Stephen Finucane 564f5330c3 [config-ref]: update nova config options for stable/ocata 
This significant rework occurs due to recent changes in the
openstack-doc-tools project.

There are some manual fixes to the following options, where invalid rST
was included. These have been fixed on nova master but still need to be
backported to stable/ocata. This will be done separately.

- block_device_allocate_retries_interval (DEFAULT)
- torrent_images (xenserver)

Description of glance configuration options
Configuration option = Default value Description

num_retries = 0

(Integer) Enable glance operation retries.

Specifies the number of retries when uploading / downloading an image to / from glance. 0 means no retries.

api_insecure = False

(Boolean) Enable insecure SSL (https) requests to glance.

This setting can be used to turn off verification of the glance server certificate against the certificate authorities.

allowed_direct_url_schemes =

(List) List of url schemes that can be directly accessed.

This option specifies a list of url schemes that can be downloaded directly via the direct_url. This direct_URL can be fetched from Image metadata which can be used by nova to get the image more efficiently. nova-compute could benefit from this by invoking a copy when it has access to the same file system as glance.

Possible values:

  • [file], Empty list (default)

api_servers = None

(List) List of glance api servers endpoints available to nova.

https is used for ssl-based glance api servers.

Possible values:

verify_glance_signatures = False

(Boolean) Enable image signature verification.

nova uses the image signature metadata from glance and verifies the signature of a signed image while downloading that image. If the image signature cannot be verified or if the image signature metadata is either incomplete or unavailable, then nova will not boot the image and instead will place the instance into an error state. This provides end users with stronger assurances of the integrity of the image data they are using to create servers.

Related options:

  • The options in the key_manager group, as the key_manager is used for the signature validation.
debug = False (Boolean) Enable or disable debug logging with glanceclient.
