This allows Cinder to call swap_volume as part of a volume migration. Cinder creates the new volume and calls Nova to perform the swap. When Nova finishes, it calls Cinder to complete the migration, where it updates the volume metadata so that the volume ID remains unchanged. Thus, if Cinder detects that the migration was initiated by Cinder, it will return the original volume ID to keep using. Otherwise, it will return the new volume's ID for Nova to use, which is what it had done before. Change-Id: If352f2e11701148a5aeccaf7fd6379528fa8be31
OpenStack Nova README ===================== OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of virtualization technologies, including KVM, Xen, LXC, VMware, and more. In addition to its native API, it includes compatibility with the commonly encountered Amazon EC2 and S3 APIs. OpenStack Nova is distributed under the terms of the Apache License, Version 2.0. The full terms and conditions of this license are detailed in the LICENSE file. Nova primarily consists of a set of Python daemons, though it requires and integrates with a number of native system components for databases, messaging and virtualization capabilities. To keep updated with new developments in the OpenStack project follow `@openstack <http://twitter.com/openstack>`_ on Twitter. To learn how to deploy OpenStack Nova, consult the documentation available online at: http://docs.openstack.org For information about the different compute (hypervisor) drivers supported by Nova, read this page on the wiki: https://wiki.openstack.org/wiki/HypervisorSupportMatrix In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at: http://bugs.launchpad.net/nova Developers wishing to work on the OpenStack Nova project should always base their work on the latest Nova code, available from the master GIT repository at: http://github.com/openstack/nova Developers should also join the discussion on the mailing list, at: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests. Further developer focused documentation is available at: http://nova.openstack.org/ For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst file. -- End of broadcast
