Technology

The first stable release of OpenNebula 5.0 Wizard has been published. The OpenNebula project is proud to announce the availability of the first stable release of OpenNebula 5.0 ‘Wizard’. This major update comes with several improvements in different subsystems and components, with minimal changes in the API and the VM life-cycle states, which embodies long overdue changes but implemented to minimize the impact and ensure backwards compatibility as far as possible.

Also, a new maintenance release 5.0.1 fixing bugs reported by the community has also been published this month, fixing fix Ceph pool names, VM Template update wizard, oned crashes when a context variable contains a filter, PCI element in KVM deployment file, better checks for IPv4 strings, wrong attach disk in vCenter, VM instantiate when NIC contains a fixed IP, migration for STOPPED and UNDEPLOYED states and the apptemplate generation. We would like to thanks all members of the community that contributed hugely with their evaluation of the beta, RC and final stable version and provided feedback on it.
Based on 5.0 Wizard, also a new release of vOneCloud, 2.0, is available for download. vOneCloud is an OpenNebula distribution optimized to work on small VMware vCenter deployments. This new release of the appliance, based on a tailored version of OpenNebula 5.0 Wizard to ease the provisioning of resources from vSphere based infrastructures, comes packed with exciting new features:

  • Datastore and VMDK image management, as well as import.
  • New Virtual Router Resource, to allow routing between isolated virtual networks.
  • More flexible vCenter VM naming, with a configurable prefix.
  • New resource pool mode, with the ability to select in which resource pool a particular VM is confined.
  • New OneFlow templates operations, like the ability to clone existing service templates.
  • Keep disks on done, to avoid deleting disks when the VM is terminated.
  • Instantiate to persistent, to easily create a rich VM Template catalog.
  • Dynamic VM reconfiguration, that can be performed while the VM is running or powered off.

Community

We cannot emphasise this enough. The OpenNebula community is continuously contributing to the OpenNebula maturity and success, and we would like to thank you all for your excellent feedback on the several betas and RC of 5.0 Wizard.
Also, the amazing job of the different translators has enabled the availability of the Sunstone web interface to 20 different languages. Kudos to you!
The community shows its engagement in integrations like this one between OpenNebula and the Happy module by EOLE team, GO bindings for the OpenNebula Cloud API (OCA) by Megam and OpenNebula and Foreman by Netways. This enriches the OpenNebula ecosystem and shows its health, thanks!
Also important is to spread the word, with initiatives like users groups and local meetups and workshops. Also welcome are reviews in blogs, like this one about vOneCloud 2.0 (In French), or this excellently crafted post on OpenNebula and Docker Swarm with consul.
And, as usual, is very good to be reminded about nice things, like for instance the amount of years we’ve been working to make OpenNebula a mature product that you can find today.

Outreach

The next OpenNebula Conference in Barcelona in October 2016 will take place 24 to 26 of October. The preliminary agenda has already been published, the final version will soon be available. If you are willing to attend, the early bird will be available until 15th of July.

OpenNebula 5.0 Wizard is around the corner! With the Beta version released recently, the team is baking a release candidate, and is planning a final stable Wizard release for mid June. Wizard is in feature freeze, and the effort is focused on solving bugs. We appreciate your feedback if you have the time to try out the Beta version!
This are the highlighted gems that you can find in Wizard:

  • revamped Marketplace, now a first class citizen in OpenNebula, to import/export images to and from any datastore (including the new vCenter datastores)
  •  vCenter storage management, including datastore selection, disk hotplug, vmdk creation, cloning and deletion; and full integration with the new Marketplace functionality. Also, vCenter resource pool selection for deployed VMs will be possible.
  •  fully integrated virtual router management (including default and transparent HA for routers). Link virtual networks together using a robust HA router, that will come out of the box in OpenNebula
  •  revisited Sunstone style and interface changes (sneak peek), including an extension of the Cloud View available operations, to iron out the wrinkles in the user experience
  •  instantiate to persistent! Do not lose your VM changes, OpenNebula will create a new VM Template and preserver the disks of a VM, even if they are non-persistent.

