* As a beta release, EC support is nearly fully feature complete, but it is lacking support for some features (like multi-range reads) and has not had a full performance characterization. This feature relies on ssync for durability. Deployers are urged to do extensive testing and not deploy production data using an erasure code storage policy.
+
* В связи с beta релизом EC поддерживают практически полную функциональность, но отсутствует поддержка некоторых функций( например много-диапазонное чтение), а также функциональность не оптимизирована по производительности. Это зависит от использования ssync для долговечности. Мы предупреждаем о необходимости обширного тестирования и рекомендуем не использовать в продуктивных системах политик хранения erasure code.

==== API v2.1 ====
 
==== API v2.1 ====
  
* We have the first release of the next generation of the Nova API, v2.1. The v2.1 is designed to be backwards compatible with v2.0 with the addition of strong API validation. All changes to the API are discoverable via the advertised microversion. For more details see: http://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/api-microversions.html
+
* Вышел первый релиз следующего поколения Nova API, v2.1. Версия v2.1 поддерживает обратную совместимость с версией v2.0 с добавлением строгой валидации API. Все изменения в API можно увидеть средствами демонстрации микроверсий. Подробную информацию можно найти по ссылке: http://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/api-microversions.html
  
* For kilo, by default we are still using v2.0 API code to server v2.0 API requests. It is hoped that in liberty that v2.1 will be used to serve requests for both v2.0 and v2.1.
+
* Для релиза kilo по умолчанию используется код v2.0 API для обработки запросов v2.0 API. Планируется что в релизе liberty код версии v2.1 будет использоваться для обработки как запросов версии v2.0, так и версии v2.1.
  
* For liberty v2.0 is now frozen, and all new features will now be added into the v2.1 API using the microversions mechanismMicroversion increments released with kilo are:
+
* Для релиза liberty версия v2.0 заморожена
** Extending the keypair API to support for x509 certificates, to be used with Windows WinRM, is one of the first API features added as a microversion in the v2.1 API.
+
и все новые функции будут добавляться в  v2.1 API используя механизм микроверсийМикроверсии добавленные в релизе kilo:
** Exposing additional attributes in os-extended-server-attributes
+
** Расширение API ключевых пар для поддержки x509 сертификатов, для использования с Windows WinRM, это одна из первых API добавленных как микроверсия в v2.1 API.
 +
** Добавлены дополнительные аттрибуты в os-extended-server-attributes
  
* python-novaclient does not yet have support for the v2.1 API
+
* python-novaclient пока не содержит поддержки для v2.1 API
  
* The policy enforcement of Nova v2.1 API get improvement.
+
* Улучшено применение политик в Nova v2.1 API.
** Policy only enforce at the entry of API.
+
** Политика применяется только на входе в API.
** Without duplicated rules for single one API anymore.
+
** Правила для одного вызова больше не дублируются API.
** All the v2.1 API policy rule use 'os_compute_api' as prefix which distinguish with v2 API.
+
** Все правила политик v2.1 API используют прификс 'os_compute_api' который отличается от v2 API.
** Due to hard-code permission checks at db layer, part of Nova API isn't configurable by policy before. It's always required admin user. Part of Nova v2.1 API's hard-code permission checks is removed which make API policy configurable. The rest of hard-code permission checks will be removed at Liberty.
+
** В связи с проверками прав на уровне базы данных в коде, часть  Nova API прежде не имела возможности управления через политики. Эта часть всегда требовала прав администратора. Часть кода проверок в Nova v2.1 API's удалена, что дает API возможность конфигурации через политики. Оставшаяся часть будет удалена в релизе Liberty.

==== Поддержка обновления ====
  
* We have reduced the data migrations that happen in the DB migration scripts, this now happens in a "lazy" way inside the DB objects code. There are nova-manage commands to help force migration of the data. For more details see: http://specs.openstack.org/openstack/nova-specs/specs/kilo/approved/flavor-from-sysmeta-to-blob.html
+
* Мы уменьшили миграции данных в скриптах миграции БД, теперь они выполняются в "ленивом" подходе внутри кода объектов БД. Есть команды nova-manage для принудительного выполнения миграции данных. Подробная информаци может быть найдена по ссылке: http://specs.openstack.org/openstack/nova-specs/specs/kilo/approved/flavor-from-sysmeta-to-blob.html
  
 
* Change https://review.openstack.org/#/c/97946/ adds database migration 267 which scans for null instances.uuid records and will fail if any are found since the migrate ultimately needs to make instances.uuid non-nullable and adds a UniqueConstraint on that column.  A helper script is provided to search for null instances.uuid records before running the database migrations.  Before running 'nova-manage db sync', run the helper script 'nova-manage db null_instance_uuid_scan' which, by default, will just search and dump results, it does not change anything.  Pass the --delete option to the null_instance_uuid_scan command to automatically remove any null records were instances.uuid is null.

