OpenNebula Newsletter – July 2014

We want to let you know about what we are up to with the main news from the last month regarding the OpenNebula project, including what you can expect in the following months. This month’s newsletter is slightly overdue because the team has been 100% dedicated to the release.

We have created a new user survey that will take you only 5 minutes to complete. As an open-source community, it is very important for us to have information about your deployment. Doing so you will have influence over the project and software direction, and will help us improve the support for most demanded infrastructure platforms and configurations.

Technology

This past month, the OpenNebula team had only one, well defined focus: a new stable release. After one beta version, the team is very proud of the release of OpenNebula 4.8, codenamed Lemon Slice. This release brings significant improvements in different aspects. Sticking with our vision of bringing simplicity to cloud management, this release comes with improvements in the recently added Cloud View portal, now with the ability to control flows, as well with a new interface designed for Virtual Datacenter administrators (VDCAdmin View).

The hybrid model has been one of the principal actors of Lemon Slice. Support for two new public cloud providers (Microsoft Azure and IBM SoftLayer) have been added, widening the range of possibilities to offload VMs in case the local infrastructure is saturated. The hybrid model in OpenNebula enables a centralized management of both local and remote resources for the cloud administrator, and a transparent consumption of these resources by the end user. With these two new additions, OpenNebula is increasing the possibilities to build powerful, robust, cost and performance efficient cloud infrastructures across administrative domains and public cloud providers.

The OneFlow component also has been improved, specially OneGate, making sharing service information among VMs possible. Flows are now easier than ever to build and consume, since details like the virtual network the flow are going to use are defined later by the user, so the administrator doesn’t have to deal with all the possible combinations.

Moreover, Virtual Networks underwent a thorough redesign. Definition of virtual networks are no longer restricted to the fixed and ranged model, but rather they can include any combination of ranges to accommodate any address distribution. Moreover, end users can now reserve a range or IP addresses for their own use at a later time.

Finally, several improvements are scattered across every other OpenNebula component: improvements in quotas management, multi boot available through Sunstone, availability of Windows contextualization packages, new raw device mapping datastore, better Ceph drivers, possibility to clone images across datastores …. ladies and gentlemen, you are in for a treat.

Community

This month has been specially interesting for the movement in the OpenNebula community. Most noticeable, without doubt, is the announcement by two computer industry giants such as Microsoft and IBM of their collaboration with the OpenNebula project.

Microsoft announced in the OSCON 2014 their willingness to tightly collaborate with OpenNebula in order to build Microsoft Azure support within your favourite Cloud Management Platform.

On the other hand, IBM SoftLayer announced in their blog their support for extending OpenNebula hybrid model to be able to outsource VM workload to the SoftLayer cloud. Their interest comes from existing SoftLayer users that seek to complement their public cloud with in house private clouds run by OpenNebula:

Some of our largest customers have already begun using OpenNebula to manage their hybrid cloud environments, so official support for the SoftLayer cloud in OpenNebula is a huge benefit to them (and to us)

Needless to say, we are really excited about this collaborations: building hybrid clouds with OpenNebula is now richer and more powerful than ever.

The community is determined to make the OpenNebula team happy with these little pearls: OpenNebula 4.6.2 cloud running on ARM board of Android TV stick. We want to give a big thanks from here to Carlo Daffara and Vincent V.d. Kussen for their intensive testing, pushing OpenNebula to its limits. Appreciate that! We also appreciate mini tutorials to start using OpenNebula, like this one.

Special thanks are due to the Terradue folks for .NET API to the OpenNebula world. Also, it is very interesting the integration between OpenNebula and Bacula proposed by Rentalia.

Check out the comparative made by Bitergia in the OSCON about the OpenNebula project and its codebase, it is pretty interesting.

We want to thank the community for their feedback, which has proven to be a very important asset turning the beta 4.8 version into the stable Lemon Slice that has been just released. You are the real MVP!

Outreach

As usual, first things first, this year’s OpenNebula Conference will be held in Berlin as well, 2-4 of December, 2014. The final agenda is now available at the conference page. This years will offer the chance to learn how folks from PuppetLabs, E-Post, Deloitte and many other companies are using OpenNebula. If you want to repeat or find out how it is for yourself, save the date and register!