Check the full list of feature in the development portal.

A great effort has been put in the new documentation. The new documentation focus on the cloud architects, admins and end users, and extra care has been taken in separating the different technologies supported by OpenNebula.
OpenNebula needs you! We are looking for translators for Sunstone. If you are a native speaker of any language other than english, we would appreciate your effort in making OpenNebula more widely adopted. It is very easy: the existing translations can be updated and new translations submitted through our project site at Transifex

Community

Members of the community has been as helpful as always. Contributing in different ways, you are the reason why OpenNebula is such a useful project.
Devuan folks have contributed a 1.0 Devuan image to the OpenNebula marketplace. Now you can try Devuan in your OpenNebula cloud, it is just a few clicks away!.
Keeping the morale high is really important, especially in hard development times such as this one (5.0 is getting this much love!). That is why getting this kind of feedback is so important, it is the fuel that keeps us going.

New Sunstone layout in @opennebula look awesome

And it is good to know that Wizard is appealing not only visually, but also feature-wise.

@opennebula beta One 4.9 replace HW router #VyOS & #OpenvSwitch, truly awesome stuff

As with translation, having material in your own language about a technology is very important to reach everyone that may be interested in it. That is why efforts like this one (in Spanish) are very, very welcome.
As usual, we want to give the thumbs up to the community for their active involvement in the OpenNebula forum, specially helping newcomers. This is very important for the adoption of the project.

Let’s see what’ve been brewing in our amazing community this past month.

Our friends at LINBIT have published an excellent blog post describing the new DRBD manage add-on for OpenNebula to achieve High Availability in the storage backend. Very interesting, keep up the good work!

opennebula-diskless
CipherSpace have contributed an awesome blog post describing their experiences adapting OpenNebula to their needs to serve their customers. In particular, it is very interesting the extensions to build Private Virtual Datacenters. A must read!

With the flexibility provided by the OpenNebula platform, we were able to create a valuably different solution in the PvDC model with nearly all our effort in the conceptual development of what we wanted to offer and the testing of small adaptations of OpenNebula

Other contributions are also welcome! For instance this extension to the EC2 server authorization, a Devuan (for those init lovers!) OpenNebula ready image in the marketplace and also a new CoreOS image also in the marketplace. Also interesting this automated way of deploying OpenNebula in HA.
We want to thank the community for their active involvement in the OpenNebula forum. Helps for helping the newcomers and having such a good vibe!

OpenNebula 5.0 is brewing and the team is closing new features and liking the overall feeling of the next major upgrade. We are set for a beta release of 5.0 this very same upcoming month of April, so stay tuned for the following:

  • revamped Marketplace, now a first class citizen in OpenNebula, to import/export images to and from any datastore (including the new vCenter datastores)
  • vCenter storage management, including datastore selection and disk hotplug, a full integration with the new Marketplace functionality. Share VMDKs among OpenNebula instances! Also, vCenter resource pool selection for deployed VMs will be possible.
  • fully integrated virtual router management (including default and transparent HA for routers). Link virtual networks together using a robust HA router, that will come out of the box in OpenNebula
  • revisited Sunstone style and interface changes (sneak peek), including an extension of the Cloud View available operations, to iron out the wrinkles in the user experience

Continuing with the series of Docker integration posts, this past month this entry explained how to get Docker Swarms deployed with OpenNebula. The idea is to get Docker Swarm to build a cluster out of a collection of Docker Engine VMs deployed in OpenNebula with Docker Machine. Docker Swarm is native clustering for Docker, delivering many advantages, like scheduling, high availability, etc.

docker-swarm-opennebula
If you need professional support for your OpenNebula cloud, remember that OpenNebula Systems has extended the support services portfolio to include the Operating System of the virtualization nodes and the controller (which can be CentOS and/or Ubuntu), the hypervisor (libvirt and KVM), networking technologies as VXLAN/VLAN 802.1Q and Ceph as storage backend.

