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.

OpenNebula Newsletter – December 2015

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

The OpenNebula team is waving goodbye to 2015. This year the OpenNebula project has turned 8 years old, and we are proud to see the matureness of the software and how is helping people around the world to create private and hybrid production clouds. Happy new year dear community!

Technology

After the release of a new maintenance release for Great A’Tuin, the 4.14.2, with several bugfixes as well as new improvements in Sunstone and vCenter integration; the team has set the next milestone in the upcoming OpenNebula 5.0

As you may know, in the OpenNebula project we value our users feedback. Since 5.0 is going to be a very important milestone in the project, we wanted to know your opinion before defining the roadmap. For this reason, we did a survey to gather your opinion regarding OpenNebula and its features. We received a huge amount of feedback, which is proving immensely values to shape OpenNebula according to its user needs. Thanks again for your engagement with the project.

One of the great assets of OpenNebula is its customization capabilities. Its modular architecture widens the integration range with different datacenter components. We wanted to flexibilize Sunstone as well, to offer the end users the functionality emerging from such integrations, and thus we have written a Sunstone development guide. We are sure this will open the door to richer clouds based on OpenNebula.

We know that creating images for any cloud can be a hard task. In order to lower this barrier to allow for a wider range of applications available in all OpenNebula clouds, we created a guide to aid customizing images based on libguestfs. If you are building or operating an OpenNebula cloud, it may be worth checking.

Community

Producing quality ecosystem components for OpenNebula is a great addition to the project. But if you top it with an excellent post describing the new component and how it interacts with and what value bring to OpenNebula, then you deserve a big thumbs up! In this case, we are talking again about our friends at Universidad Politécnica de Valencia and their recent addition, CloudVamp, which adds automated oversubscription and dynamic memory elasticity for OpenNebula. Don’t remember the guys from Universidad Politécnica de Valencia? They are the authors of the ONEDock, an exciting approach to Docker integration.

A new addon component for the ecosystem brings ZFS support for OpenNebula clouds. This is a great addition that we are sure will interest the OpenNebula users.

Another great, great addition to the OpenNebula capabilities is this LXC addon, which this month enters officially into its first stable release. Great job guys!.
As usual, we blush with our community comments. This time, the feature to blame is the easiness of deployment of an OpenNebula cloud. We work hard towards this goal, and it is very rewarding to learn that this is not a work that is taken for granted.

In case you missed it, we wanted to highlight this excellent post by Florian Hettenback, analyzing the OpenNebula characteristics. We do not speak german, but we liked what we understood from the translation.

As usual, we want to mention the efforts the community undergoes to maintain the ecosystem up to date. Way to go! We really appreciate it. This month we learned about a new version of the OCA (OpenNebula Cloud API) python binding and the release of version 0.4 of the OpenNebula-Foreman integration. Thanks!.

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.

Maintenance Release – OpenNebula Great A’Tuin 4.14.2

The OpenNebula team is proud to announce a new maintenance release of OpenNebula 4.14.2 Great A’Tuin. This release comes with several bug fixes found after the 4.14 release. These bug fixes covers 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.

Besides the bug fixes mentioned above, 4.14.2 includes several improvements:

If you haven’t had the chance so far to try OpenNebula 4.14, now is the time to download and install OpenNebula 4.14.2 Great A’Tuin. The team have also updated the Sanboxes if you want to take Great A’Tuin for a test drive.

As as highlight, find below a screencast describing the new import feature that allows importing VMs running in public cloud providers, vCenter, XEN and KVM environments to be managed through OpenNebula.

The team is working on a new version of the Marketplace compatible with 4.14.2, as well as a new set of context packages.

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.

vOneCloud 1.8 Released! Take vSphere to the Cloud

We want to let you know that OpenNebula Systems has just announced the availability of vOneCloud version 1.8.

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. Coming from functionality present in 4.14 we found:

  • Import VMs from public clouds. vOneCloud 1.8 introduces the management of VMs not launched by vOneCloud in either Amazon EC2, Microsoft Azure and IBM SoftLayer.
  • Keep  VM disks after deletion. A new attribute will instruct vOneCloud on leaving or deleting the VM disks when they finish their lifecycle.

Features related with the vCenter driver not yet present in any OpenNebula release (these will be part of next OpenNebula release):

  • Pagination added to vCenter import dialog. In large scale deployments, this will aid in the importation of large numbers of VM Templates and Networks.
  • Support for VMware Guest Customization. At the time of creating or modifying an imported VM Template, it is now possible to associate a Guest Customization profile to configure guest OS parameters such as the computer name, network settings, setting and expiring the administrator/root password, SID change for Windows Operating systems, and so on.
  • Show all the IPs from a VM in Sunstone. Both for imported and newly created VMs, all the IP addresses reported by the guest OS via the VMware tools are retrieved by vOneCloud and presented in Sunstone.
  • Append name to “one-*” name in vCenter display name. VM Name as shown in vOneCloud is appended in vCenter VM name for easier VM tracking.
  • Imported resources suffixed with their source cluster name. This feature aids in the resource identification in the vCenter portal by mapping it to the vOneCloud representation name.
  • Multi cluster VM Template definition. Create vOneCloud VM Templates that reference more than one vCenter VM Template in different vCenter clusters.

vOneCloud Control Panel has also been extended in this release to allow for further customizations:

  • Enable SSH. To easily allow console access to the vOneCloud appliance.
  • Enable SSL. To enable the secure access to the vOneCloud appliance web interface (Sunstone) using the SSL protocol.