* Evacuate recovery code has the potential to destroy data. On nova-compute startup, instances reported by the hypervisor are examined to see if they have moved (i.e. been evacuated) from the current host during the outage. If the determination is made that they were, then they are destroyed locally. This has the potential to choose incorrectly and destroy instances unexpectedly. On libvirt-like nodes, this can be triggered by changing the system hostname. On vmware-like nodes, this can be triggered by attempting to manage a single vcenter deployment from two different hosts (with different hostnames). This will be fixed properly in Liberty, but for now deployments that wish to disable this behavior as a preventive measure can set workarounds.destroy_after_evacuate=False. NOTE: This is not a regression and has been a flaw in the design of the evacuate feature since its introduction. There is no easy fix for this, hence this workaround to limit the potential for damage. The proposed fix in liberty is here: https://review.openstack.org/#/c/161444/.

Замечания к релизу OpenStack 2015.1.0 (Kilo)

Релиз OpenStack Kilo посвящен памяти Chris Yeoh, который оставил свою семью и нас слишком рано.

Объектное хранилище OpenStack (Swift)

Новые ключевые функции

Erasure Code (beta)

Swift теперь поддерживает тип политики хранения erasure-code (EC). Это позволит достигнуть при установке очень высокой долговечности с меньшей физической емкостью по сравнению с хранилищем с репликацией. Однако EC использует больше ресурсов CPU и сети, что возможно не является лучшим решением для любого варианта использования. EC хорошо подходит для хранения больших объемов данных, с нечастым доступом в одном регионе.

Реализация erasure codes в Swift прозрачна для конечных пользователей. В API нет различий между реплицируемым и EC хранилищем.

Для поддержки erasure codes в Swift появилась зависимость от библиотек PyECLib и liberasurecode. liberasurecode это подключаемая библиотека которая позволяет реализовать актуальные алгоритмы EC в библиотеке по вашему выбору.

Полная документация доступна по адресу http://swift.openstack.org/overview_erasure_code.html

Композитные токены

Композитные токены позволяют другим службам OpenStack services сохранять данные в Swift от имени клиента так что ни служба ни клиент не могут обновить данные без согласия обеих сторон.

Пример: пользователь запрашивает Nova сохранить снимок виртуальной машины. Nova отправляет запрос в Glance, Glance записывает образ в Swift контейнер как множество объектов. В этом случае пользователь не сможет модифицировать снимок без наличия действующего токена службы. Также и служба не сможет обновить данные без действующего токена пользователя. При это м данные будут храниться в пользовательском аккаунте Swift, что делает учет проще.

Полная документация доступна по адресу http://swift.openstack.org/overview_backing_store.html

Обновления размещения данных для небольших небаласируемых кластеров

Размещение данных в Swift сейчас это вес аккаунтов для устройств. Это позволяет операторам поэтапно добавлять новые зоны и регионы без немедленного перемещения больших объемов данных. Также, если кластер не сбалансирован ( например двух зонный кластер где одна зона имеет вдвое больше ресурсов чем другая), Swift будет более эффективно использовать доступное пространство и реагировать когда реплики размещены без достаточной дисперсии в кластере.

Улучшения глобальной репликации кластера

Репликация между регионами теперь будет перемещать только одну реплику за цикл репликации. Это даст возможность удаленному региону проводить внутреннюю репликацию и уменьшить количество перемещаемых через WAN данных

Известные проблемы

  • В связи с beta релизом EC поддерживают практически полную функциональность, но отсутствует поддержка некоторых функций( например много-диапазонное чтение), а также функциональность не оптимизирована по производительности. Это зависит от использования ssync для долговечности. Мы предупреждаем о необходимости обширного тестирования и рекомендуем не использовать в продуктивных системах политик хранения erasure code.