Community

The OpenNebula community never ceases to amaze us. Contributions to the common knowledge pool around OpenNebula deployments add huge value to the open source project. Several contributions were made this past month in this regard, let’s see the highlights.
A great addition is related to the LXCoNe addon with a very detailed and complete post. LXCoNE, a virtualization and monitoring driver for OpenNebula that comes as an add-on to provide OpenNebula with the ability to deploy LXC containers. It contributes to achieve better interoperability, performance and scalability in OpenNebula clouds. Right now, the driver is stable and ready for its release.
Also do not miss this post and contribution by TeleData, enabling the feed of monitoring data in the form of graphite metrics. Great work! And we blush with your words too!

In our opinion OpenNebula works like a charm. It is open and flexible. OpenNebula is one of the most mature, comprehensive and valuable Cloud-Stack available in the market

Overview (Zones + Clusters + Ressources)

And last but not least, our friends at LINBIT have contributed their OpenNebula driver for DRDB integration as an addon! This driver allows for highly available storage using DRBD9 + DRBD Manage in OpenNebula.

We are, as usual, thankful to have this wonderful community. Two thumbs up!

The OpenNebula team keeps working in OpenNebula 5.0, the next major upgrade that will incorporate a wealth of new features, keeping a smooth upgrade path. And no, this is no easy task folks. But we will make it happen.

OpenNebula 5.0 is a revolution around the corner. In a few weeks, a beta version will come out featuring the following highlights:

  • revamped Marketplace, now a first class citizen in OpenNebula, to import/export images to and from any datastore (including the new vCenter datastores)
  • vCenter storage management, including datastore selection and disk hotplug, a full integration with the new Marketplace functionality. Share VMDKs among OpenNebula instances!
  • fully integrated virtual router management (including default and transparent HA for routers). Link virtual networks together using a robust HA router, that will come out of the box in OpenNebula

5.0 will also feature a myriad of interface changes, including an extension of the Cloud View available operations, to iron out the wrinkles in the user experience and a long list of other features.

As you may have noticed, interest in Docker is surging. We see OpenNebula as the perfect IaaS support for Docker, and as such our strategy regarding integration of Docker ecosystem within OpenNebula is to follow a “container as a service” approach. This is containers within VMs, not replace KVM/ESX with containers to ensure we maintain strong multi-tenancy. First we want to integrate OpenNebula with Docker-Machine to be able to build a container environment within your cloud. This feature is very advanced, as you can see in blog post. The second step would be to integrate tightly with Docker Swarm to be able to create Swarms using the OneFlow component.

Community

Lots of exciting things are happening in the OpenNebula community. Collaborations, contributions, and yes! even praise. Let’s review the highlights.

LINBIT has developed a new set of drivers to give OpenNebula support for the excellent DRBD functionality. Check an informative demo in this video.

A new release of the Perl binding for the OpenNebula Cloud API (OCA) is also worth noting if Perl is your sysadmin scripting language of choice. No excuse to make all the chores automatically in your cloud infrastructure now!

A freshly brewed integration of OpenNebula with professional VDI platform has been announced by UDS Enterprise, to be available in the upcoming 2.0 release of their software.

Our friends at NodeWeavers never stop. Take a look at their new family addition. Cute is an understatement, and since it is based on OpenNebula, powerful another one.

World wide adoption of OpenNebula is a fact. If more proof is needed, this is an excellent one. OpenNebula has been translated to the Persian language! Check this out.

Overall, we are very proud of the OpenNebula community. OpenNebula won’t be half as good without you guys, keep it up!