Moreover, a new documentation category starts with vOneCloud 1.8 to explain advanced customizations to the appliance that are not performed through the Control Panel. The fist introduced advance customization refers to rebranding, to replace the logos in the Sunstone interface.

The above features and components add to the already present ability to expose a multi-tenant cloud-like provisioning layer through the use of 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 virtualised infrastructures, leveraging advanced features such as vMotion, HA or DRS scheduling provided by the VMware vSphere product family.

vOneCloud is zero intrusive (although it fully manages the life cycle of VMs), try it out without the need to commit to it. If you happen (as strange at that may be!) to don’t like it  you can just remove the appliance.

OpenNebula Systems will run a booth at VMworld 2015 Europe in Barcelona on October 12-15 where they will demo the new version.

OpenNebula Newsletter – September 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 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.

Outreach

OpenNebula 4.14 ‘Great A’Tuin’ is Out!

The OpenNebula team is pleased to announce the immediate availability of the final version of OpenNebula 4.14, codename Great A’Tuin. One of the main focus of this release has been the Sunstone interface, which 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.

Screenshot from 2015-09-25 13-01-56

To support HPC oriented infrastructures based on OpenNebula, 4.14 enables the consumption of raw GPU devices existing on a physical host from a Virtual Machine. 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. 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, enabling applications to get the performance boost of the direct access to a GPU card.

OpenNebula users managing vCenter infrastructures will also benefit from this upgrade. The workflow of the VM importing feature has been greatly improved through Sunstone, making it easier to import your existing workload into OpenNebula. Moreover, 4.14 adds the possibility to instruct OpenNebula whether or not it should save the disks, protect your users against accidental data lost! Last, but not least, a contextualisation improvement now allows to directly pass scripts to be executed in boot time to vCenter VMs, increasing the flexibility in VM customisation from OpenNebula in vCenter.

Also new in 4.14 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.

Other very interesting new features made their into 4.14. A non-exhaustive list follows (check the full list of changes in the development portal):

  • 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
  • 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

This is a stable release and so a recommended update. It incorporates important improvement since 4.12 and several bug fixes since 4.14 Beta2. Be sure to check the compatibility and upgrade guides. We invite you to download it and to check the QuickStart guides, as well as to browse the documentation, which has also been properly updated. If you want to take OpenNebula 4.14 for a quick test drive, take a look at the different SandBoxes.

Several organizations have sponsored the project through the Fund a Feature Program:

The OpenNebula project would like to thank these organizations and the community members and users who have contributed to this software release by being active with the discussions, answering user questions, or providing patches for bugfixes, features and documentation.

New Pricing Plan for Support Subscriptions

OpenNebula Systems, the company behind the OpenNebula project, have just announced a new pricing plan for OpenNebula Support Subscriptions. With the new plan, the aim is to be as easy to work with as possible, including complete transparency about pricing, no complicated plans, lower cost, and a maximum cost per OpenNebula instance (“zone”) that is achieved beyond 50 servers in Xen/KVM clouds and 5 vCenter instances in VMware clouds. This avoids having to track and manage individual server or vCenter instance count enabling you to take advantage of the elastic nature of cloud, especially as you scale your infrastructure.

Many of our existing customers will see a reduction on their next renewal. You can now buy a Basic Support Subscription for a single OpenNebula instance and an unlimited number of servers, VMs, CPUs and cores for only €12.000 euros ($15,000 in USA).

OpenNebula is completely vendor-neutral and without hype, with a strong focus on real-life needs, developing the best technology, and serving users. We love open-source and take pride on being  an open-source company. There is only one completely free, fully open source, OpenNebula software. We do not develop proprietary extensions that lock you in. We hope the new pricing plans make it even simpler to setup your perfect open cloud environment with commercial support, based on your favourite Cloud Management Platform!

Our support subscriptions bring many benefits but the main one is that they help support the OpenNebula open-source project. We want to thank all our customers for their confidence in us.

Stay tuned and as always, let us know what you think!

OpenNebula 4.14 ‘Great A’Tuin’ Beta2 is Out!

The OpenNebula project is proud to announce the release of OpenNebula 4.14 ‘Great A’Tuin’ Beta2. This Beta release introduces features not present in Beta1, like like for instance better support for Qcow2 and GPU support for VMs.

To support HPC oriented infrastructures based on OpenNebula, 4.14 also enables the consumption of raw GPU devices existing on a physical host from a Virtual Machine. 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. 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, enabling applications to get the performance boost of the direct access to a GPU card.

OpenNebula users managing vCenter infrastructures will also benefit from this upgrade. The workflow of the VM importing feature has been greatly improved through Sunstone, making it easier to import your existing workload into OpenNebula. Moreover, 4.14 adds the possibility to instruct OpenNebula whether or not it should save the disks, protect your users against accidental data lost! Last, but not least, a contextualisation improvement now allows to directly pass scripts to be executed in boot time to vCenter VMs, increasing the flexibility in VM customisation from OpenNebula in vCenter.

There are many other improvements in 4.14 (check the full list of changes in the development portal, or alternatively, the post on 4.14 beta1 release):

  • ceph and qcow2 disk snapshotting
  • 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
  • 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

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.
