PowerVM +admins can see benefits in their environments by making use of OpenStack. +This driver (along with a Neutron ML2 compatible agent and Ceilometer agent) +will provide capability for admins of PowerVM (which encapsulates PHYP and +Virtual I/O Servers) to use OpenStack natively. + + +Problem Description +=================== + +As a new ecosystem evolves around the POWER platform, there is not an +OpenStack driver that meets all of the needs for that ecosystem. The work +done here is to build a PowerVM driver in within the broader community. This +will sit alongside the existing libvirt driver utilized by PowerKVM +environments. + +This new driver must meet the following: + +* Built within the community + +* Fits the OpenStack model + +* Utilizes automated functional and unit tests + +* Enables use of PowerVM systems through the OpenStack APIs + +* Allows attachment of volumes from Cinder over supported protocols + + +The use cases should be the following: + +* As a deployer, all of the standard lifecycle operations (start, stop, +reboot, migrate, destroy, etc...) should be supported on a PowerVM based +instance. + +* As a deployer, I should be able to capture an instance to an image. + + +Proposed Change +=============== + +The changes proposed are the following: + +* Create a PowerVM based driver in a StackForge project. This will implement + the nova/virt/driver Compute Driver. + +* Provide deployments that work with the OpenStack model. + +* Driver will be implemented using a new version of the PowerVM REST API. + +* Ephemeral disks will be supported either with Virtual I/O Server (VIOS) + hosted local disks or via Shared Storage Pools (a PowerVM cluster file + system). + +* Volume support will be via Cinder through supported protocols for the + Hypervisor. + +* Network integration will be supported via a ML2 compatible Neutron Agent. + +* Automated Functional Testing will be provided to validate changes from the + broader OpenStack community against the PowerVM driver. + +* Thorough unit testing will be provided for the driver. + +The changes proposed will bring support for the PowerVM hypervisor into the +OpenStack ecosystem, following the OpenStack development model. + +This development is planned to be done in StackForge in a project named +‘powervm’. The intent is that the completion of this work will provide the +foundation to bring the PowerVM Nova driver (with supporting components) into +Nova Core via a separate BluePrint in the L release of OpenStack. + +Until the subsequent BluePrint is proposed for the L release, this driver is +to be considered experimental. + + +Data Model Impact +----------------- + +No data model impacts are anticipated as part of this work. + + +REST API Impact +--------------- + +The intent of this work item is to enable PowerVM to fit within the broader +OpenStack ecosystem, without requiring changes to the REST API. + +As such, no REST API impacts are anticipated. + + +Security Impact +--------------- + +The user may need to configure the credentials to communicate with the PowerVM +REST API via a CONF file. These should be encoded. + +New root wrap policies may need to be updated to support various commands for +the PowerVM REST API. + +No other security impacts are foreseen. + + +Notifications Impact +-------------------- + +No new notifications are anticipated. + + +Other End User Impact +--------------------- + +The administrator will notice new logging messages in the nova compute logs. + + +Performance Impact +------------------ + +It is a goal of the driver to deploy systems with the same speed and agility +as the libvirt driver within OpenStack. + +Since this process should match the OpenStack model, it is not planned to add +any new periodic tasks, database queries or other items. + +Performance impacts should be limited to the Compute Driver, as the changes +should be consolidated within the driver on the endpoint. The API processes +for instance should not be impacted. + + +Other Deployer Impact +--------------------- + +The cloud administrator will need to refer to documentation on how to +configure OpenStack for use with a PowerVM hypervisor. + +The existing configuration file attributes will be reused as much as possible. +This reduces the number of PowerVM specific items that will be needed. +However, the driver is likely to need some PowerVM specific options. + +In this case, we plan to keep the PowerVM specifics contained within the +configuration file (and driver code). Any new configuration options will have +the prefix "powervm_". + +There should be no impact to customers upgrading their cloud stack as this is +a genesis driver and should not have database impacts. + + +Developer Impact +---------------- + +The code for this driver will be contained within a powervm StackForge +project. The driver will be contained within /nova/virt/powervm/. The driver +will extend nova.virt.driver.ComputeDriver. + +The code will interact with PowerVM through an Open Sourced python binding +that is being defined. This python binding is a wrapper to the PowerVM REST +API. All operations to the hypervisor will go through the PowerVM REST API +via this binding. The driver will be maintained to support future revisions +of the PowerVM REST API as needed. + +For ephemeral disk support, either a Virtual I/O Server hosted local disk or a +Shared Storage Pool (a PowerVM clustered file system) will be supported. For +volume attachments, the driver will support Cinder based attachments via +protocols supported by the