The OpenNebula team, after the release of a new maintenance release for Great A’Tuin, the 4.14.2, is working around the clock on the next upgrade of OpenNebula, v5.0.
This new version will come packed with features and interface changes to iron out the wrinkles in the user experience, to make the experience managing and using an OpenNebula cloud even smoother. vCenter storage management (you are right, including datastore selection and disk hotplug), fully integrated virtual router management (including default and transparent HA for routers), marketplace datastore to easily import/export images to other OpenNebula clouds (we think this is a badass feature), Cloud View improvements, and a long list of other features. As a teaser see this blog entry about resource tagging in Sunstone to keep VMs, networks, images and templates perfectly organized.

Results from the last survey, aimed to understand the use of OpenNebula by the community, has been analyzed and published in the blog. After a careful filter, 190 organizations were chosen as a representative sample of the community. The main changes with respect to the last, 2014 survey are (read a more extensive report here):

  • OpenNebula shows its increasing maturity, with 73% of deployments in production compared to 62% reported in our previous survey.
  • Growth in North America has accelerated, now representing 30% of responses, up from 20%.
  • KVM provides the majority of OpenNebula support, growing from 48% to 79%.
  • There is a high rate of adoption in VMware environments from 28% to 37%.
  • Ubuntu grows from 36% to 40% and Debian falls from 33% to 22% as OS to build the cloud.
  • The use of the EC2 cloud API decreases from 25% to 10%.
  • The use of Ceph has grown considerably from 17% to 40%

Community

The OpenNebula community never sleeps! Well, that may be an overstatement, but certainly when they don’t they contribute to the common knowledge as well as come up with cool integrations to enhance the already mighty power of OpenNebula clouds. Floating IPs for OpenNebula can be easily achieved now thanks to this nifty tool developed OpenNebula clouds, developed by the same authors as CloudVAMP and Docker drivers.

Billing is crucial for VPS providers, which will greatly benefit from this provisioning module for Blesta which can be plugged into OpenNebula infrastructures.
It is crucial for an open source project such as your favourite cloud management platform to receive its users feedback. As you may heard from us before (once or twice), our roadmap is defined using our knowledge of our user and community developer needs. This is why it is so important messages like this one, with very useful feedback to be taken into account in future OpenNebula releases. Thanks, keep up the good work!

Remember our December newsletter? We said you should stay tuned for the OpenNebula TechDay schedule in 2016. If you did then you already know about the quite a few already scheduled TechDays around the world for this year, to which we promptly added others in US. The OpenNebula Cloud TechDays are full day events to learn about OpenNebula with a hands-on cloud installation and operation workshop, and presentations from community members and users. TechDays hosts have an important role, and that is the local promotion of the event to gather OpenNebula enthusiasts in this technical event. If you are interested in participating in (or hosting) any of these TechDays agenda let us know.

TechDays

OpenNebula was spoken of in the Journée interministérielle du libre 2016 in France, country which recommends OpenNebula in their open source software reference list. Rubén S. Montero, our chief architect, gave an interesting interview to DatacenterDynamics magazine, check it out.
OpenNebula Systems also announced this month its training plans for 2016 for Europe and US. These courses are designed to train cloud administrators to properly operate an OpenNebula infrastructure. Please contact us if your would like to request training near you.

OpenNebula 2015: Year in Review

This has been a very interesting year in the Cloud Computing field in general, and in OpenNebula in particular. It looks like the field is consolidating, and we are past the Peak of Inflated Expectations slowly moving into the Plateau of Productivity. This can be inferred from the increasing number of enterprises that are implementing their in-house private clouds and offloading their computing needs to public cloud providers, showing that the paradigm did take off and it’s soaring towards computing efficiency.

In this regard, we are proud that OpenNebula celebrated this year its 8th anniversary, showing a degree of maturity fit for the most demanding production environments. The OpenNebula project is proud to deliver a truly open, vendor-free, user-driven software to build private and hybrid clouds, with design principles that focus on simplicity and flexibility. Our philosophy is not to break with the previous outstanding work in datacenters, but rather extending its functionality to take advantage of the cloud computing benefits. We think this is a unique vision in the field, and OpenNebula is the product of this believe.

