OpenNebula 5.4 ‘Medusa’ is Out!

The OpenNebula project is proud to announce the availability of the stable release of OpenNebula 5.4 ‘Medusa’. Medusa is the third release of the OpenNebula 5 series. A significant effort has been applied in this release to enhance features introduced in 5.2 Excession, while keeping an eye in implementing those features more demanded by the community.

As usual almost every component of OpenNebula has been reviewed to target usability and functional improvements, trying to keep API changes to a minimum to avoid disrupting ecosystem components. An important focus has been on the vCenter integration, with an enhanced network and storage management. Also, new components have been added to improve the OpenNebula experience.

A major overhaul has been applied to the vCenter integration. The team decided to go all the way and level the vCenter integration with the KVM support. This means:

  • Full storage management. Non-Persistent images are now supported as well as volatile disks. OpenNebula is now aware of all VM disks and storage quotas can be enforced. Support for linked clones and Marketplace.
  • Full network management. It is now possible to create vCenter standard and distributed port groups and even vSwitches directly from within OpenNebula. You can assign a VLAN ID to a port group created by OpenNebula.
  • Improved monitoring. Up to two orders of magnitude of speedup.
  • An enhanced import process where naming limitations in imported resources has been removed and the ability to enable VNC automatically for Wild VMs.
  • Disk resizing, VM and Templates folder selection when a VM is deployed… and many more changes!

disk_resizing

A new resource, the VM Groups, has been added to implement VM-VM and VM-Host affinity/anti-affinity rules. A VM group is a set of related virtual machines that may impose placement constraints based on affinity and anti-affinity rules. A VM group is defined as a set of Roles. A Role defines a VM type or class, and expressions to the VM Group can be added to define affinity between VM roles, or between VM and hosts. This ensures a dynamic approach to affinity/anti-affinity since new VMs can be enrolled to a particular Role at boot time, after the VM Group has been defined and other VMs added to it.

To top it all, OpenNebula 5.4 brings to the table a native implementation of a consensus algorithm, which enables the High Availability deployment of the OpenNebula front-end without relying to third party components. This distributed consensus protocol provides fault-tolerance and state consistency across OpenNebula services. A consensus algorithm is built around two concepts, System State -the data stored in the database tables- and Log -a sequence of SQL statements that are consistently applied to the OpenNebula DB in all servers-. To preserve a consistent view of the system across servers, modifications to system state are performed through a special node, the leader. The servers in the OpenNebula cluster elects a single node to be the leader. The leader periodically sends heartbeats to the other servers (follower*) to keep its leadership. If a leader fails to send the heartbeat, followers promote to candidates and start a new election. This feature, with support from floating IPs and a proper Sunstone configuration, gives robustness to OpenNebula clouds. This new functionality of distributed system state is also used to implement OpenNebula federation. In both cases (Federation and HA) no support is needed from MySQL to create a clustered DB, so admins can forget about MySQL replication.

There are many other improvements in 5.4, like improved VM lifecycle, flexible resource permissions, life disk resizing, improved Ceph support, enhanced disk I/O feedback, showback cost estimate in Sunstone, flexible IPv6 definition, http proxy support for marketplace, purge tools for the OpenNebula database, resource group isolation, multiple Sunstone improvements (VNC, password dialogs, confirmation dialogs, better vCenter support, persistent labels, usability enhacenents), networking improvements, user inputs in OneFlow and many many more features to enrich your cloud experience. As with previous releases, and in order to achieve a reliable cloud management platform, the team has gone great lengths to fix reported bugs and improve general usability.

This OpenNebula release is named after the Medula Nebula, a large planetary nebula in the constellation of Gemini on the Canis Minor border. It also known as Abell 21 and Sharpless 2-274. It was originally discovered in 1955 by UCLA astronomer George O. Abell, who classified it as an old planetary nebula. The braided serpentine filaments of glowing gas suggests the serpent hair of Medusa found in ancient Greek mythology.

OpenNebula 5.4 Medusa is considered to be a stable release and as such, and update is available in production environments.

The OpenNebula project would like to thank 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.

The VM Groups functionality, the configurable semantics of the VM operations permissions (ADMIN, MANAGE and USE) and the improved VM history functionality were funded by BlackBerry in the context of the Fund a Feature Program. The configurable image persistency setting and the new Non-SLAAC IPv6 Address Range were funded by University of Louvain.

OpenNebula 5.4 ‘MedusaBeta 1 and Beta 2 have been released this past June, and now the team is working at full throttle on stabilizing. Your feedback is of the utmost importance in this regard, so if you have the time please download and test the latest Beta, and let us know about your feedback in the community forum or the development portal.

Medusa is the third release of the OpenNebula 5 series. Almost every component of OpenNebula has been reviewed to target usability and functional improvements, trying to keep API changes to a minimum to avoid disrupting ecosystem components. An important focus has been on the vCenter integration, with an enhanced network and storage management, support for linked clones, disk resizing, save as template functionality (this is a new addition working on Beta2) for vCenter VMs, disk save as functionality, automatic storage scheduling, storage quotas and many more! 5.4 Medusa takes a giant leap forward in vCenter support, bringing it up to speed with KVM VM management.

