TechDay in Prague March 7th

In less two weeks we are going to have our first TechDay this year. We want to thank our friends at CESNET for organizing it!

This time the TechDay is a little bit different and instead of talks we will have an open session where people can ask questiosn on how to use OpenNebula. Experienced users from CESNET will answer your questions. We are still having the tutorial in the morning for people that never used OpenNebula.

If you want to know more head to the TechDay page or head directly to the registration page, it’s free!

OpenNebula Newsletter – January 2017

The OpenNebula newsletter brings the latest news, advances in the technology, community work and the dissemination efforts carried out by the OpenNebula project this month.

We bring some big news this month! There will be two OpenNebulaConf editions this year, one in US and the other in Europe. The US edition will take place on June 19-20 in Cambridge, Massachusetts, and the european edition will be held in Madrid, Spain, on October 23-24.

Looking for a job in cloud computing? We are still looking for Cloud Developers and a Community Specialist to join our team, check this for more details.

Technology

A new maintenance release of OpenNebula 5.2 was released, OpenNebula 5.2.1. This release brings minor improvements in the SDRS clustered vcenter datastores, vlan management and the ec2 driver set. Also, a significant number of bugs have been fixed in 5.2.1.

The team is grooming OpenNebula 5.4. A lot of new features are being worked upon, with a focus on the vCenter integration. Besides all the improvements described in our December newsletter, we’ve decided to introduce a very demanded feature in the vCenter drivers, the ability to create linked clones from OpenNebula. A linked clone is a copy of a virtual machine that shares virtual disks with the parent virtual machine in an ongoing manner. This conserves disk space, and allows multiple virtual machines to use the same software installation. This requires a special VM Template with snapshots included, the import process will allow to change the VM Template to meet this requirement or alternatively clone it and change it so it does. Nice and simple! You can check the full planned change log in the development portal.

New contextualization packages were released as well. new versions of the OpenNebula contextualization packages for Linux (ver. 5.0.3) and Windows (ver. 5.2.0). For Linux, this is mainly a bugfix release with 2 significant improvements. For Windows, this is a very first release, newly distributed as the MSI package.

And last, but by no means least, vOneCloud 2.2 is already out! This release brings the improvements of the latest Excession release to the appliance. 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 don’t like it (as strange at that may be!) you can just remove the appliance.

Community

This last month we announced officially the OpenNebula Champion Program. Champions are passionate volunteers who work to connect, teach and spread OpenNebula. They represent OpenNebula and help to teach and spread OpenNebula, throughout the world.

vOneCloud is solving a big problem in the self provision of VMware resources. An excellent article in The Register beautifully lays out the simplicity it introduces in a sometimes overbloated paradigm. Being named as one of the five open source tools admins need to know is an honor.

It is a real luxury to count with excellent members (and Champions!) in our community. This extra testing makes OpenNebula more robust and more production ready, and we deeply appreciate that. We also get to receive outstanding contributions like this one, enhancing the virtual router with Load Balancing features. Amazing, big thanks from the team!

And keeping the ecosystem up to date is not small task either, so this update of the Nagios Probes for Monitoring OpenNebula and OCCI is good news.

Outreach

vOneCloud 2.2 Released! Make a Self-Provisioned Cloud on top of vCenter

We want to let you know that OpenNebula Systems has just announced the availability of vOneCloud version 2.2.

This new release of the appliance, based on a tailored version of OpenNebula 5.2.1 Excession to ease the provisioning of resources from vSphere based infrastructures, comes packed with exciting new features. Coming from functionality present in 5.2.1 we found:

  • Support for clustered Datastores, SDRS clustered datastores are now visible in vCenter.
  • Better Sunstone support, with host dropdown option in DS creation and image import.
  • Network monitoring, now vCenter VMs network traffic is accounted for in OpenNebula.
  • Limit VM Network consumption, with specific values available in each of the NICs of a Virtual Machine.
  • More useful vCenter networks import, importing networks with the same name in different clusters is now possible.
  • More useful vCenter datracenter import, importing datastores skips those not associated with any cluster.

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 and self-service portal. 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. If you are building a large-scale cloud, are interested in the federation of multiple cloud instances, hybrid deployments, or want to integrate with third party components, customize the product or manage open source hypervisors, we recommend an installation of OpenNebula.

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 don’t like it (as strange at that may be!) you can just remove the appliance.

OpenNebula Systems will run a booth at VMworld 2017 US in Las Vegas on August 27-31 and VMworld 2017 EU in Barcelona on September 11-14 where they will demo the new version.

And remember… OpenNebulaConfs are vendor-neutral events focused on real-world practices and how to successfully implement open source in your cloud.

We look forward to seeing you in Madrid!

New Contextualization Packages

We are happy to announce new versions of the OpenNebula contextualization packages for Linux (ver. 5.0.3) and Windows (ver. 5.2.0). For Linux, this is mainly a bugfix release with 2 significant improvements. For Windows, this is a very first release, newly distributed as the MSI package.

