OpenNebula Newsletter – January 2016

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 starting this 2016 willing to share with the OpenNebula community another chapter of excellent cloud management. If you, as we do, like planning ahead check the sponsorship opportunities for the next OpenNebula Conf 2016, due in October in Barcelona. Take a look also to the projected OpenNebula TechDays for this year.

Technology

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!

Outreach

Recently after our last OpenNebula Conference (talks, slides,pictures), the next, 2016 edition have been announced!. We know it is hard to plan that much in advance, but if you are willing to attend and can save now the date you can take advantage of a huge 40% discount in your Conf tickets. More information is available from the event site.

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.
Members of the OpenNebula team will be present in the following events in upcoming months:

  • VMworld 2016 US, August 28 – September 1, Las Vegas (Mandalay Bay Hotel & Convention Center), Nevada, US.
  • VMworld 2016 Europe, October 17 – 20, Barcelona (Fira Barcelona Gran Via), Spain.

Remember that you can see slides and resources from past events in our Events page. We have also created a Slideshare account where you can see the slides from some of our recent presentations.

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.

Solving Real User Needs in Innovative Ways

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

The third edition of the third OpenNebula Conference was a great success! Three days packed with interesting talks and great experiences exchange. It was a great success thanks to the support and participation of all of our community members, speakers, sponsors and friends. If you missed the conference, now you have a chance to watch the talks in our YouTube channel, download the slides from the slideshare account or take a look to the pictures of the conference.

The third OpenNebulaConf was a great success. Great location, great people, great experiences exchange an great food! Check the Outreach section for the aftermath and stay tuned because in a few days we will publish the photos, slides and videos of the presentations.

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.

OpenNebula Newsletter – August 2015

Check this Newsletter to find out the what kept us busy this month, including the latest developments and events of the OpenNebula project and the community during this last month of August, and the plans for the upcoming months.

We would like to remind you that the third OpenNebulaConf, due in October in Barcelona, is around the corner! You are still in time until the 8th of September for the early bird discount.

Technology

August warm haven’t had an impact on the dev team! No slugginesh after the release of the first Beta of OpenNebula 4.14 ‘Great A’Tuin’. 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!

As mentioned, the team has not been drowsy at all. A few more features are currently being polished to make their debut in ‘Great A’Tuin’. For instance, the ability to resize an existing disk for all the supported OpenNebula backends. If your VM needs more disk space than the one provided by the images used for its disk, you can now set a new size prior to instantiate the VM, OpenNebula will grow the disk and the guest OS will adapt the filesystem to the now bigger disk at boot time. OpenNebula cloud admins can now maintain a VM Template catalog with different disk sizes without the need of cloning and storing the same disk with different sizes.

Another great addition for 4.14 is the support of GPU access from Virtual Machines. This is great news for HPC and science clouds, since virtualized applications can get now the performance boot of the direct access to a GPU card.

screenshot_from_2015-08-27_19-28-12

Also, the team has worked in stabilizing the previous and exciting new features: qcow2 and Ceph snapshots (live in the case of qcow2), Sunstone refactoring, importing running VMs, the possibility to cold attach disks and network interfaces to powered off machines; improvements in accounting to keep track of disk usage (with the ability to control disk consumption through quotas); better logging in several areas; the ability to pass scripts to VMs for guest OS customization; and many others.

Community

OpenNebula community keeps at it even during the estival season. For instance, working on supporting the latest versions of OpenNebula stable in your favorite linux platforms, directly from their repositories. A good example of this is the new packages for Debian unstable.

It is always nice to see OpenNebula being adopted, but if the deployment is within an institution as prestigious as Harvard University, the is double the fun! We are sure OpenNebula will meet their expectations and we are thrilled about the feedback they will surely provide.

A good example of how vibrant the OpenNebula community is can be seen in the fact that its ecosystem doesn’t stop to grow! A new OpenNebula storage driver for Saturnring open-source scale-out iSCSI-based block storage is most welcome and very useful addition. Thanks!

We want to remind our users that OpenNebula Systems, the company behind the OpenNebula Project and vOneCloud, has established a new subsidiary to oversee all business operations and to support the OpenNebula community in the U.S. If you are interested in supporting the OpenNebula community in the US, let us know.

