+==========================================
+Example Spec - The title of your blueprint
+==========================================
+
+Include the URL of your launchpad blueprint:
+
+https://blueprints.launchpad.net/nova/+spec/example
+
+Introduction paragraph -- why are we doing anything? A single paragraph of
+prose that operators can understand. The title and this first paragraph
+should be used as the subject line and body of the commit message
+respectively.
+
+Some notes about the nova-spec and blueprint process:
+
+* Not all blueprints need a spec. For more information see
+  https://docs.openstack.org/nova/latest/contributor/blueprints.html#specs
+
+* The aim of this document is first to define the problem we need to solve,
+  and second agree the overall approach to solve that problem.
+
+* This is not intended to be extensive documentation for a new feature.
+  For example, there is no need to specify the exact configuration changes,
+  nor the exact details of any DB model changes. But you should still define
+  that such changes are required, and be clear on how that will affect
+  upgrades.
+
+* You should aim to get your spec approved before writing your code.
+  While you are free to write prototypes and code before getting your spec
+  approved, its possible that the outcome of the spec review process leads
+  you towards a fundamentally different solution than you first envisaged.
+
+* But, API changes are held to a much higher level of scrutiny.
+  As soon as an API change merges, we must assume it could be in production
+  somewhere, and as such, we then need to support that API change forever.
+  To avoid getting that wrong, we do want lots of details about API changes
+  upfront.
+
+Some notes about using this template:
+
+* Your spec should be in ReSTructured text, like this template.
+
+* Please wrap text at 79 columns.
+
+* The filename in the git repository should match the launchpad URL, for
+  example a URL of: https://blueprints.launchpad.net/nova/+spec/awesome-thing
+  should be named awesome-thing.rst
+
+* Please do not delete any of the sections in this template.  If you have
+  nothing to say for a whole section, just write: None
+
+* For help with syntax, see http://sphinx-doc.org/rest.html
+
+* To test out your formatting, build the docs using tox and see the generated
+  HTML file in doc/build/html/specs/<path_of_your_file>
+
+* If you would like to provide a diagram with your spec, ascii diagrams are
+  required.  http://asciiflow.com/ is a very nice tool to assist with making
+  ascii diagrams.  The reason for this is that the tool used to review specs is
+  based purely on plain text.  Plain text will allow review to proceed without
+  having to look at additional files which can not be viewed in gerrit.  It
+  will also allow inline feedback on the diagram itself.
+
+* If your specification proposes any changes to the Nova REST API such
+  as changing parameters which can be returned or accepted, or even
+  the semantics of what happens when a client calls into the API, then
+  you should add the APIImpact flag to the commit message. Specifications with
+  the APIImpact flag can be found with the following query:
+
+  https://review.openstack.org/#/q/status:open+project:openstack/nova-specs+message:apiimpact,n,z
+
+
+Problem description
+===================
+
+A detailed description of the problem. What problem is this blueprint
+addressing?
+
+Use Cases
+---------
+
+What use cases does this address? What impact on actors does this change have?
+Ensure you are clear about the actors in each use case: Developer, End User,
+Deployer etc.
+
+Proposed change
+===============
+
+Here is where you cover the change you propose to make in detail. How do you
+propose to solve this problem?
+
+If this is one part of a larger effort make it clear where this piece ends. In
+other words, what's the scope of this effort?
+
+At this point, if you would like to just get feedback on if the problem and
+proposed change fit in nova, you can stop here and post this for review to get
+preliminary feedback. If so please say:
+Posting to get preliminary feedback on the scope of this spec.
+
+Alternatives
+------------
+
+What other ways could we do this thing? Why aren't we using those? This doesn't
+have to be a full literature review, but it should demonstrate that thought has
+been put into why the proposed solution is an appropriate one.
+
+Data model impact
+-----------------
+
+Changes which require modifications to the data model often have a wider impact
+on the system.  The community often has strong opinions on how the data model
+should be evolved, from both a functional and performance perspective. It is
+therefore important to capture and gain agreement as early as possible on any
+proposed changes to the data model.