Замечания по обновлению

Как и всегда вы можете обновлять систему до текущей версии Swift без остановки обслуживания конечных пользователей.

  • Для поддержки erasure codes в Swift имеются новые зависимости от PyECLib (и транзитивно liberasurecode). Также минимальная требуемая версия библиотеки eventlet повышена.

API v2.1

  • Вышел первый релиз следующего поколения Nova API, v2.1. Версия v2.1 поддерживает обратную совместимость с версией v2.0 с добавлением строгой валидации API. Все изменения в API можно увидеть средствами демонстрации микроверсий.

  • Для релиза liberty версия v2.0 заморожена

и все новые функции будут добавляться в v2.1 API используя механизм микроверсий. Микроверсии добавленные в релизе kilo:

    • Расширение API ключевых пар для поддержки x509 сертификатов, для использования с Windows WinRM, это одна из первых API добавленных как микроверсия в v2.1 API.
    • Добавлены дополнительные аттрибуты в os-extended-server-attributes
  • python-novaclient пока не содержит поддержки для v2.1 API
  • Улучшено применение политик в Nova v2.1 API.
    • Политика применяется только на входе в API.
    • Правила для одного вызова больше не дублируются API.
    • Все правила политик v2.1 API используют прификс 'os_compute_api' который отличается от v2 API.

Поддержка обновления

  • Мы уменьшили миграции данных в скриптах миграции БД, теперь они выполняются в "ленивом" подходе внутри кода объектов БД. Есть команды nova-manage для принудительного выполнения миграции данных. Подробная информаци может быть найдена по ссылке: http://specs.openstack.org/openstack/nova-specs/specs/kilo/approved/flavor-from-sysmeta-to-blob.html

  • A selection of performance optimisations
  • We are in the process of making structural changes to the scheduler that will help improve our ability to evolve and improve scheduling. This should not be visible from an end user perspective.

Cells v2

  • There are some initial parts of cell v2 supported added, but this feature is not yet ready to use.
  • new 'nova-manage api_db sync' and 'nova-manage api_db version' commands for working with the new api database for cells, but nothing is using this database yet so it is not necessary to set it up.

Замечания по обновлениям

Below are changes you should be aware of when upgrading. Where possible, The git commit hash is provided for you to find more information:

  • Neutron ports are no longer deleted after your server is deleted, if you created them outside of Nova: 1153a46738fc3ffff98a1df9d94b5a55fdd58777
  • EC2 API support has been deprecated, and is likely to be removed in kilo, see f098398a836e3671c49bb884b4a1a1988053f4b2
  • Websocket proxies need to be upgraded in a lockstep with the API nodes, as older API nodes will not be sending the access_url when authorizing console access, and newer proxy services (this commit and onward) would fail to authorize such requests 9621ccaf05900009d67cdadeb1aac27368114a61
  • After fully upgrading to kilo (i.e. all nodes are running kilo code), you should start a background migration of flavor information from its old home to its new home. Kilo conductor nodes will do this on the fly when necessary, but the rest of the idle data needs to be migrated in the the background. This is critical to complete before the Liberty release, where support for the old location will be dropped. Use "nova-manage migrate-flavor-data" to perform this transition.
  • Due to the improvement on Nova v2.1 API policy enforcement. There are a lot of change happened to v2.1 API policy. Because v2.1 API didn't released before, those change won't keep back-compatible. It is better to use policy sample configuration instead of old one.
  • VMware rescue VM behaviour no longer creates a new VM and instead happens in place: cd1765459a24e52e1b933c8e05517fed75ac9d41
  • force_config_drive = always has been deprecated, and force_config_drive = True should be used instead: c12a78b35dc910fa97df888960ef2b9a64557254
  • Running hyper-v, if you deployed code that was past this commit: b4d57ab65836460d0d9cb8889ec2e6c3986c0a9b but before this commit: c8e9f8e71de64273f10498c5ad959634bfe79975 you make have problems to manually resolve see: c8e9f8e71de64273f10498c5ad959634bfe79975
  • Changed the default value of: multi_instance_display_name_template see: 609b2df339785bff9e30a9d67d5c853562ae3344
  • Please use "nova-manage db null_instance_uuid_scan" to ensure the DB migrations will apply cleanly, see: c0ea53ce353684b48303fc59393930c3fa5ade58