Technology

The team has released the first Beta of OpenNebula 4.14 ‘Great A’Tuin’. We hope you enjoy using it as much as we did developing it. The new features and usability improvements present in this new release couldn’t have been without our community support and feedback. We want to thank you all for your contributions to make OpenNebula as mature and reliable as it is today. Every little helps!

One of the most interesting new features for cloud users and administrators is the ability to create and maintain a tree of VM disks snapshots, for Ceph an Qcow2 backends. Also important, the ability to save VMs into VM Templates for later use greatly improves the usability of OpenNebula based clouds, to which also adds the much better state management of VMs for recovery from failures.

snapbeta

There are many other improvements in 4.14, like a more flexible context definition of network attributes; the 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 complements 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; and many others. A great effort was put in this release to help build and maintain robust private, hybrid and public clouds with OpenNebula.

There are some features the team is still polishing and decided not to include in the Beta1- For instance another major feature is the ability to resize an existing disk for all the supported OpenNebula backends. If your VM needs more disk space than the one provided by the images used for its disk, you can now set a new size prior to instantiate the VM, OpenNebula will grow the disk and the guest OS will adapt the filesystem to the now bigger disk at boot time. The disk space won’t be an issue anymore. To support this feature, a new set of context packages has already been released so you can start preparing your images for disk resizing.

Another huge feature to support HPC oriented infrastructures is the consumption of raw GPU devices existing on a physical host from a Virtual Machine. A new type of consumable has been defined in OpenNebula and taken into account by the scheduler. VMs can now request a GPU, and if OpenNebula finds one free resource of type GPU available, it will set up the VM with PCI passthrough access to the GPU resource.

Channels to help people try out OpenNebula is a hassle-free way are key to foster adoption of OpenNebula. The OpenNebula project is well aware of this, so it has teamed up with Microsoft to offer a new OpenNebula Sandbox in the Azure Marketplace. Currently you can try out 4.12.1, but we will update as usual all the SandBoxes to Great A’Tuin as soon as the stable version is out.

Community

Summer is upon us, and this does not prevent the OpenNebula community to keep contributing to the rich ecosystem. Since the Beta1 is out, we want to make a call for feedback. Please install in a test environment Great A’Tuin, and let us know through the community forum. It is your feedback what makes OpenNebula user friendly, so thanks in advance!.

For the team working in the cloud trenches, comments like this one are like a blow of fresh air that keep us going, stronger, towards cloud excellence. Thanks!
Contributions to the OpenNebula ecosystem are always great news, to enable integrations with new components, develop new functionality and ease the day to day cloud operation. But if they are maintained such as this nodejs binding for the OpenNebula API, then we are talking about quality ecosystem. Excellent contribution.
Extensions to the OpenNebula contextualization system are also always good news, like this new contextualization package for Gentoo written as an Ansible playbook.

Another great contribution enables OpenNebula to manage LXC containers. LXC is a userspace interface for the Linux kernel containment features. It lets Linux users easily create and manage system or application containers. With this amazing contribution OpenNebula can deploy LXCs with the intrinsic improvements in performance. The new addon includes motorization and virtualization drivers, kudos to Sergio Vega and José Manuel de la Fé for their contribution.

Outreach

The upcoming third edition of the OpenNebulaConf will be held in Barcelona this October 2015. The Conference is a great opportunity to meetup and share your OpenNebula experiences with the community.

OpenNebula Newsletter – June 2015

Check out what kept us busy this June. This Newsletter contains the most worthy developments and events of the OpenNebula project and the community during this last month, and the plans for the upcoming months.

We want to remind our users that OpenNebula Systems, the company behind the OpenNebula Project and vOneCloud, has established a new subsidiary to oversee all business operations and to support the OpenNebula community in the U.S. If you are interested in supporting the US OpenNebula community or contact us, let us know.

Technology

The OpenNebula team is not fooling around with the 4.14 release. We are settling on a code name for the release (do you like ‘Dark Horse’?), and meanwhile adding an impressive array of features. Probably the main highlight is the new snapshot management feature, that will let perform disk snapshots and maintain a history of them. The initial support would be only for Ceph (it is our storage backend of choice for medium to large deployments after all, read our reference architecture), and qcow2. OpenNebula will be aware of snapshot sizes, and allow to enforce quotas and also to report consumption via the accounting mechanisms. Pretty neat, is it not, hosting providers?