With 2015 coming quickly to a close, we’d like to review what this year has meant for the OpenNebula project. You have all the details about the great progress that we have seen for the OpenNebula project in our monthly newsletters.

Two major releases were published this year: 4.12 Cotton Candy and 4.14 Great A’Tuin. Moreover, three maintenance versions were released to fix bugs and polish features. Several maintenance versions of AppMarket were also released.

4.12 Cotton Candy shipped with several improvements in different subsystems and components. For the first time, OpenNebula introduced the ability to generate cost reports that can be integrated with chargeback and billing platforms, and also presented to both the administrators and the end users. Each VM Template defined by the Cloud administrator can define a cost per cpu and per memory per hour. Extensively used features like SPICE, Security Groups and VXLAN were firstly seen in Cotton Candy

One of the main focus of 4.14 Great A’Tuin has been the Sunstone interface, which has been completely refactored for maintenance and performance reasons. However Great A’Tuin is probably the release of OpenNebula to date that features more new functionality. GPU support is a great addition to support HPC oriented infrastructures, importing existing running VMs into OpenNebula for all supported hypervisors (including the public ones), fully supported disk snapshots for Ceph and qcow2, image resizing, ability to ability to save VMs into VM Templates for later use, flexible context definition of network attributes, the list goes on and on. We feel this is the most mature and rich OpenNebula version, but we are not stopping here since work towards 5.0 has already started.

Moreover, four major releases of vOneCloud were released this year. Thanks to the amazing user feedback, the a virtual appliance for vSphere that transforms an existing vCenter deployment into an automated, self-service private cloud in a few minutes, is quickly growing its feature set to deliver a reliable, robust and mature product. vOneCloud exposes a multi-tenant, cloud-like provisioning layer, including features like virtual data centers, self-service portal, or hybrid cloud computing to connect in-house vCenter infrastructures with public clouds. vOneCloud seamlessly integrates with running vCenter virtualized infrastructures, and can be set up if a few minutes and import the existing infrastructure resources, including running VMs.

We would like to thank the community members that have contributed with patches, documentation and feedback to the matureness of OpenNebula. Also, to the various organizations that have contributed to enhance OpenNebula through the Fund a Feature program: Blackberry, Echelon, Unity, BIT.nl, SURFsara and the Université Catholique de Louvain. We look forward to your contributions to code development!.

An Engaged Community of Users

The OpenNebula community is as healthy as ever, and fastly growing. The contributions to the software and its roadmap are vast, and cannot be briefly mentioned. We wanted to highlight a few integrations and feature extensions though, like one onesnooper, StorPool, Vagrant, LXC, nodejs binding, Saturnring, Kerberos, Chef, CloudVAMP, Docker, ZFS, and many many more. We are proud of our very much alive, proactive and engage community!

There are tens of thousands of deployments around the globe and OpenNebula is parked in some of the biggest organizations out there including Industry and Research leaders. OpenNebula roadmap is defined by its users needs. We just performed a survey to require input for the list of features that will be tackled for the next major update, OpenNebula 5.0.

2015 also marked the end of the distribution mailing list as the main mechanism of communication with our community, in favour of the new online forum, to keep this communication agile and fruitful.

We would like to thank all our users! It is out of scope to name all new users, but we want to give a wholeheartedly warm welcome to those new users that shared their experiences through our blog: Unity, Universidad Politécnica de Valencia, PTisp, Avalon, China Mobile, Rentalia and BIT.nl. If you are using OpenNebula, you are very welcome to contribute your integrations and experiences by writing a post in our blog or submitting your integration to the OpenNebula Add-on Catalog.

Spreading the Word

Spreading the OpenNebula word is of the uttermost importance for the project. The brightest highlight is, as usual, the OpenNebulaConf 2015. This year it was held in slick hotel Barcelo Sants in Barcelona and featured very interesting talks by relevant users: Runtastic, Unity, Citrix, RedHat, Fermilab, … Check out the videos, slides and pictures to get a glimpse of what you missed. A lot of new ideas for features and collaborations were fostered in this event, so expect a great and fruitful 2016.