Linux contextualization contains following changes:

  • User $USERNAME is created, if missing. The user password can be also Base64 encoded in context. variables $CRYPTED_PASSWORD_BASE64 or $PASSWORD_BASE64. Race condition has been also fixed to create the $USERNAME first and contextualize the SSH access later.
  • Refactored code is used to set host and domain names (via $SET_HOSTNAME or $DNS_HOSTNAME context. variables) in a more standard way. Platform dependent scripts were replaced by single unified script. Also, the hostname entry in a local static lookup table (/etc/hosts) is created and even updated on the IP configuration change (PR). Big thanks to Florian Heigl for designing the change request and time spent in testing.
  • Jan Kasprzak provided a patch (PR) for the Red Hat-like systems to disable IPv6 autoconfiguration and by default enable the dual-stack on configured interfaces. This behavior was also fixed for Debian-like systems (PR).
  • C. R. Oldham provided a patch to support growroot with Btrfs (PR).
  • A race condition in run locking was fixed (PR)

Windows contextualization scripts are distributed newly as the MSI package. The source codes archive is still available in case you experience any problems with the package or want to use your own way how to manage the scripts. The package can be installed by double-clicking on the downloaded package icon or from the command line:

msiexec /i one-context-5.2.0.msi

Windows contextualization is started as the Windows service named onecontext (under rhsrvany wrapper). Please remove any existing contextualization (and its startup mechanism) from your virtual machine before installing this package.

You can download the Linux and Windows packages here. Packages are compatible with the OpenNebula versions from 4.6 to 5.2.

OpenNebula 2016: Year in Review

christmas_one_2016We are approaching the end of this year 2016, winter has finally come, and we wish to thank all those individuals and companies that helped with the numerous achievements of OpenNebula throughout the year.

OpenNebula is keeping its momentum, widening its adoption and turning into a very mature product, with more than  9 years of development behind. We like to give a special recognition to the over 1.000 contributors registered in the development portal, who help advance OpenNebula by submitting bug fixes, patches, feature requests, …. We look forward to your contributions to code development!.

Also, we would like to thank Blackberry,  Unity and the Université Catholique de Louvain for funding general interest features that are made available publicly in OpenNebula releases through the Fund a Feature program. The community is certainly in debt with you.

It is always difficult for an open-source project to know who uses its software. So we consider ourselves lucky to know that there are more than 3.500 production OpenNebula clouds connected to our marketplace, with the largest one spanning over 16 data centers with over 300.000 cores. This year a milestone was achieved with more than 180.000 downloads of the OpenNebula packages.

Two major OpenNebula releases were published this year: 5.0 Wizard and 5.2 Excession. Moreover, three maintenance versions were released to fix bugs and polish features. Focus in future release will be centered in the vCenter integration, without neglecting the default hypervisor for OpenNebula clouds, KVM. The plan is to bring vCenter up to speed with the KVM support.

vOneCloud achieved v2.0 this year, an important milestone that allowed to settle a number of features and plan for the future roadmap. Lots of new vCenter related features are present in OpenNebula and will make their way to vOneCloud, specially with the redesign expected in OpenNebula 5.4 of the vCenter integration, that will bring full storage and network manage to the table. vOneCloud exposes a multi-tenant, cloud-like provisioning layer, including features like virtual data centers and a slick self-service portal.

The community has been very active engaged this year 2016. Many contributions in the form of new addons, functionality patches, feedback for future releases, messages in the forum, twitter and so on were delivered in the past 12 months.  You can check these contributions, along with other details about the great progress that we have seen for the OpenNebula project in our monthly newsletters. We are also announcing our new Community Champions Program. An exclusive group of passionate technology and community leaders that help sustain and grow our user base. They represent OpenNebula and work to connect, teach and spread OpenNebula, throughout the world.

This year’s OpenNebulaConf was held again in in Barcelona and featured very interesting keynotes by relevant users like Telefonica or Akamai, among others. It featured 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. You can check our YouTube channel, download the slides from the slideshare account or take a look to the pictures of the conference.  For 2017 we are planning to break down the conference in two instances, one to be held in Europe and another in the US. Yes, our first conference in the US. Stay tuned!

Also this year, members of the OpenNebula team participated in several OpenNebula TechDays around the world. These are full day events to learn about OpenNebula with a hands-on cloud installation and operation workshop and presentations from community. We want to give a warm thank you to all organizations that hosted a TechDay in 2016 for their hospitality: Mimos in Kuala Lumpur, StorPool in Sofia, Rentalia in Madrid, ContainerizeThis in Dallas, C151 Data Centers in Toronto, Harvard FAS Research Computing in Cambridge, BIT.nl in Ede, Netways in Nüremberg and Trinity College Dublin in Dublin. 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.

Finally, we want to highlight the participation in both VMworld Europe and US, where the team were showcasing vOneCloud functionality over vCenter.

Community

We are very happy with the feedback given by the community. OpenNebulaConf 2016 was the perfect place to reunite with all the OpenNebula folks, and to share with them our plans for your favourite Cloud Management Platform.

For instance, we love tweets like this, it helps reminding us why we iterate OpenNebula to give users the smoothest experience.

So far we are happy with @opennebula – much more developer/admin friendly

It is also a joy to learn who is using OpenNebula to build production clouds, and how they are using them. This is a very nice example of a very useful use for an OpenNebula cloud. Having an OpenNebula cloud deployment in the European Space Agency (and, more importantly, knowing about it) is a good kick!.

We also want to give the thumbs up to those kind souls that give us a hand helping newcomers to set up their OpenNebula clouds. It is important to give a warm welcome to people willing to understand OpenNebula and approaching through the user forum, so thanks!

Outreach

If you are new to OpenNebula, one of the best ways of catching up is attending the OpenNebulaConf. You have the chance to meet OpenNebula users with real use cases and production environments, and to solve the doubts you may have about the technology to build private and hybrid clouds. If you are wondering what the OpenNebulaConf looks like, check the post with the material of 2016 OpenNebulaConf. Check out the YouTube channel, download the slides from the slideshare account or take a look to the pictures of the conference.