hypervisor. + +For networking, a blueprint is being proposed for the Neutron project that +will provide a Neutron ML2 Agent. This too will be developed in StackForge, +and a subsequent blueprint will be created to move to Neutron Core in the L +release of OpenStack. The Agent will provide the necessary configuration on +the Virtual I/O Server. The Nova driver code will have a +/nova/virt/powervm/vif.py file that will configure the network adapter on the +client VM. + +Automated functional testing will be provided through a third party continuous +integration system. It will monitor for incoming Nova change sets, run a set +of functional tests (lifecycle operations) against the incoming change, and +provide a non-gating vote (+1 or -1). + +Developers should not be impacted by these changes unless they wish to try the +driver. + +Until the driver is accepted into Nova core it will be considered experimental. + + +Community Impact +---------------- + +The intent of this blueprint is to bring another driver to OpenStack that +aligns with the ideals and vision of the community. + +It will be discussed in the Nova IRC and mailing lists. Representatives +working on this driver will be at the design summit, though no sessions are +planned on this topic. + + +Alternatives +------------ + +No alternatives appear viable to bring PowerVM support into the OpenStack +community. + + +Implementation +============== + +Assignee(s) +----------- + +Primary assignee: + kyleh + +Other contributors: + thorst + dwarcher + efried + +Work Items +---------- + +* Create a base PowerVM driver that is non-functional, but defines the methods + that need to be implemented. + +* Implement the host statistics methods (get_host_stats, get_host_ip_addr, + get_host_cpu_stats, get_host_uptime, etc.). + +* Implement the spawn method. + +* Implement the destroy method. + +* Implement the instance information methods (list_instances, instance_exists, + poll_rebooting_instances, etc.). + +* Implement the live migration methods. Note that, for ephemeral disks, this + will be specific to Shared Storage Pool environments where the Virtual I/O + Servers on the source and target systems share the same (clustered) file + system. + +* Implement support for Cinder volume operations. + +* Implement an option to configure an internal management NIC - used for + Resource Monitoring and Control (RMC) – as part of deploy. This is a + prerequisite for migration and resize. This will be controlled as part of + the CONF file. + +* Implement the network interface methods (attach_interface and + detach_interface). Delegate the Virtual I/O Server work to the + corresponding Neutron ML2 agent. + +* Implement an automated functional test server that listens for incoming + commits from the community and provides a non-gating vote (+1 or -1) on the + change. + + +Dependencies +============ + +* Will utilize the PowerVM REST API specification for management. Will + utilize future versions of this specification as it becomes available: + http://ibm.co/1lThV9R + +* Will build on top of a new open source python binding to previously noted + PowerVM REST API. This will be a prerequisite to utilizing the driver. + + +Testing +======= + +Tempest Tests +------------- + +Since the tempest tests should be implementation agnostic, the existing +tempest tests should be able to run against the PowerVM driver without issue. +This blueprint does not foresee any changes based off this driver. + +Thorough unit tests will be created within the Nova project to validate +specific functions within this driver implementation. + + +Functional Tests +---------------- + +A third party functional test environment will be created. It will monitor +for incoming nova change sets. Once it detects a new change set, it will +execute the existing lifecycle API tests. A non-gating vote (+1 or -1) will +be provided with information provided (logs) based on the result. + + +API Tests +--------- + +The REST APIs are not planned to change as part of this. Existing APIs should +be valid. All testing is planned within the functional testing system and via +unit tests. + + +Documentation Impact +==================== + +User Documentation +------------------ + +Documentation will be contributed which identifies how to configure the +driver. This will include configuring the dependencies specified above. + +Documentation will be done on wiki, specifically at a minimum to the following +page: http://docs.openstack.org/trunk/config-reference/content/ + section_compute-hypervisors.html + +Interlock will be done with the OpenStack documentation team. + + +Developer Documentation +----------------------- + +No developer documentation additions are anticipated. If the existing +developer documentation is updated to reflect more hypervisor specific items, +this driver will follow suit. + + +References +========== + +* PowerVM REST API Specification (may require newer versions as they + become available): http://ibm.co/1lThV9R + +* PowerVM Virtualization Introduction and Configuration: + http://www.redbooks.ibm.com/abstracts/sg247940.html + +* PowerVM Best Practices: http://www.redbooks.ibm.com/abstracts/sg248062.html diff --git a/nova-powervm/__init__.py b/nova-powervm/__init__.py new file mode 100644 index 00000000..2174afb3 --- /dev/null +++ b/nova-powervm/__init__.py @@ -0,0 +1,15 @@ +# Copyright 2014 IBM Corp. +# +# All Rights Reserved. +# +# Licensed under the Apache License, Version 2.0 (the "License"); you may +# not use this file except in compliance with the License.