Another big highlight would be the inclusion of a new type of consumable, GPU. A VM would be able to consume GPUs, using PCI passthrough, to gain exclusive access to GPU PCI cards. Pretty neat, is it not, research institutions and supercomputing centers?

Sunstone is being reworking behind the scenes, and although final users will only notice minor changes in the GUI, rest assure that this is a very important feature for the future of Sunstone. Keep an eye on it!

Other features we are working on is image resizing (finally), system datastore flush for maintenance, import VMs capabilities for hybrid hosts, improved fault management with the inclusion of new VM state transitions (no VM left behind), improvements in the network context management, and many more. As mentioned before, we are not fooling around with Dark Horse, be sure to be ready for the beta version due at the end of July.

This month, a new set of contextualization packages was also released, with several nifty additionals like the ability to pass scripts directly to be executed at boot time, without having to create them first in the files datastore.

A new version of the drop in replacement for vCloud, vOneCloud, was also released. vOneCloud 1.6 comes with several improvements, like capacity resizing, resource pool confinement, improvements in VNC, and more. Make sure you update using the awesome one click updated.

Community

Keeping a healthy community is key for an open source project. The OpenNebula community is growing every day, contributing new pieces to an already rich ecosystem.
For instance, StorPool integration with OpenNebula is performed as a new datastore driver in OpenNebula. OpenNebula persistent and non-persistent images are stored in a StorPool cluster, and OpenNebula controls and monitors the StorPool cluster. An important contribution worth noted is on the works, promising to bring LCX support to OpenNebula.
User stories are also good addition to a project credibility. OpenNebula has been around for a while now, but we still are moved by our users from time to time when they decide it is time to announce to the world they use OpenNebula in their infrastructures. For instance, like Teledata did this month.

OpenNebula it turned out to be the most mature and proven Cloud-Stack available – lacking of unnecessary complexity or unneeded overhead.

And it is also nice to see how OpenNebula is being recognised as a solid alternative to commercial virtualization software. In this case, as an alternative to vCloud Director.
OpenNebula API is also being consumed by other components of the ecosystems to create amazing things like automated power management on opennebula based infrastructures, like the new release of CLUES.

Winter is over, Spring is here, and everything is blossoming. And yes, that includes OpenNebula features! The team is busily working on the upcoming 4.14 OpenNebula release, as usual following the roadmap driven by its users, via feature request or even the Fund a Feature program.
OpenNebula 4.14 will add an exciting new snapshot management feature, that will let perform disk snapshots and maintain a history of them. The initial support would be only for Ceph, as it is our storage backend of choice (have you read our reference architecture? now is the chance!)

Sunstone is undergoing a major refactor, since its structure has been left untouched for far too many releases. We are proud to say that now all the components of OpenNebula have clean code and best programming practices! Of course everything has room for improvement, and we did our best in this release for your favourite cloud web interface. Adding new features and polishing the interface is going to be easier than ever now, so expect a big boost in Sunstone for future releases.

A long awaited featured, widely demanded by users, was related to datastore maintenance. Migrating running VMs from one system datastore to another, in order to take offline one datastore or simply to free some space from it will be possible in the upcoming 4.14 release. Rejoice cloud admins!

Image resizing has also been in our backlog for too long, and finally we found the needed resources to develop it. We think this is a very important feature for OpenNebula users and admins, try it out and let us know if this is what you were looking for.

4.14 will have a plethora of new features and improvements, like an improved fault management with the inclusion of new VM state transitions (no VM left behind), improvements in the network context management (more flexibility at the time and place of defining network attributes, … . Make sure you try out the beta release, due in a few weeks.

Community

We love our community. Seriously. Keep it up guys. Want a taste? Check this excellent contribution, detailing the needed steps to create an OpenNebula marketplace image. And when we say detailing, we really mean it. Great post! Also, a great contribution itself to the marketplace! A VyOS image for OpenNebula to achieve complex network topologies for your VM services.

We are very excited about uCloud, Unity Technologies new OpenNebula cloud. uCloud is a state of the art cloud, with authentication and network federation linking three different datacenters based on SoftLayer bare metal, configured for cloud bursting and prepared to scale to support thousands and even millions of users as Unity Technology requires. Read more details on this post we prepared to show the world what can be achieved in little time with OpenNebula, and also in the post the gentle folks at unity have prepared, called Agnostic Cloud Management (we like!).

