The Flavor Class

The Flavor class inherits from Resource.

class openstack.compute.v2.flavor.Flavor(_synchronized=False, connection=None, **attrs)

The base resource

  • _synchronized (bool) – This is not intended to be used directly. See new() and existing().

  • connection (openstack.connection.Connection) – Reference to the Connection being used. Defaults to None to allow Resource objects to be used without an active Connection, such as in unit tests. Use of self._connection in Resource code should protect itself with a check for None.

A dictionary of the flavor’s extra-specs key-and-value pairs.

classmethod list(session, paginated=True, base_path='/flavors/detail', allow_unknown_params=False, **params)

This method is a generator which yields resource objects.

This resource object list generator handles pagination and takes query params for response filtering.

  • session (Adapter) – The session to use for making this request.

  • paginated (bool) – True if a GET to this resource returns a paginated series of responses, or False if a GET returns only one page of data. When paginated is False only one page of data will be returned regardless of the API’s support of pagination.

  • base_path (str) – Base part of the URI for listing resources, if different from base_path.

  • allow_unknown_params (bool) – True to accept, but discard unknown query parameters. This allows getting list of ‘filters’ and passing everything known to the server. False will result in validation exception when unknown query parameters are passed.

  • params (dict) – These keyword arguments are passed through the _transpose() method to find if any of them match expected query parameters to be sent in the params argument to get(). They are additionally checked against the base_path format string to see if any path fragments need to be filled in by the contents of this argument.


A generator of Resource objects.


MethodNotSupported if Resource.allow_list is not set to True.


InvalidResourceQuery if query contains invalid params.

add_tenant_access(session, tenant)

Adds flavor access to a tenant and flavor.

remove_tenant_access(session, tenant)

Removes flavor access to a tenant and flavor.


Lists tenants who have access to a private flavor

By default, only administrators can manage private flavor access. A private flavor has is_public set to false while a public flavor has is_public set to true.


List of dicts with flavor_id and tenant_id attributes


Fetch extra_specs of the flavor

Starting with 2.61 extra_specs are returned with the flavor details, before that a separate call is required.

create_extra_specs(session, specs)

Creates extra specs for a flavor

get_extra_specs_property(session, prop)

Get individual extra_spec property

update_extra_specs_property(session, prop, val)

Update An Extra Spec For A Flavor

delete_extra_specs_property(session, prop)

Delete An Extra Spec For A Flavor