OpenNebula Project Director gave several seminars on cloud computing Berkeley and Stanford this last month. Also, members of the OpenNebula team participated in July in a Centos Dojo in Cologne.

OpenNebula 4.8 Lemon Slice is Out!

The OpenNebula team is pleased to announce the immediate availability of the final version of OpenNebula 4.8, codename Lemon SliceThis release brings significant improvements in different aspects. Sticking with our vision of bringing simplicity to cloud management, there are improvements in the recently added Cloud View portal, designed for end users. One significant advantage of the new portal is the ability to control flows, groups of interconnected Virtual Machines that conform a service. Based on this Cloud View, a Virtual Datacenter administrators view has been included (VDCAdmin View), which enables VDC admins to easily manage the VDC users and resources.

An important highlight in this release is the vast improvement made to the hybrid model. Support for two new public cloud providers has been added, widening the range of possibilities to offload VMs in case the local infrastructure is saturated. The hybrid model in OpenNebula enables a centralized management of both local and remote resources for the cloud administrator, and a transparent consumption of these resources for the end user. With these two new additions, namely support for Microsoft Azure and IBM SoftLayer, OpenNebula is increasing the possibilities to build powerful, robust, cost and performance efficient cloud infrastructures across administrative domains and public cloud providers.

The OneFlow component also has been improved, specially OneGate, making sharing service information among VMs possible. Flows are now easier than ever to build and consume, since details like the virtual network the flow are going to use are defined later by the user, so the administrator doesn’t have to deal with all the possible combinations. Moreover, Virtual Networks underwent a thorough redesign. Definition of virtual networks are no longer restricted to the fixed and ranged model, but rather they can include any combination of ranges to accommodate any address distribution. Moreover, end users can now reserve a range or IP addresses for their own use at a later time.

Finally, several improvements are scattered across every other OpenNebula component: improvements in quotas management, multi boot available through Sunstone, availability of Windows contextualization packages, new raw device mapping datastore, better Ceph drivers, possibility to clone images across datastores …. ladies and gentlemen, you are in for a treat.

This is a stable release and so a recommended update. It incorporate important improvement since 4.6 and several bug fixes since 4.8 Beta. 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. 

As usual OpenNebula releases are named after a Nebula. The Lemon Slice nebula (IC 3568)  is a planetary nebula that is 1.3 kiloparsecs (4500 ly) away from Earth in the constellation of Camelopardalis. It is a relatively young nebula and has a core diameter of only about 0.4 light years.

The new features for Cloud View and VDCAdmin View introduced in OpenNebula 4.8 were funded by Produban in the context of the Fund a Feature Program. The new feature that redefined virtual networks in OpenNebula 4.8 were funded by BlackBerry in the context of the Fund a Feature Program.

Technology

OpenNebula 4.8 is steadily approaching the feature freeze phase, to start the certification process. The OpenNebula team is pretty serious about delivering a beta version of your favourite Cloud Management Platform in a couple of weeks!

This release will polish past features as well as address those left aside in OpenNebula 4.6 Carina. The main focus is twofold. On the one hand, OpenNebula 4.8 is going to address simplicity. OpenNebula is already by far in a unique position among its peers in simplicity: simple to install, simple to configure, simple to use. It is indeed one of the design principles behind OpenNebula, as explained in this post about the OpenNebula vision. The team is decided to keep this simplicity and to extend it. A good example of this is the extension of the Cloud Admin view, with support now for vDC administrators (see below a sneak peek), intended to make Virtual Datacenters easy to manage and consume. Check out the complete list of issues the team is working on for this upcoming release.

On the other hand, OpenNebula 4.8 will bring an important improvement to the hybrid model. Aside from the possibility to outsource VMs to Amazon EC2, this new release will bring the ability to manage VMs in both IBM SoftLayer and Microsoft Azure. We are excited to be collaborating with these two great companies. You can check here the announcement in the SoftLayer blog of the integration, and here is the branch with the prototype integration. The same plan applies to Microsoft Azure, a partnership will be announced soon and a prototype’s code is already in the OpenNebula repository.

Also, and as part of our commitment with the latest stable version, OpenNebula 4.6.2 was released. This release comes with several bug fixes found after the latest release, the one worth highlighting being the security vulnerability in Sunstone. Thanks to Dennis Felsch and Mario Hei­de­rich from Horst Görtz Institute for IT-Security, Ruhr-University Bochum for telling us about it. You should upgrade your installation to prevent unauthorised access.

