Release Notes, Austin

The Austin release is the first OpenStack release which combines the Swift and Nova projects.

What's New in OpenStack

These sections contain what we expect will be implemented in time for the October 21 release, but be aware that these notes may change up to release time.

Rescue Mode

Allow users to fix file system and configuration errors by following these basic steps: shutting down the VM and then creating new a VM with a rescue image with a random password as primary and customer VM disk as secondary image. This is just a new slice, with the old disk attached.

Redis Optional

The prerequisites for OpenStack Compute have changed so that it's optional to use Redis the key-value pair store for authentication.

OpenStack Clients

The OpenStack Web Control Panel is available as a preview. It is a web application to manage OpenStack compute and storage and currently offers a user login and cloud server management only. Prerequisites for using the web application are having Ruby and the Sinatra Ruby gem installed.

Xen Hypervisor Support

In addition to KVM, user-mode-linux and Xen Server, Nova supports Xen classic in the Austin release by adding a libvirt domain xml template with a "xen" option as well as using the Xen API, however, the Xen API implementation is not completely finished.

Security Groups Implementation

EC2 and Eucalyptus API's both contain a firewalling concept known as security groups. People migrating from EC2 (or Eucalyptus) may be using security groups as part of their security model. To use this feature, look for a filter in libvirt for each security group. Once the last instance owned by a given user is removed from a node, the filter is undefined (removed).

Image File Management (Partial Implementation)

Implement a VM image registry service with a project known as Glance. The clients are called Parallax, with an API used for looking up and finding images, with a complementary client known as Teller as the fetch mechanism to get the images from the registry. Learn more about the implementation by reading the GlanceAPISpec.

Known Limits

IPv6 is not yet implemented in this release.

Hyper-V is not yet fully implemented but code is started.

OpenStack Object Store supports objects smaller than 5 GB.
