OpenNebula 4.14 ‘Great A’Tuin’ Beta 1 released!

The OpenNebula project is proud to announce the availability of OpenNebula 4.14 ‘Great A’Tuin’ Beta1. This release ships with several improvements in different subsystems and components. The Sunstone interface has been completely refactored, for maintenance and performance reasons. Expect major improvements in Sunstone from now on. Also, we are sure you will like the subtle changes in the look and feel.

Several major features have been introduced in Great A’Tuin. One of the most interesting for cloud users and administrators is the ability to create and maintain a tree of VM disks snapshots. Now VM disks can be reverted to a previous state at any given time, and they are preserved in the image if it is persistent in the image datastore. For instance, you can attach a disk to a VM, create a snapshot, detach it and attach it to a new VM, and revert to a previous state. Very handy, for instance, to keep a working history of datablocks that can contain dockerized applications.

Also, in 4.14 snapshots are taken into account for quotas, accounting and showback, so cloud admins can keep track of disk usage in their infrastructure.

The ability to save VMs into VM Templates for later use is another feature that must be highlighted in this release. This new operation is accessible both from the cloud view and the admin Sunstone view. Of course, also from the command line interface.

One great improvement for cloud admins is a much better state management of VMs. It is now possible to recover VMs from failed state instructing OpenNebula to take the last action as success, to retry it or to make it fail gracefully, to recover for instance from failed migrations.

There are many other improvements in 4.14 (check the full list of changes in the development portal):

  • flexible context definition of network attributes
  • ability to import running VMs not launched by OpenNebula from all the supported hypervisors (including the hybrid ones, for instance now it is possible to manage through OpenNebula Azure, SoftLayer and EC2 VMs launched through their respective management portals)
  • the possibility to cold attach disks and network interfaces to powered off machines (which complement the hot attach functionality)
  • improvements in accounting to keep track of disk usage
  • better logging in several areas
  • the ability to pass scripts to VMs for guest OS customization

Overall, a great effort was put in this release to help build and maintain robust private, hybrid and public clouds with OpenNebula.

This OpenNebula release is named after Great A’Tuin,  the Giant Star Turtle (of the fictional species Chelys galactica) who travels through the Discworld universe’s space, carrying four giant elephants who in turn carry the Discworld. Allegedly, it is “the only turtle ever to feature on the Hertzsprung–Russell diagram.”

The OpenNebula team is now set to bug-fixing mode. Note that this is a beta release aimed at testers and developers to try these new features (not production environments) and send a more than welcomed feedback for the final release. There are a number of very interesting features that will make their appearance in the final release but not present in the Beta1, like for instance better support for Qcow2 for live snapshotting and GPU support for VMs.

Disk snapshots with Ceph backend was funded by Unity in the context of the Fund a Feature Program. Qcow2 snapshots implementation was funded by BIT.nl in the context of the Fund a Feature Program. GPU devices support was funded by SURFsara in the context of the Fund a Feature Program. Flexible network attributes definition in contextualization was funded by Université Catholique de Louvain in the context of the Fund a Feature Program.

Why Did We Choose OpenNebula for Runtastic?

Link to the original article at TheStack.com

runtastic-opennebula

Armin Deliomini is a Linux, virtualisation and database engineer at Austrian-based mobile fitness company Runtastic, and has made a rewarding journey from commercial cloud solutions – such as VMware and Oracle – in favour of completely open-source alternatives. Over the last two years Armin has implemented a private ecostructure for the Runtastic ecosystem and its 50 million users. Armin will be speaking today at Cloud Expo Europe taking place alongside Data Centre World, this week on the 11th and 12th March.

Since 2009 Runtastic has created apps, products and services for health and fitness tracking and management – a powerful infrastructure including around 300 virtual machines on thirty OpenNebula nodes, ensuring that 100 million downloaded apps and around 50 million registered users can access our services at any time.

We didn’t have a lot of time to decide on a technology to run our virtual environment. We had the classic vSphere environment in mind, but building an environment completely around opensource software spoke against a commercial virtual solution. We tested Ovirt, Proxmox and Openstack, the latter of which was very close, since we use Ubuntu in our overall infrastructure, and it was the most-hyped Opensource cloud solution at that time. A meeting with Tino Vasquez at the Netways booth at Cebit 2013 convinced us that OpenNebula was at least worth a thought.We set up a test installation; four months later our first production-grade OpenNebula cluster was fired up.

So why did we choose OpenNebula? Firstly, we liked the flexibility; in our business we don’t know exactly where the road ahead is leading. We had to find a technology that would grow with our needs and that we could adapt easily. We came at that time from a classic Virtualization background, with Vmware vSphere, and that was how we started with OpenNebula – classic virtual machines running on a hypervisor cluster that was managed by a central piece of software. But we also knew that this was not the future. OpenNebula gave us the comfort to start in a well known way, but at the same time gave us room to evolve.Our first set-up consisted of 16 KVM hosts and a Netapp storage serving NFS. In the beginning OpenNebula didn’t do more than give us an interface to start and stop machines, and to change their resource settings; but over time the situation developed very favourably. Our newly-launched machines are automatically included into Chef, and start doing their work within a minute. We also have the possibilty to start machines in external clouds in the event of resource shortages.

Our current projects are a new Cisco UCS Blade infrastructure operating as OpenNebula nodes, to lift our compute power to ~ 1000 cores, and Ceph as a future storage backend – a successor to our two NFS storages. We set up our first Ceph cluster in our preproduction environment recently.

We are no experts on OpenNebula, but then, we don’t have to be. It simply works…

Programme Open Cloud & Developer Park – Cloud Expo Europe 2015

We want to remind our community that OpenNebula will have strong presence in the upcoming Cloud Expo Europe 2015, which is only two weeks away on the 11th and 12th of March 2015 in ExCeL London. This is the biggest and best attended cloud event in the world , with over 300 top experts – including number 1 rated CIOs, Acclaimed Global Cloud Leaders, Cloud Gurus with HUGE twitter followings – all speaking in a compelling conference and seminar programme, which covers all the major technology and business issues.

The online programme for the Open Cloud & Developer Park, sponsored by the two leading open source Cloud Management Platforms, OpenNebula and OpenStack, is now available. The Park covers key open source cloud platforms, aiming to transmit technical knowledge and hands-on tutorials on today’s main open source IaaS platforms.

Moreover, the project will introduce a success story with Armin Deliomini, from Runtastic, at the CMSA theatre on Thursday 12th March at 12.15 – 12.40, to explain how OpenNebula saved them endless hours of tinkering!