+
+Questions which need to be addressed by this section include:
+
+* What new data objects and/or database schema changes is this going to
+  require?
+
+* What database migrations will accompany this change.
+
+* How will the initial set of new data objects be generated, for example if you
+  need to take into account existing instances, or modify other existing data
+  describe how that will work.
+
+REST API impact
+---------------
+
+Each API method which is either added or changed should have the following
+
+* Specification for the method
+
+  * A description of what the method does suitable for use in
+    user documentation
+
+  * Method type (POST/PUT/GET/DELETE)
+
+  * Normal http response code(s)
+
+  * Expected error http response code(s)
+
+    * A description for each possible error code should be included
+      describing semantic errors which can cause it such as
+      inconsistent parameters supplied to the method, or when an
+      instance is not in an appropriate state for the request to
+      succeed. Errors caused by syntactic problems covered by the JSON
+      schema definition do not need to be included.
+
+  * URL for the resource
+
+    * URL should not include underscores, and use hyphens instead.
+
+  * Parameters which can be passed via the url
+
+  * JSON schema definition for the request body data if allowed
+
+    * Field names should use snake_case style, not CamelCase or MixedCase
+      style.
+
+  * JSON schema definition for the response body data if any
+
+    * Field names should use snake_case style, not CamelCase or MixedCase
+      style.
+
+* Example use case including typical API samples for both data supplied
+  by the caller and the response
+
+* Discuss any policy changes, and discuss what things a deployer needs to
+  think about when defining their policy.
+
+Example JSON schema definitions can be found in the Nova tree
+https://opendev.org/openstack/nova/src/branch/master/nova/api/openstack/compute/schemas
+
+Note that the schema should be defined as restrictively as
+possible. Parameters which are required should be marked as such and
+only under exceptional circumstances should additional parameters
+which are not defined in the schema be permitted (eg
+additionaProperties should be False).
+
+Reuse of existing predefined parameter types such as regexps for
+passwords and user defined names is highly encouraged.
+
+Security impact
+---------------
+
+Describe any potential security impact on the system.  Some of the items to
+consider include:
+
+* Does this change touch sensitive data such as tokens, keys, or user data?
+
+* Does this change alter the API in a way that may impact security, such as
+  a new way to access sensitive information or a new way to login?
+
+* Does this change involve cryptography or hashing?
+
+* Does this change require the use of sudo or any elevated privileges?
+
+* Does this change involve using or parsing user-provided data? This could
+  be directly at the API level or indirectly such as changes to a cache layer.
+
+* Can this change enable a resource exhaustion attack, such as allowing a
+  single API interaction to consume significant server resources? Some examples
+  of this include launching subprocesses for each connection, or entity
+  expansion attacks in XML.
+
+For more detailed guidance, please see the OpenStack Security Guidelines as
+a reference (https://wiki.openstack.org/wiki/Security/Guidelines).  These
+guidelines are a work in progress and are designed to help you identify
+security best practices.  For further information, feel free to reach out
+to the OpenStack Security Group at openstack-security@lists.openstack.org.
+
+Notifications impact
+--------------------
+
+Please specify any changes to notifications. Be that an extra notification,
+changes to an existing notification, or removing a notification.
+
+Consider proposing changes to the versioned notifications:
+
+* When the feature adds or removes fields to the API responses. For example
+  when the feature adds a new field to the ``GET /servers`` API response
+  consider adding similar information to the payload of the instance action
+  notifications
+* When the feature adds a new action to the existing API entities. For example
+  adding a new action to the server might mean you want to emit a corresponding
+  new instance action notification
+* When the feature adds a new resource (noun) to the REST API consider adding
+  new notifications about the creation and deletion of such resource
+
+Other end user impact
+---------------------
+
+Aside from the API, are there other ways a user will interact with this
+feature?