OpenStack Dashboard (Horizon)

Key New Features

  • Support for Federated authentication via Web Single-Sign-On -- When configured in keystone, the user will be able to choose the authentication mechanism to use from those support by the deployment. This feature must be enabled by changes to local_settings.py to be utilized. The related settings to enable and configure can be found here.
  • Support for Theming -- A simpler mechanism to specify a custom theme for Horizon has been included. Allowing for use of CSS values for Bootstrap and Horizon variables, as well as the inclusion of custom CSS. More details available here.
  • Sahara UX Improvements -- Dramatic improvements to the Sahara user experience have been made with the addition of guided cluster creation and guided job creation pages.
  • Launch Instance Wizard (beta) -- A full replacement for the launch instance workflow has been implemented in AngularJS to address usability issues in the existing launch instance workflow. Due to the late inclusion date and limited testing, this feature is marked as beta for Kilo and not enabled by default. To use the new workflow, the following change to local_settings.py is required: LAUNCH_INSTANCE_NG_ENABLED = True. Additionally, you can disable the default launch instance wizard with the following: LAUNCH_INSTANCE_LEGACY_ENABLED = False. This new work is a view into future development in Horizon.

Upgrade Notes

  • Django 1.7 is now supported.


OpenStack Identity (Keystone)

Key New Features

Hierarchical multitenancy

Projects can be nested under other projects by setting the parent_id attribute to an existing project when creating a new project. You can also discovery the parent-child hierarchy through the existing /v3/projects API.

Role assignments can now be assigned to both users and groups on subtrees in the project hierarchy.

This feature will require corresponding support across other OpenStack services (such as hierarchical quotas) in order to become broadly useful.

Fernet tokens

Unlike UUID tokens which must be persisted to a database, Fernet tokens are entirely non-persistent. Deployers can enable the Fernet token provider using [token] provider = keystone.token.providers.fernet.Provider in keystone.conf.

Fernet tokens require symmetric encryption keys which can be established using keystone-manage fernet_setup and periodically rotated using keystone-manage fernet_rotate. These keys must be shared by all Keystone nodes in a multi-node (or multi-region) deployment, such that tokens generated by one node can be immediately validated against another.

Identity federation

  • Keystone can now act as a federated identity provider (IdP) for another instance of Keystone by issuing SAML assertions for local users, which may be ECP-wrapped.
  • Added support for OpenID Connect as a federated identity authentication mechanism.
  • Added the ability to associate many "Remote IDs" to a single identity provider in Keystone. This will help in a case where many identity providers use a common mapping.
  • Added the ability for a user to authenticate via a web browser with an existing IdP, through a Single Sign-On page.
  • Federated tokens now use the token authentication method, although both mapped and saml2 remain available.
  • Federated users may now be mapped to existing local identities.
  • Groups specified in the mapping rulesets can be identified by name and domain.
  • Groups appearing in federated identity assertions may now be automatically mapped as locally existing groups with local user membership mappings (filtered by white and blacklists).

LDAP

  • Filter parameters specified by API users are now processed by LDAP itself, instead of by Keystone.
  • Experimental support was added to store domain-specific identity backend configuration in SQL using the HTTP API. The primary use case for this is to create a new domain with the HTTP API, and then immediately configure a domain-specific LDAP driver for it without restarting Keystone.

Authorization

  • The "assignment" backend has been split into a "resource" backend (containing domains, projects, and roles) and an "assignment" backend, containing the authorization mapping model.
  • Added support for trust redelegation. If allowed when the trust is initially created, a trustee can redelegate the roles from the trust via another trust.
  • Added support for explicitly requesting an unscoped token from Keystone, even if the user has a default_project_id attribute set.
  • Deployers may now opt into disallowing the re-scoping of scoped tokens by setting [token] allow_rescope_scoped_token = false in keystone.conf.


