances with a single request using the os-multiple-create API extension, this template will be used to build the display name for each instance. The benefit is that the instances end up with different hostnames. To restore legacy behavior of every instance having the same name, set this option to "%(name)s". Valid keys for the template are: name, uuid, count.
non_inheritable_image_properties = cache_in_nova, bittorrent	(ListOpt) These are image properties which a snapshot should not inherit from an instance
null_kernel = nokernel	(StrOpt) Kernel image that indicates not to use a kernel, but to use a raw disk image instead
osapi_compute_ext_list =	(ListOpt) Specify list of extensions to load when using osapi_compute_extension option with nova.api.openstack.compute.contrib.select_extensions
osapi_compute_extension = ['nova.api.openstack.compute.contrib.standard_extensions']	(MultiStrOpt) osapi compute extension to load
osapi_compute_link_prefix = None	(StrOpt) Base URL that will be presented to users in links to the OpenStack Compute API
osapi_compute_listen = 0.0.0.0	(StrOpt) The IP address on which the OpenStack API will listen.
osapi_compute_listen_port = 8774	(IntOpt) The port on which the OpenStack API will listen.
osapi_compute_workers = None	(IntOpt) Number of workers for OpenStack API service. The default will be the number of CPUs available.
osapi_hide_server_address_states = building	(ListOpt) List of instance states that should hide network info
servicegroup_driver = db	(StrOpt) The driver for servicegroup service (valid options are: db, zk, mc)
snapshot_name_template = snapshot-%s	(StrOpt) Template string to be used to generate snapshot names
use_forwarded_for = False	(BoolOpt) Treat X-Forwarded-For as the canonical remote address. Only enable this if you have a sanitizing proxy.