Last, but by far not least, we wanted to point the benefits of running OpenNebula versus vCloud. So if you are evaluating both alternatives to manage your infrastructure, we are sure you will find this post an interesting read. In a nutshell, using OpenNebula leverages existing VMware infrastructure, protecting IT investments, and at the same time avoids future vendor lock-in, strengthening the negotiating position of the enterprise.

Community

Feedback from the community has proven to be critical, specially this last month thanks to the vulnerability discovered by folks at Horst Görtz Institute for IT-Security, Ruhr-University Bochum. This feedback was crucial in releasing OpenNebula 4.6.2.

The community also excels at providing new and better ways to manage an OpenNebula cloud. This past month, a new plugin for Knife (a command-line tool that provides an interface between a local chef-repo and the Chef server) was released by our friends at Megam.

OpenNebula is proving steadily as a very good solution for hosting infrastructures. We traveled to Zagreb, Croatia, to be part of the presentation of the new OpenNebula cloud built by AVALON hosting. A fine press release with the CEO of Avalon, the IBM director of Croatia, and Microsoft MVPs, as well as members of the OpenNebula team. Also, folks from HostColor have announced this past month a new datacenter in Indiana running OpenNebula.

It is very important to keep the add-ons catalog up to date, that’s why we deeply appreciate keeping them working with the latest versions of OpenNebula, like David Macleod did this month with the Infiniband (SR-IOV devices) support.

It is very pleasing as well to see that OpenNebula goes a long way into cloud computing research. Guys at MIMOS, the Malaysian national R&D center, are basing their cloud infrastructure in OpenNebula, using Ceph as the storage backend.

We are very proud of the OpenNebula community, as well as very happy to see that is a very healthy and supportive one, as proven by it’s ever growing population.

Outreach

As usual, first things first, this year’s OpenNebula Conference will be held in Berlin as well, 2-4 of December, 2014. If you want to repeat or find out how it is for yourself, save the date! The Call for Papers and early registration prices are open until the 15th of July, don’t say we didn’t told you!

Last month we organised two successful OpenNebula TechDays in both US coasts. We had the chance to share new features of OpenNebula 4.6 with the attendees and have them build a fully working private cloud in just a matter of hours, as well as interesting talks, ranging from PaaS solutions based on OpenNebula: Megam – Cloud orchestrator for OpenNebula, open hardware initiatives which are a great match for OpenNebula: OCP Open Rack, the renowned distributed object-store: Ceph for Cloud and Virtualization environments and more use cases. We want to give a big thanks to the hosts: TransUnion|TLOxp and Hyve Solutions for their amazing hospitality, organization and making these events a success! Upcoming TechDays include Timisoara in September and Barcelona in October, and they will be collocated with the CentOS Dojo.

Also, hybrid cloud support will be addressed, with two new plugins on the works. A partnership with IBM/SoftLayer has been announced this last month, and a prototype to manage SoftLayer Virtual Guests using OpenNebula is on the works. The same plan applies to other leading cloud provider, a partnership will be announced soon and a prototype will be ready shortly! Good news for the community, more choice to the cloud users and administrators. And did we say relentless? More partnerships and more public cloud provider support are being crafted ….

Meanwhile, and as part of our commitment with the latest stable version, OpenNebula 4.6.1 Carina was released. This release (4.6.1) comes with several bug fixes found after the latest release, namely bug that prevented VM monitoring information purge (which increased exponentially the disk usage in the OpenNebula front-end) and a Xen related bug affecting VNC. Moreover, OpenNebula 4.6.1 brings a new long overdue feature to the table: accounting information in Sunstone!. Isn’t it pretty?

Two new versions of the excellent Addon, AppMarket 2.0 and AppMarket 2.0.1 were released. These releases are part of the AppMarket 2.0.x series, which extends the AppMarket functionality by adding a new set of features that enables the management and processing of OVA files. A new component AppMarket Worker is introduced, which handles the OVA package treatment (download, unpack, OVF parsing) and image format conversion. This release also features a new API, a new simplified import dialog, a new AppMarket interface via Sunstone, and handles VMware and VirtualBox OVAs.