Upgrade Notes

  • XML support in Keystone has been removed as of Kilo. When upgrading from Juno to Kilo, it is recommended that references to XML and XmlBodyMiddleware be removed from the Keystone Paste configuration. This includes removing the XML middleware filters and the references from the public_api, admin_api, api_v3, public_version_api, admin_version_api and any other pipelines that may contain the XML filters.
  • All previous extensions (OS-FEDERATION, OS-OAUTH1, OS-ENDPOINT-POLICY and OS-EP-FILTER) are now enabled by default, and are correspondingly marked as either "experimental" or "stable".
  • SQL Schema Downgrades are no longer supported. This change is the result of evaluation that downward SQL migrations are not well tested and become increasingly difficult to support with the volume of data-change that occurs in many of the migrations.
  • The following python libraries are now required: cryptography, msgpack-python, pysaml2 and oauthlib.
  • keystone.middleware.RequestBodySizeLimiter is now deprecated in favor of oslo_middleware.sizelimit.RequestBodySizeLimiter and will be removed in Liberty.
  • Eventlet-specific configuration options such as public_bind_host, bind_host, admin_bind_host, admin_port, public_port, public_workers, admin_workers, tcp_keepalive, tcp_keepidle have been moved from the [DEFAULT] configuration section to a new configuration section called [eventlet_server]. Similarly, Eventlet-specific SSL configuration options such as enable, certfile, keyfile, ca_certs, cert_required have been moved from the [ssl] configuration section to a new configuration section called [eventlet_server_ssl].
  • keystone.token.backends.sql has been removed in favor of keystone.token.persistence.backends.sql.
  • keystone.token.backends.kvs has been removed in favor of keystone.token.persistence.backends.kvs.
  • keystone.token.backends.memcache has been removed in favor of keystone.token.persistence.backends.memcache.
  • keystone.assignment.backends.kvs has been removed in favor of keystone.assignment.backends.sql.
  • keystone.identity.backends.kvs has been removed in favor of keystone.identity.backends.sql.
  • keystone.contrib.stats.core.StatsMiddleware has been removed in favor of external tooling.
  • keystone.catalog.backends.templated.TemplatedCatalog has been removed in favor of keystone.catalog.backends.templated.Catalog.
  • keystone.contrib.access.core.AccessLogMiddleware has been removed in favor of external access logging.
  • keystone.trust.backends.kvs has been removed in favor of keystone.trust.backends.sql.
  • [catalog] endpoint_substitution_whitelist has been removed from keystone.conf as part of a related security hardening effort.
  • [signing] token_format has been removed from keystone.conf in favor of [token] provider.

OpenStack Network Service (Neutron)

Key New Features

  • Subnet allocation feature allows creating subnets from a pre-defined pool of addresses instead of providing explicit addresses.
    • Support in python-neutron-client (subnetpool-create/update/list/show/delete and subnet-create --subnetpool).
    • API documentation work is underway.
    • Horizon support is tracked with neutron-subnet-allocation blueprint.
  • DVR now supports VLANs in addition to VXLAN/GRE
  • ML2 Hierarchical Port Binding
  • New LBaaS Version 2 API
  • Portsecurity support for the OVS ML2 Driver
  • Multiple Prefixes for IPv6 (tenant guest interfaces can now get multiple IPv6 addresses)
  • IPv6 Router (allows guests to get global IPv6 addresses and talk to the world, without NAT)
  • API extension for MTU Selection and Advertisement
  • API extension to check for support of VLAN trunking networks for NFV
  • New Plugins supported in Kilo include the following:
    • A10 Networks LBaaS V2 Driver
    • Brocade LBaaS V2 Driver
    • Brocade ML2 driver for MLX and ICX switches
    • Brocade L3 routing plugin for MLX switch
    • Brocade Vyatta vRouter L3 Plugin
    • Brocade Vyatta vRouter Firewall Driver
    • Brocade Vyatta vRouter VPN Driver
    • Cisco CSR VPNaaS Driver
    • Dragonflow SDN based Distributed Virtual Router L3 Plugin
    • Freescale FWaaS Driver
    • Intel Mcafee NGFW FWaaS Driver
    • IPSEC Strongswan VPNaaS Driver

Known Issues

  • The Firewall-as-a-Service project is still marked as experimental for the Kilo release.
  • Bug 1438819
    • When a new subnet is created on an external network, all existing routers with gateways on the network will get a new address allocated from it. For IPv4 networks, this could consume the entire subnet for router gateway ports.