Fun is always welcome in our community. The team choked in laughter after seeing this tweet from Carlo Daffara (kudos to your friends).

The Barcelona OpenNebula user group is very active, spreading the ONE word this month in the Suoders event, with interesting talks around the technology.

Serious matters are welcome as well. Our Terradue partners gave this talk at the EFIConf15 on Hybrid Cloud Strategy. Worth going through the slides.

What is the best way to move out of Amazon Web Services (AWS) or other public cloud services?

Well, according to iSpot.tv the answer is OpenNebula. Learn the reasons and the approach taken by them in this article.

The community is always contributing back. This month, it provided for instance gems to make OpenNebula a provider for Vagrant, and daemon for getting monitoring data from OpenNebula’s XML-RPC API and storing them to InfluxDB. Also, a very interesting Elastic load-balancing & high-availablitY Wired network Architecture. It comes packed with features, so if you are looking for complex network set ups is a must read. Moreover, a new version of knife plugin for OpenNebula is also available thanks to Megam.

A beta release of CLUES (energy management system for Cloud infrastructures) that supports OpenNebula was also released this month.

OpenNebula Newsletter – April 2015

This Newsletter contains the most worthy developments and events of the OpenNebula project and the community during this last month, and the plans for the upcoming months.

Technology

An important milestone was reached this month with the publication of the Open Cloud Reference Architecture for Basic and Advanced cloud deployments. This Reference Architecture has been created from the collective information and experiences from hundreds of users and cloud client engagements. Besides main logical components and interrelationships, the document describes software products, configurations, and requirements of infrastructure platforms recommended for a smooth OpenNebula installation.

A maintenance release for Cotton Candy,4.12.1, was released this month by the OpenNebula Team. This release comes with several bug fixes found after the 4.12 release. These bug fixes covers different OpenNebula components, like for instance the scheduler, the Cloud View self service portal, Sunstone web interface, OpenNebula Core and several drivers (VM, Auth, Network). Besides the bug fixes mentioned above, 4.12.1 includes several improvements, like the ability to have VNC capabilities imported from vCenter VMs, a logrotate script for OpenNebula logs and, specially, the scheduler has been revisited to cope with large XML files. Now OpenNebula instances are able to manage even more VMs!

Also April saw the release of a new stable version of vOneCloud, the open replacement of vCloud to cloudify vSphere infrastructures. vOneCloud 1.4 comes with outstanding new features for vCenter resource management, like for instance the inclusion of Showback capabilities. The VDC model has been revisited to enable resource sharing easily among different groups, as well as the interfaces, in order to smooth the workflow of importing vCenter resources. The main highlight though is the addition of multi-vm management capabilities, enabling the management of services, including the ability to set up elasticity rules to automatically increase or decrease the number of nodes composing a service. vOneCloud is zero intrusive, try it out with without the need to commit to it!

Community

Technical posts are definitely our sort of thing. And if they come as detailed and rounded as this amazing piece showing how to install OpenNebula on HA with Ceph and IPoIB in CentOS, the better. Check it out for a awesome script laying out all the steps needed to reproduce this setup. Another example is this excellent post about securing noVNC connections for Sunstone, with detailed explanation on how to create your own CA for VNC connections.

In depth analysis of the OpenNebula technology by third parties is a great way to promote OpenNebula, giving users leeway to choose among the IaaS technology that better fit their needs. This blog post by OlinData is a great example.

Our community is always giving back, and that is the spirit of open source. For instance, people sharing his work to make other people’s life easier, is a great example of the health of OpenNebula community. This new addon enabling the integration of OpenNebula and StorPool broads the integration capabilities of OpenNebula. Also important this example of a nodejs boilerplate to interact with OpenNebula. Thanks!

As you may know, OpenNebula is participating in the BEACON project, flagship European project in federated cloud networking. You can check the profile of OpenNebula Systems in the project blog.

We run on feedback. Seriously, it is never enough. If you are doing an OpenNebula deployment we want to hear from you! As they say, through thick and thin. Have you just installed a Windows 10 VM using OpenNebula?. We want to hear from you!
