This is a minor release that fixes a few bugs. Specifically, it updates junixsocket to 1.14. A Java security update necessitated this change. The qcow2 support is also more resilient to hanging qemu_nbd processes.

Users should note that this release will ONLY work with Java 1.6.0 Update 41 and later, which they are strongly encouraged to upgrade to. If for some reason upgrading is impossible, Nimbus Infrastructure 2.10 should continue to work on that release.

Check out the changelog for full details.

We would like to particularly acknowledge the contributions to this release of our partners in the open source community: Michael Paterson and Adam Brust. The features in this release were supported by the Ocean Observatory Initiative and FutureGrid projects.

The Nimbus 2.10.1 release is available on the downloads page.

Documentation (still in progress) is available at: http://www.nimbusproject.org/docs/2.10.1/

This release primarily offers more customization options to the user: it provides support for custom SSH options, provides customization and management features for the working directory on the deployed VMs, allows users to customize timeouts, and run local commands from cloudinit.d launch plans. In addition, we expanded and clarified the documentation as well as fixed bugs.

The latest documentation for cloudinit.d can be found at: http://www.nimbusproject.org/doc/cloudinitd/latest/

Happy upgrades!

Join us for a cloud computing tutorial at SC12 on Monday, November 12, starting from 8:30 AM, to learn about why scientific applications are increasingly drifting towards clouds, the fundamentals of the approach, and find out how your research group can leverage this new development.

You will get the chance to interact with real production clouds and launch your own virtual machines and applications, and also discover open challenges of cloud computing for science.

More details are available on the SC12 schedule.

Update: the slides are now available online.]]> 2012-10-30T18:12:31+00:00 http://www.nimbusproject.org/news/#327 http://www.nimbusproject.org/news/nimbus_infrastructure_2.10_final_release/#When:17:41:06Z Happy Nimbus Infrastructure 2.10 final release!

The main addition in the 2.10 release is support for copy-on-write based on the qcow2 format; when used in coordination with the image cache, this feature decreases the time needed to start virtual machines. It is now also possible to set the networks associated with an instance type in the same way CPU and memory are set and to select a kernel using the EC2 interface.

In addition, the release also includes bugfixes and additions to documentation. Check out the changelog for full details.

We would like to particularly acknowledge the contributions to this release of our partners in the open source community: Michael Paterson, Hsin Shao, Brett Wu, and Feng Zheng. The features in this release were supported by the Ocean Observatory Initiative and FutureGrid projects.

It is now also possible to set the networks associated with an instance type in the same way CPU and memory are set and to select a kernel using the EC2 interface. The main changes from RC1 are functionalities for administrators to clean up corrupted instances from the service, as well as the usual set of bug fixes.

In addition, the release also includes bugfixes and additions to documentation. Check out the changelog for full details.

Some of the effort for this release came from our open source community. We would like to particularly acknowledge the contributions of Michael Paterson, Hsin Shao, Brett Wu, and Feng Zheng. The features in this release were supported by the Ocean Observatory Initiative and FutureGrid projects.

The Nimbus 2.10 RC2 is available on the downloads page.

Documentation (still in progress) is available at: http://www.nimbusproject.org/docs/2.10/

We appreciate help from all who are willing to test this release. To help provide an easy vehicle for feedback and resolve issues quickly we offer real-time access to a Nimbus RC chatroom for serious alpha testers. If you would like to participate, please contact us for access.

Everybody have a great Labor Day weekend!

Along with some minor improvements and bug fixes the major contributions of this release are:

• Users can now associate meta data describing a virtual machine image along side of their image in the Cumulus repository.
• Users can query the cloud for detailed information about the hardware on which their VM is running. Determining the specific location of VMs has enabled FutureGrid researchers to study scientific computation in infrastructure clouds. In order to use this feature the infrastructure cloud administrator must enable it.

The new release can be found on the Nimbus downloads page.

The major additions in this release are support for Availability Zones, configurable EC2 multi-core instances, more robust support for LANTorrent and new administration tools which allow administrators to easily control VMs running on their cloud. The administrators can also choose to give more information to the user, e.g., allow them to inspect on what physical machines a their virtual machines are running.

In addition, the release also includes bugfixes and additions to documentation. Check out the changelog for full details.

As always, we want to express our gratitude to our open source community for their contributions to this release. We would like to particularly acknowledge the work of Rob Rusnak who contributed the administrative tools as part of the Google Summer of Code project and Shao, Hsin (Jeff) who helped with LANTorrent testing. The features in this release were supported by the GSoC, OOI, and FutureGrid projects.
