Snapshots and migrations were coded with a simplifying assumption that the maximum length of a VDI chain would be 3. Now that fast-cloning has been added, this assumption no longer holds. The goal of this patch is to remove the restriction for snapshots. A follow-on patch will remove the restriction for migrations. This patch changes the image-format for XenAPI images. Instead of naming the VHDs, 'base', 'image', and 'snap', they are now numbered staring with 0 as the leaf and going to N as the base-copy (root). Old-style images are still supported.

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 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 dicussion on the mailing list, at: https://lists.launchpad.net/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/ Changes to OpenStack Nova should be submitted for review via the Gerrit tool, following the workflow documented at: http://wiki.openstack.org/GerritWorkflow -- End of broadcast