+
+* Does this change have an impact on python-novaclient and openstack client?
+  What does the user interface there look like?
+
+Performance Impact
+------------------
+
+Describe any potential performance impact on the system, for example
+how often will new code be called, and is there a major change to the calling
+pattern of existing code.
+
+Examples of things to consider here include:
+
+* A periodic task might look like a small addition but if it calls conductor or
+  another service the load is multiplied by the number of nodes in the system.
+
+* Scheduler filters get called once per host for every instance being created,
+  so any latency they introduce is linear with the size of the system.
+
+* A small change in a utility function or a commonly used decorator can have a
+  large impacts on performance.
+
+* Calls which result in a database queries (whether direct or via conductor)
+  can have a profound impact on performance when called in critical sections of
+  the code.
+
+* Will the change include any locking, and if so what considerations are there
+  on holding the lock?
+
+Other deployer impact
+---------------------
+
+Discuss things that will affect how you deploy and configure OpenStack
+that have not already been mentioned, such as:
+
+* What config options are being added? Should they be more generic than
+  proposed (for example a flag that other hypervisor drivers might want to
+  implement as well)? Are the default values ones which will work well in
+  real deployments?
+
+* Is this a change that takes immediate effect after its merged, or is it
+  something that has to be explicitly enabled?
+
+* If this change is a new binary, how would it be deployed?
+
+* Please state anything that those doing continuous deployment, or those
+  upgrading from the previous release, need to be aware of. Also describe
+  any plans to deprecate configuration values or features.  For example, if we
+  change the directory name that instances are stored in, how do we handle
+  instance directories created before the change landed?  Do we move them?  Do
+  we have a special case in the code? Do we assume that the operator will
+  recreate all the instances in their cloud?
+
+Developer impact
+----------------
+
+Discuss things that will affect other developers working on OpenStack,
+such as:
+
+* If the blueprint proposes a change to the driver API, discussion of how
+  other hypervisors would implement the feature is required.
+
+Upgrade impact
+--------------
+
+Describe any potential upgrade impact on the system, such as:
+
+* If this change adds a new feature to the compute host that the controller
+  services rely on, the controller services may need to check the minimum
+  compute service version in the deployment before using the new feature. For
+  example, in Ocata, the FilterScheduler did not use the Placement API until
+  all compute services were upgraded to at least Ocata.
+
+* While we strive to have feature parity between all virt drivers, it is not
+  uncommon for one virt driver to implement a new feature exposed out of the
+  API before the others. For example, extending the size of an attached
+  volume. Since Nova does not yet have any type of sophisticated *capabilities*
+  API so a user can know what actions can be performed on a given instance,
+  consider adding a new policy rule to at least let operators that cannot
+  support a virt-specific feature disable it in their cloud which is at least
+  presented to the user in an understandable way by getting a ``403 Forbidden``
+  error.
+
+* Nova supports N-1 version *nova-compute* services for rolling upgrades. Does
+  the proposed change need to consider older code running that may impact how
+  the new change functions, for example, by changing or overwriting global
+  state in the database? This is generally most problematic when making changes
+  that involve multiple compute hosts, like move operations such as migrate,
+  resize, unshelve and evacuate.
+
+
+Implementation
+==============
+
+Assignee(s)
+-----------
+
+Who is leading the writing of the code? Or is this a blueprint where you're
+throwing it out there to see who picks it up?
+
+If more than one person is working on the implementation, please designate the
+primary author and contact.
+
+Primary assignee:
+  <launchpad-id or None>
+
+Other contributors:
+  <launchpad-id or None>
+
+Feature Liaison
+---------------
+
+Ideally feature work is sponsored by a member of the `nova core team`_ or
+other experienced and active nova developer. The purpose of a liaison is
+to:
+
+* Mentor developers through the arcana of nova's development processes.
+* Advocate for (aka "care about") the feature to the rest of the nova team.
+* Be the initial go-to for reviews.