Community

OpenNebula community has been very active, producing high quality feedback to iron out the wrinkles in OpenNebula 4.6. This feedback was crucial in releasing OpenNebula 4.6.1, which fix bugs present in the first Carina version. It seems that the upgrade process is streamlined (as stated here,here and here ;) ), and overall the feedback on the new version was very positive!

It is also worth highlighting the smallest box containing a full fledged OpenNebula cloud. It is small, it is powerful, it is pretty: meet the smallest Cloud Weavers!.

Also, this kind of feedback from the OpenNebula users makes us blush and happy, and willing to keep OpenNebula in the right track!

A very cool integration between OpenNebula and The Foreman has been developed by the guys at Netways. It can be used to deploy virtual machines within OpenNebula using the Foreman interface which configures DNS,DHCP,PXE,Puppet and so on as well. The functionality is covered by using and extending the ruby fog library.

It is also very nice to find out that the European Grid Infrastructure counts with OpenNebula in their plans involving cloud technologies and infrastructures ;)

OpenNebula Newsletter – April 2014

We want to let you know about what we are up to with the main news from the last month regarding the OpenNebula project, including what you can expect in the following months.

Technology

After one beta and one RC release, OpenNebula 4.6 Carina was released. With Carina the OpenNebula team has started a journey to deliver a more intuitive and simpler provisioning experience for users. Our goal is to level the final user usability with the system administration and operation ones. So, sing along with us, simplicity is the key!

OpenNebula Carina brings a new cloud provisioning portal with a simpler, clean and intuitive design. This view ensures a minimal and utterly simple portal to consume cloud resources. All the clutter is out of the way to make the experience as pleasant as possible. The Sunstone graphical interface has also been tweaked to help implement common cloud admin workflows and improved in order to support the new Marketplace version, which makes even easier for a user to get a virtual application up and running.

This release also consolidates a provisioning model based on Virtual Data Center (vDC), offering an integrated and comprehensive framework for resource allocation and isolation. Another important new feature has taken place in the OpenNebula core. It has undergone a minor re-design of its internal data model to allow federation of OpenNebula daemons. With OpenNebula Carina your users can access resource providers from multiple datacenters in a federated way.

Also, a release candidate of the AppMarket 2.0 was released. This release extends the AppMarket functionality by adding a new set of features that enables the management and processing of OVA files. A new component AppMarket Worker is introduced, which handles the OVA package treatment (download, unpack, OVF parsing) and image format conversion.

Another advancement in contextualization was brought on by the OpenNebula team, this time in Windows contextualization. This new development adds the possibility to add users to Windows guests within Virtual Machines, enable remote desktop, enable ping, update the hostname, etc; using the OpenNebula contextualization mechanism.

Some of the Carina features and the new features in AppMarket 2.0 have been sponsored by Produban in the context of the Fund a Feature program.

Community

OpenNebula community has been especially productive this last month. The mailing list was flooded with feedback on the beta and release candidates of OpenNebula 4.6 Carina, which is always a plus in polishing a release and adjust it to people needs.

It is worth highlighting oneInsight, a visualization addon for OpenNebula that allows users to have a graphical insight of the load of managed hosts. We all love charts, they certainly make administrator lives easier! Thanks Rodrigue Chakode for this great Addon.

Another great addition to the OpenNebula software ecosystem allows the integration of OpenNebula as a provider for salt-cloud. Check it out, it’s really neat.

OpenNebula 4.6 Carina is Out!

The OpenNebula team is pleased to announce the immediate availability of the final version of OpenNebula 4.6, codename CarinaThis release introduces important improvements in several areas. The provisioning model has been greatly simplify by supplementing user groups with resource providers. This extended model, the Virtual Data Center, offers an integrated and comprehensive framework for resource allocation and isolation. Another important new feature has taken place in the OpenNebula core. It has undergone a minor re-design of its internal data model to allow federation of OpenNebula daemons. With OpenNebula Carina your users can access resource providers from multiple datacenters in a federated way.

With Carina the OpenNebula team has started a journey to deliver a more intuitive and simpler provisioning experience for users. Our goal is level the final user usability with the system administration and operation ones. OpenNebula Carina brings a new cloud provisioning portal with a simpler, clean and intuitive design. The Sunstone graphical interface has also been tweaked to help implement common cloud admin workflows and improved in order to support the new Marketplace version, which makes even easier for a user to get a virtual application up and running.

