=============================================== Kilo Series (2015.1.0 - 2015.1.4) Release Notes =============================================== 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: * AMT * iRMC * VirtualBox (testing driver only) The following enhancements were made to existing drivers: * Configdrives may be used with the "agent" drivers in lieu of a metadata service, if desired. * SeaMicro driver supports serial console * iLO driver supports UEFI secure boot * iLO driver supports out-of-band node inspection * iLO driver supports resetting ilo and bios during cleaning 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.