Upgrade Notes

From Havana, Neutron no longer supported an explicit lease database (https://bugs.launchpad.net/bugs/1202392). This left dead code including unused environment variable. In order to remove the dead code (https://review.openstack.org/#/c/152398/), a change to the dhcp.filter is required, so that line:

dnsmasq: EnvFilter, dnsmasq, root, NEUTRON_NETWORK_ID=

Be replaced by:

dnsmasq: CommandFilter, dnsmasq, root

After advanced services were split into separate packages and received their own service configuration files (specifically, etc/neutron/neutron_lbaas.conf, etc/neutron/neutron_fwaas.conf and etc/neutron/neutron_vpnaas.conf), active service provider configuration can be different after upgrade (specifically, default load balancer (haproxy) and vpn (openswan) providers can be enabled for you even though you previously disabled them in neutron.conf). Please make sure you review configuration after upgrade so that it reflects the desired state of service providers.

Note: this will have no effect if the related service plugin is not loaded in neutron.conf.


Other Notes (Deprecation/EOL etc)

  • Deprecation
    • Brocade Monolithic plugin for Brocade's VDX/VCS series of hardware switches will be deprecated in the L-Release. The functionality provided by this plugin is now addressed by the ML2 Driver available for the VDX series of hardware. The plugin is slated for removal after this release cycle.
    • The monolithic Cisco Meta plugin for Nexus1000V will be deprecated in the L-Release. The functionality provided by this plugin is now available with the Cisco Nexus1000V ML2 mechanism driver. The monolithic plugin is slated for removal after this release cycle.

OpenStack Block Storage (Cinder)

Key New Features

  • From this point forward any new database schema upgrades will not require restarting Cinder services right away. The services are now independent of schema upgrades. This is part one to Cinder supporting rolling upgrades!
  • Ability to add/remove volumes from an existing consistency group. Read docs for more info.
  • Ability to create a consistency group from an existing consistency group snapshot. Read docs for more info.
  • Create more fine tuned filters/weighers to set how the scheduler will choose a volume backend. Read the docs for more info.
  • Encrypted volumes can now be backed up using the Cinder backup service. Read the docs for more info.
  • Ability to create private volume types. This is perfect when you want to make volume types available to only a specific tenant or to test it before making available to your cloud. To do so use the cinder type-create <name> --is-public.
  • Oversubscription with thin provision is configurable. Read docs for more info.
  • Ability to add descriptions to volume types. To do so use cinder type-create <name> <description>
  • Cinder now can return multiple iSCSI paths information so that the connector can attach volumes even when the primary path is down (when connector's multipath feature is enabled or not enabled).
  • Add ability to specify a local lvm.conf file. When using the LVM driver this option allows you to set a Cinder specific lvm.conf file in /etc/cinder/lvm.conf. This enables specific LVM settings and filters that are only picked up and used by Cinder.
  • The Cinder backup service can now backup to an NFS exported filesystem. Read the docs for more info.

Upgrade Notes

  • The 'host' config option for multiple-storage backends in cinder.conf is renamed to 'backend_host' in order to avoid a naming conflict with the 'host' to locate redis. If you use this option, please ensure your configuration files are updated.


OpenStack Telemetry (Ceilometer)

Key New Features

  • Support to add jitter to polling cycles to ensure pollsters are not querying service's api at the same time

    • Telemetry now supports to collect and store all the event type meters as events. A new option, disable_non_metric_meters, was added to the configuration in order to provide the possibility to turn off storing these events as samples. For further information please see the Telemetry Configuration Reference
    • The Administrator Guide in OpenStack Manuals was updated with a new Events section, where you can find further information about this functionality.
  • Improved pipeline publishing support:
    • Support to publish events and samples to Kafka or HTTP targets
    • Publish data to multiple queues

  • Gnocchi dispatch support for ceilometer-collector
  • Self-disabled pollster mechanism


Upgrade Notes

  • Deprecated meters:
    • The instance:<flavor> meter is deprecated in the Kilo release. In order to retrieve samples or statistics based on flavor you can use the following queries:
  statistics:
  ceilometer statistics -m instance -g resource_metadata.instance_type
  samples:
  ceilometer sample-list -m instance -q metadata.instance_type=<value>


OpenStack Orchestration (Heat)

Key New Features

Upgrade Notes

  • The default of the configuration option "num_engine_workers" has changed from 1 to a number based on the the number of CPUs. This is now the same as the way other projects set the number of workers.
  • The default for the configuration option "max_nested_stack_depth" has been increased to 5.
  • There is a new configuration option "convergence" it is by default off. This feature is not yet complete and this option should remain off.
  • In preparation of an upcoming major feature (convergence) there have been some significant DB schema changes. It is suggested that the heat-engine is shutdown during schema upgrades.