+
+See the :ref:`feature-liaisons` for more details.
+
+Feature liaison:
+  <name and/or nick>
+
+* Feature liaison is optional. However we suggest to find a liaison for
+  your feature as it will help getting your feature merged. The
+  :ref:`feature-liaisons` has details about how to find a liaison for your
+  work.
+* If you do not already have agreement from a nova developer to act as
+  your liaison, you may write "Liaison Needed" here and/or in your
+  commit message.
+* If you are a core or experienced nova dev, you need not have a
+  separate liaison; if you wish, you may just assign yourself, or put
+  "None"/"N/A".
+
+.. _`nova core team`: https://review.opendev.org/#/admin/groups/25,members
+
+Work Items
+----------
+
+Work items or tasks -- break the feature up into the things that need to be
+done to implement it. Those parts might end up being done by different people,
+but we're mostly trying to understand the timeline for implementation.
+
+Consider creating an ordering of patches, that allows gradually merging
+instead of the need to merge them all at once. For example if you are
+introducing a feature that requires implementation changes in multiple VM
+lifecycle operations then first add a step that rejects all the not yet
+supported actions with a HTTP 400 Bad Request. The error should explain that
+the <operation> is not supported with <feature> at this time. Then gradually
+remove the limitation as you progress with the implementation. This way we can
+merge your changes gradually and regardless when the feature freeze hit we can
+be sure that the system is consistent.
+
+Dependencies
+============
+
+* Include specific references to specs and/or blueprints in nova, or in other
+  projects, that this one either depends on or is related to.
+
+* If this requires functionality of another project that is not currently used
+  by Nova (such as the glance v2 API when we previously only required v1),
+  document that fact.
+
+* Does this feature require any new library dependencies or code otherwise not
+  included in OpenStack? Or does it depend on a specific version of library?
+
+
+Testing
+=======
+
+Please discuss the important scenarios needed to test here, as well as
+specific edge cases we should be ensuring work correctly. For each
+scenario please specify if this requires specialized hardware, a full
+openstack environment, or can be simulated inside the Nova tree.
+
+Please discuss how the change will be tested. We especially want to know what
+tempest tests will be added. It is assumed that unit test coverage will be
+added so that doesn't need to be mentioned explicitly, but discussion of why
+you think unit tests are sufficient and we don't need to add more tempest
+tests would need to be included.
+
+Is this untestable in gate given current limitations (specific hardware /
+software configurations available)? If so, are there mitigation plans (3rd
+party testing, gate enhancements, etc).
+
+If this is adding a new API microversion which alters a response schema, we
+will also need a corresponding change in Tempest to add the new schema under
+tempest/lib/api_schema/. This is required in order for the new microversion to
+be used in Tempest tests. Otherwise, new microversion requests will fail
+response schema validation in Tempest.
+
+
+Documentation Impact
+====================
+
+Which audiences are affected most by this change, and which documentation
+titles on docs.openstack.org should be updated because of this change? Don't
+repeat details discussed above, but reference them here in the context of
+documentation for multiple audiences. For example, the Operations Guide targets
+cloud operators, and the End User Guide would need to be updated if the change
+offers a new feature available through the CLI or dashboard. If a config option
+changes or is deprecated, note here that the documentation needs to be updated
+to reflect this specification's change.
+
+References
+==========
+
+Please add any useful references here. You are not required to have any
+reference. Moreover, this specification should still make sense when your
+references are unavailable. Examples of what you could include are:
+
+* Links to mailing list or IRC discussions
+
+* Links to notes from a summit session
+
+* Links to relevant research, if appropriate
+
+* Related specifications as appropriate (e.g.  if it's an EC2 thing, link the
+  EC2 docs)
+
+* Anything else you feel it is worthwhile to refer to
+
+
+History
+=======
+
+Optional section intended to be used each time the spec is updated to describe
+new design, API or any database schema updated. Useful to let reader understand
+what's happened along the time.