In 2015 members of the OpenNebula team participated in several around the world. We want to highlight the VMworld Europe 2015 in Barcelona, Cloud Expo Europe in London and the Open Cloud Day in Bern. These events are great opportunities to evangelize people into what we think is the greatest Cloud Management Platform.

A number of high quality OpenNebula TechDays, full day events to learn about OpenNebula with a hands-on cloud installation and operation workshop and presentations from community, were held this year. Check out the agendas of the Prague, Boston, Paris and Ontario TechDays.

We want to thank all organizations that hosted a TechDay in 2015 for their hospitality. We are organizing the schedule of TechDays for future months, send us an email or send it to the community discuss mailing list if you are interested in hosting a TechDay event. We also look forward to proposals to create a user group in your area. In a few days we will announce OpenNebulaConf 2016.

***

We are thrilled to have a community as vibrant and engaged as the OpenNebula one. Two thumbs up to you all for helping us building a great cloud management platform that solves real world problems.

We’d also like to take this opportunity to wish you happiness and prosperity in 2016 to you and your loved ones!

OpenNebula Newsletter – November 2015

Check this Newsletter to find out the what kept us busy this month: latest developments, events and future plans for the upcoming months.

We are very proud to celebrate the 8th birthday of the OpenNebula Project. Eight years developing OpenNebula has been a great adventure and experience for the OpenNebula project, and we are sure that it has been also a great ride for you. Thanks for being such an excellent open source community!

Technology

The team has released this past month a new maintenance release for Great A’Tuin, the 4.14.2. This release comes with several bug fixes found after the 4.14 release. These bug fixes cover different OpenNebula components like the Cloud View self service portal, Sunstone web interface, OpenNebula Core and several drivers (VM, IM, Network, Auth), as well as with the OneGate component. Check the full list of bug fixes in the development portal.

This maintenance release also includes several improvements in several OpenNebula components. Cloud View and Sunstone have very interesting new features that boost usability and productivity, whereas other areas have been improved for security and reliability. vCenter integration has also received its share of love, with interesting new features like VMware Customization spec support. Check out the full list of improvements introduced in this release in the documentation.

A new version of the AppMarket, 2.1.0, has also been released. This new version solves issues reported by the community and has been verified to work with OpenNebula 4.14.2 and the new Sunstone design.

And last, but not least, new version of the context packages has been also released. This new version of the packages come with new features like support for contextualization in EC2 VMs (yay!), OneGate token for vCenter and EC2 VMs, and better SSH configuration support. From now on the context packages are splitted in two, the version for KVM, XEN and vCEnter and other for EC2 instances.

The project is also committed to produce needed documentation to aid users designing and building their clouds. In this regard, it may be of your interest the new VMware Cloud Reference Architecture, to define our recommendations to build private and hybrid clouds on top of vCenter infrastructures.

Community

There are amazing projects featured by the OpenNebula community. We want to let you know about these quality projects in this section, as we are sure they might be of your interest.

Our friends at Universidad Politécnica de Valencia are producing great tools for OpenNebula. For instance, CloudVAMP, a vertical elasticity oversubscription manager for OpenNebula. Check it out if you want your VMs to adjust their capacity automagically!. Another great contribution from them is ONEdock, a set of drivers for OpenNebula to enable the use dockers as if they were virtual machines.

Support for new storage backends is a much welcome addition to OpenNebula, like this new ZFS driver for OpenNebula, enabling the the possibility of using ZVOL volumes instead of plain files to hold the Virtual Images.
Documentation is a great asset, often underestimated. We want to a big thanks to Adrian for their OpenNebula tutorial in spanish, very useful to foster OpenNebula adoption. Also important for adoption is the ability to roll out OpenNebula easily. That’s why we also want to endorse initiatives like this new Chef cookbook for OpenNebula. Thanks!