Other Notes (Deprecation/EOL etc)

Deprecation

  • The follow resources are deprecated OS::Heat::HARestarter and OS::Heat::CWLiteAlarm
  • The CloudWatch API (heat-api-cw)


OpenStack Database service (Trove)

Key New Features

  • Support for a new replication strategy based on async GTID replication (new in MySQL 5.6)
    • We now support for creating n-replicas from a single master in one API call
    • We also support for failover from an unresponsive master to the most up-to-date slave can now be achieved using the new 'eject-master' API
  • Support for Trove guest managers to support the following new datastores:
    • Vertica, and Vertica Cluster
    • DB2
    • CouchDB

  • Sahara now requires policy.json configuration file.


OpenStack Bare Metal service (Ironic)

Key New Features

State Machine

Ironic now uses a formal model for the logical state of each node it manages (New Ironic State Machine). This has enabled the addition of two new processes: cleaning and inspection.

  • Automatic disk erasure between tenants is now enabled by default. This may be extended to perform additional cleaning steps, such as re-applying firmware, resetting BIOS settings, etc (Node Cleaning).
  • Both in-band and out-of-band methods are available to inspect hardware. These methods may be used to update Node properties automatically (Hardware Inspection).

Version Headers

The Ironic REST API expects a new X-OpenStack-Ironic-API-Version header be passed with each HTTP[S] request. This header allows client and server to negotiate a mutually supported interface (REST API "micro" versions). In the absence of this header, the REST service will default to a compatibility mode and yield responses compatible with Juno clients. This mode, however, prevents access to most features introduced in Kilo.

Hardware Driver Changes

The following new drivers were added:


The following enhancements were made to existing drivers:


Support for third-party and out-of-tree drivers is enhanced by the following two changes:

  • Drivers may store their own "internal" information about Nodes.
  • Drivers may register their own periodic tasks to be run by the Conductor.
  • vendor_passthru methods now support additional HTTP methods (eg, PUT and POST).
  • vendor_passthru methods are now discoverable in the REST API. See node vendor passthru and driver vendor passthru

Other Changes

  • Logical names may be used to address Nodes, in addition to their canonical UUID.
  • For servers with varied local disks, hints may be supplied that affect which disk device the OS is provisioned to.
  • Support for fetching kernel, ramdisk, and instance images from HTTP[S] sources directly has been added to remove the dependency on Glance. Using ironic as a standalone service
  • Nodes may be placed into maintenance mode via REST API calls. An optional maintenance reason may be specified when doing so.

Known Issues

  • Running more than one nova-compute process is not officially supported.
    • While Ironic does include a ClusteredComputeManager, which allows running more than one nova-compute process with Ironic, it should be considered experimental and has many known problems.
  • Drivers using the "agent" deploy mechanism do not support "rebuild --preserve-ephemeral"

Upgrade Notes

  • IPMI Passwords are now obfuscated in REST API responses. This may be disabled by changing API policy settings.
  • The "agent" class of drivers now support both whole-disk and partition based images.
  • The driver_info parameters of "pxe_deploy_kernel" and "pxe_deploy_ramdisk" are deprecated in favour of "deploy_kernel" and "deploy_ramdisk".
  • Drivers implementing their own version of the vendor_passthru() method has been deprecated in favour of the new @passthru decorator.

Juno to Kilo

The recommended upgrade process is documented here:

Upgrading from Icehouse "nova-baremetal"

An upgrade from an Icehouse Nova installation using the "baremetal" driver directly to Kilo Ironic is untested and unsupported. Instead, please follow the following upgrade path:

  1. Icehouse Nova "baremetal" -> Juno Nova "baremetal"
  2. Juno Nova "baremetal" -> Juno Ironic
  3. Juno Ironic -> Kilo Ironic

Documentation for steps 1 and 2 is available at: https://wiki.openstack.org/wiki/Ironic/NovaBaremetalIronicMigration
