ReleaseNotes/Bexar

Release Notes, Bexar

The Bexar release introduces large file support for OpenStack Object Storage (Swift), the OpenStack Image registry and Delivery service (Glance) and a lot of new features in OpenStack Compute (Nova).

<<TableOfContents()>>

New Features

OpenStack Object Storage (Swift)

• Large objects (greater than 5 GB) can now be downloaded using OpenStack Object Storage. While there is still a limit on the size of a single uploaded object, with this release the download size of a single object is virtually unlimited with the concept of segmentation. Refer to Managing Large Objects for more information.
• An experimental S3 compatibility middleware has been added to OpenStack Object Storage. This middleware intercepts S3 style requests and authorization, and transforms them into swift requests.
• Initial i18n support for logging messages.
• Swauth is a swift compatible authentication and authorization service implemented on top of swift as wsgi middleware. This will replace the dev_auth service in a future release.

OpenStack Compute (Nova)

• Support for raw disk images with libvirt and XenAPI hypervisors, without the complexity of a separate ramdisk or kernel image.
• IPv6 support. Refer to BexarIpv6supportReadme for information.
• Microsoft Hyper-V support. Refer to HypervInstall for information.
• Lots of new features have been added around the Openstack API, for example admin features to pause, suspend, lock and password reset instances.
• rescue-mode
• web-based-serial-console
• image-service-use-glance-clients
• hardware-staging
• diagnostics-per-instance
• bexar-iscsi-support-xenapi
• sheepdog-support
• db-versioning-and-migration
• bexar-xenapi-support-for-glance
• cow-instances
• ceph-block-driver
• Support for availability zones, through usage of a new scheduler: ZoneScheduler
• A DirectAPI, using introspection to exhibit features, is now available for developers to control Nova locally
• Some features that were partly implemented in the Austin release got finalized in Bexar: IP allocation was moved down the chain, project VPNs are supported and Nova now fully supports iptables-driven security groups.
• Finally, lots of efforts were spent unifying the code around common standards for i18n, logging, service handling (through eventlet), or using paste.deploy for the API nodes.

OpenStack Image Registry and Delivery service (Glance)

• Glance APIs (for registry and delivery) were unified, and a specific client class created
• Support for one-stop uploading a raw data images (through a POST to the Glance API)
• Glance can now store and fetch image data on a S3-like backend

Others

There were also deliveries outside those core projects during the Bexar development timeframe, in particular:

• The OpenStack Dashboard, a reference implementation of a web-based console for OpenStack Compute projects is now available. Refer to OpenStackDashboard for more information.
• A deployment tool for Nova