It is very important to maintain the OpenNebula ecosystem up to date!! That is why we love the work by our community, like for instance the StorPool driver which is now up to date for OpenNebula 4.14.2. Good work!

Outreach

Technology

Autumn is here! Leafs are falling, rains from time to time and it’s getting cold. So the OpenNebula team has decided to lock themselves up and prepare a worthy maintenance release for Great A’Tuin, the 4.14.2. It will come with a lot of bugfixes and several features. But don’t worry, we will be extra careful to ensure compatibility, specially taking into account that it is a maintenance release after all.

For instance, 4.14.2 will bring improvements in the hybrid connectors the ability to substitute PUBLIC_CLOUD attributes á la context, extract monitoring information (CPU and Networking) from EC2 Virtual Machines through the use of CloudWatch and User Data for EC2 will be available as a Sunstone user input (that is requested from the end user at the time on instantiating a Virtual Machine).

4.14.2 will also bring important improvements to vCenter integration. Large scale deployments will benefit from the pagination of vCenter import dialog, as well as multi-cluster VM templates. An important addition is also the integration with VMware guest customization, which leverages the guest OS support for customization that traditionally exists on VMware infrastructures.

Also, Sunstone will bring good news for developers, with accommodations to ease third party integrations, like the improvement of the mechanism to add external tabs. You can check the complete list of changes in the development portal.

We see the benefits in Docker, and want to help our admins to deploy their favorite Docker shipped appliances in their OpenNebula infrastructures. That’s why we have integrated OpenNebula within Docker Machine. This allows you to experience the best of both worlds: by using Docker with OpenNebula developers will use Docker transparently, but OpenNebula admins can control where these VMs are executed.

The AppMarket is getting its share of love, and a new version will be published in a few days with full compatibility with OpenNebula 4.14.2, as soon as the maintenance release is out.

The team has also released a new version (1.8) of vOneCloud. This new release of the appliance, based on a tailored version of OpenNebula 4.14 Great A’Tuin to ease the provisioning of resources from vSphere based infrastructures, comes packed with exciting new features, like the ability to configure the deletion of disks after finishing the VM lifecycle, friendly VM display name in vCenter, better naming on resource import and improvements in the Control Panel to further configure the vOneCloud appliance.

Community

The OpenNebula community was busy this month attending the OpenNebula Conference. But those that couldn’t make it, where also active in other ways.

Our friends at BlackBerry announced recently announced a new chef driver for OpenNebula. This driver comes with additional chef resources to manage OpenNebula: templates, images, vnets and leases!

Also worth noting that our friends and OpenNebula users at Harvard are hard at work designing their OpenNebula based infrastructure. It will definitely work!! People are also growing fond of vOneCloud, and lot of new users are coming due to our participation in the VMworld. More details in the next section.

One very important aspect of software development is maintenance. We understand this in the OpenNebula project, and do our best to keep a steady release cycle, provide a migration path and, specially, keep backwards compatibility. For this reason, we appreciate that our add-on ecosystem follows the same principles, like the lxcone set of drivers, that recently announced a new version.

Outreach

The third OpenNebula Conference was a great success! We love our community, seriously guys, you rock big time. Three days packed with interesting talks and great experiences exchange in the ‘hall track’. A great set of sponsors showed their integrations and use of OpenNebula, and their added value. We hope you liked the organization and the venue, and of course, the choice of food and places for the social events. We had a blast organizing it, and all the team feels it was a productive event for the attendees. Let’s hope we are right, we are willing to see you next year! We would like to take this opportunity to also thank our Platinum Sponsors PTisp and StorPool; Gold Sponsors ungleich (check out their summary of the conference), Xen Server and NodeWeaver; and Silver Sponsors Runtastic and No Limit Network.

Track

We uploaded the slides of the talks and you can find here the pictures of the conference. Check out the great keynotes of Unity and Runtastic, the to-the-point (as always) and hugely amusing talk by Carlo Daffara, the BlackBerry lightning talk … a wealth of information if you are running or planning to run an OpenNebula cloud. Videos will be available soon, stay tuned!