Finally, some other areas have received the attention of the OpenNebula developers, like for example a better Gluster support through libgfapi, improved access to large pools pagination, or optionally limit the resources exposed by a host, among many others are included in Carina.

This is a stable release and so a recommended update that incorporates several bug fixes since 4.6 RC. We’ve done our best to keep compatibility with OpenNebula 4.4, so any application developed for previous versions should work without effort. In any case, 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. 

Thanks 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.

As usual OpenNebula releases are named after a Nebula. The Carina Nebula (NGC 3372) is one of the largest nebulae the sky. It can only be seen from the southern hemisphere, in the Carina constellation.

More information

OpenNebula Newsletter – March 2014

We want to let you know about what we are up to with the main news from the last month regarding the OpenNebula project, including what you can expect in the following months.

Technology

With OpenNebula 4.6 Beta released, the team is working full throttle ironing out wrinkles: fixing bugs, polishing the interface, prepping the documentation, updating related components and applications, etc. It is a lot of work, but we want our users to experience a migration as smooth as possible.

One of the main contributions of this new release is a big boost to the provisioning model. Besides the Sunstone interface facelift, including tweaks to help the user workflow, there has been a number of provisioning ideas developed in this release. For instance, Sunstone integration with marketplace has also been improved in order to support the new AppMarket version, which makes even easier for a user to get a virtual application up and running. Moreover, the provisioning model has been greatly simplify by supplementing user groups with resource providers. This extended model, the Virtual Data Center, offers an integrated and comprehensive framework for resource allocation and isolation.

The latest addition to the provisioning model improvement is the new provisioning view for cloud end users. This view ensures a minimal and utterly simple portal to consume cloud resources. All the clutter is out of the way to make the experience as pleasant as possible. Give it a spin!

BjrE8KmIcAE93TN

The other significant features that will be present in OpenNebula 4.6 includes the ability to achieve a federation using OpenNebulas (yes, plural is coming!) at different datacenters. Check out the screencast on partitioning clouds with vDCs to get a feel on this new functionality. Also, 4.6 will feature the ability to import OVAs into OpenNebula via AppMarket, and will be a complete translation and import of all the resources defined in the OVA: disks, capacity, network, etc. Other aspects that are being revisited are storage backends, virtual networking, datastore, image and VM management and Sunstone. You can find a comprehensive list here.

Some of the above features have been sponsored by Produban in the context of the Fund a Feature program.
Another technology contribution by OpenNebula members is summarise in this post about integrating puppet and OpenNebula: Automatic configuration of VMs with Puppet. Moreover, integration with GlusterFS (a distributed filesystem with replica and storage distribution features that come really handy for virtualization), was also addressed in the Native GlusterFS Image Access for KVM Drivers post.

Community

This month the community was as engaged as ever. We would like to give a big “thank you” to all the OpenNebula users that gave as feedback about the beta version of OpenNebula 4.6. The final release will be more robust due to you!

Our friends at BIT (this month they hosted the very first OpenNebula TechDay, check the Outreach section of this newsletter ;) ) wrote a very long and flattering (cheers!) post stating their experiences with OpenNebula. We would like to highlight in this newsletter the following excerpt:

The OpenNebula way of developing software is open, and user focused, The “voice” of the community really matters. The cliche “software made with and for the community” really applies here. If users get (positive) feedback about their input they feel appreciated and be more “connected” to the project. The “atmosphere” on the mailing list is friendly and open. No flame wars, or negativism here, so it keeps users “in” instead of pushing them away.

So we blush! We are glad that our users feel this atmosphere, which is the main driver of the OpenNebula project ;)

Folks at CloudWeavers build this slick portable DC based on OpenNebula. Awesomely pretty!

Experiences at CeBIT 2014

Last week we participated at CeBIT 2014. In the unlikely case you are not familiar with CeBIT, it is the world’s largest and most international computer expo (wikipedia’s words, not ours ;) ). We were demoing the latest features in OpenNebula 4.6, as well as hanging around the booth of the active and community engaged Netways, we would like to thank them for the support. We’ve also featured a talk in the Open Source Park, about the history of the OpenNebula project.

All in all, a very good experience. CeBIT is a very interesting place to meet with people who are looking for what you offer, so if you are planning to attend next year and need for an outstanding Cloud Management Platform (aka OpenNebula), see you in Hannover!