Hall TrackColocated with the OpenNebula Conf was a new edition of the CentOS Dojo. Check out the agenda, you can find the slides and videos of the talks in the CentOS wiki.

The team was also present in the VMworld Europe 2015 in Barcelona. A great event, where we introduced vOneCloud 1.8, the open replacement for vCloud director. It was awesomely well received, we hope it accommodates a wide range of use cases.

We would like to remind you that the third OpenNebulaConf is around the corner. If you haven’t already, register and meet us in Barcelona!

Technology

We have left summer behind, and are fastly approaching winter. The team has released the final stable version of OpenNebula 4.14 ‘Great A’Tuin’. Like leaves in fall, numerous features landed in this new release. You can check the exhaustive list of changes in the development portal.

The new ability to import VMs is worth highlighting from any supported hypervisors, including the hybrid ones. Have you got any Amazon VMs running and want to manage them through Sunstone? No problem! you can have OpenNebula aware of them in a breeze through the import dialog. We have prepared a screencast showing this feature, check it out, you won’t be disappointed!

4.14 includes the ability to manage disk snapshots. 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. This is useful to a variety of scenarios, for instance, before a system upgrade. If unsure how the management is offered through Sunstone, take a couple of minutes to check this video.

Snapshots

GPU support is now available to give raw access through PCI passthrough to specially calculation hungry VMs, like those found in HPC environments. There is no overcommitment possible nor sharing of GPU devices among different Virtual Machines, so a new type of consumable has been defined in OpenNebula and taken into account by the scheduler.

gpupcilist

Great A’Tuin comes packed with features. And when we say packed, we really mean it! image resizing on boot time, ability to save VMs into VM Templates for later use, better state management of VMs, flexible context definition of network attributes, 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,… and many more.

We want to thank our community for the excellent feedback on this important release, packed with features. It is of the utmost importance to fine tune OpenNebula, so thanks! now is time to upgrade your OpenNebula instance, and provide feedback in case you find any bug, to help us deliver a quality maintenance release, 4.14.1. Several organizations have sponsored the project through the Fund a Feature Program: disk snapshots with Ceph backend was funded by Unity, Qcow2 snapshots implementation was funded by BIT.nl, GPU devices support was funded by SURFsara and flexible network attributes definition in contextualization was funded by Université Catholique de Louvain.

The team is also working on a new version of vOneCloud, based on 4.14 and with extra features for vCenter management. It will bring significant advances in guest customization options. Stay tuned!

Community

September is a good month for our engaged community, with lots of different contributions that give value to the project.
Contributions that widens the OpenNebula ecosystem are always welcome, and show the good health of the OpenNebula open source project. For instance, the Saturn OpenNebula driver that enables OpenNebula to use Saturn -a scalable iSCSI block storage- as the storage backend for a persistent block device datastore.

Moreover, a project for integrating OpenNebula and Kerberos are also very good news. This will help securing OpenNebula deployments with the network authentication protocol, the team will evaluate this integration for its inclusion in future releases.
Besides technology contributions, it is also rad to see OpenNebula power users and their awesome deployments. Like this one we recently learned about: a new HPC cloud cluster, aimed at unravelling the mysteries of the Oort Cloud, powered by your favourite Cloud Management Platform. Cool, isn’t it?

The project also runs on messages like this one. Very happy to make possible important HPC infrastructures for our users. Keep it up! Little hacks on how to make OpenNebula resemble your ideal system are also very well received, like this mini howto on how to change the Sunstone login page background by CESGA. Way to go! We hope you are as comfortable using OpenNebula as we are developing it.

Our partners also make important contributions to the project, like this tweet by Microsoft Azure advertising the OpenNebula 4.12 Sandbox present in the Azure marketplace, lowering the barrier in case you want to try out OpenNebula features and also its powerful hybrid drivers.