But there is more! A new resource to implement affinity/anti affinity VM-to-VM and Host-to-Host has been added to OpenNebula, the VM Groups. A VM group is a set of related virtual machines that may impose placement constraints based on affinity and anti-affinity rules.

To top it all, OpenNebula 5.4 brings to the table a native implementation of a consensus algorithm, which enables the High Availability deployment of the OpenNebula front-end without relying to third party components. This new functionality of distributed system state is also used to implement OpenNebula federation. There are many other improvements in 5.4 like improved VM lifecycle, flexible resource permissions, live disk resizing, improved Ceph support, enhanced disk I/O feedback, showback cost estimate in Sunstone, flexible IPv6 definition, http proxy support for marketplace and many more!!

This OpenNebula release is named after the Medula Nebula, a large planetary nebula in the constellation of Gemini on the Canis Minor border. The OpenNebula team is now set to bug-fixing mode. Note that this is a beta release aimed at testers and developers to try the new features, and send a more than welcomed feedback for the final release.

This coming month of July is going to be very exciting as we believe it will set a new top mark on cloud management platform with the release of the stable 5.4 version of OpenNebula!

Community

So it seems that the OpenNebula community hasn’t yet gone into vacation mode. This month it features outstanding contributions which enrich greatly the OpenNebula ecosystem.
The first highlight we want to make is this nifty android vulnerability scanner using OpenNebula and android emulators. The scanner leverages OpenNebula VM management capabilities to provision VM emulators and then uses ADB to connect and start the analysis. Very good work!

Next, a new version of the integration component for OpenNebula and cloudkeeper has been released. Cloudkeeper read image lists provided by EGI AppDB, parse their content and decide what cloud appliances should be added, updated or removed from managed cloud. During the addition and update cloudkeeper is able to download an appliance’s image and convert it to the format supported by the managed cloud.

Learning how OpenNebula is being used in real case scenarios is very motivating. This is why the team is very excited with the OnLife Project by Telefonica, which aims to build a CORD implementation using OpenNebula to virtualize and advance the Central Offices which gives you guys internet connection. Cool, isn’t it?

Also cool to learn how people spread the world, like this very interesting talk on OpenNebula and Ceph given in the Harvard IT Summit by the FAS Research Computing group.

If you are an OpenNebula newbie and english does not flow strongly on you, but you know french, check out this tutorial on how to install OpenNebula over a Debian OS.

It is always pleasant to receive praise such as this one, specially after releasing a Beta version, and also specially being a Beta as feature packed as Medusa 5.4 Beta. We are counting on you to unearth as many nasty bugs as possible before the final release! Please let us know through the community forum or the development portal about such findings. The call for translations of the Sunstone web interface to different languages is still open, check out the instructions on how to contribute to the translations. THANKS!

Telefonica using OpenNebula in the OnLife Innovation Project about Edge Computing

Centralized clouds are not appropriate for applications that require moving large amounts of distributed data or with interactive users that require low latency and real time processing, like Internet of Things (IoT), video streaming, gaming and many mobile applications. These applications require pushing data and processing away from centralized data centers to the extreme of the network closer to users where possible, this is called edge or fog computing.

Telecommunications companies are in a unique position to solve this problem because central offices (COs) are usually located close to their customers’ premises and thus close to IoT devices. In addition, COs can be transformed into clouds. Similar to the cloudlet concept, in which small-scale cloud datacenters at the edge of the Internet are used to support resource-intensive and interactive mobile applications, this can extend IoT service providers’ computing facilities to the network edge.

There are several initiatives to achieve this goal, mainly built around mobile-edge computing (MEC)—a network architecture concept that enables cloud-computing capabilities and an IT service environment at the edge of the cellular network. Among these, the Central Office Re-architected as a Datacenter (CORD) initiative seems to be better suited for convergent telecoms, as it integrates network function virtualization (NFV) and software-defined networking (SDN).

Telefónica is utilizing open-source OpenNebula and ON.Lab’s ONOS to prototype a new generation of CORD-based Central Offices that are fully IPv6 compliant and allow for the deployment of programmable services rather than the traditional black box solutions provided by proprietary solutions. Telefónica’s OnLife project aims to virtualize the access network and give third-party Internet of Things application developers and content providers cloud-computing capabilities at the network edge.

Maintaining an OpenNebula addon is not an easy task, but it is a crucial one for the success and widespread adoption of a third party component. Keeping up to date, and tested, against the latest OpenNebula version is of paramount importance to ensure its use by OpenNebula users. We want to bring you attention over the expertly crafted LXDoNe, and addon to enable OpenNebula on the management of LXD Containers. LXD is a daemon which provides a REST API to drive LXC containers. Containers are lightweight OS-level Virtualization instances, they behave like Virtual Machines but don’t suffer from hardware emulation processing penalties by sharing the kernel with the host.

Our friends at Comsysto have published a very interesting article on how to build a Private Cloud infrastructure with OpenNebula. This efforts are very important for the community since they spread the word and help to present what OpenNebula is about under other perspectives, enriching the ecosystem.

With OpenNebula we can build a simple and robust infrastructure that is focused on users needs and not on vendor specifics. Upon basic setup, user’s can already benefit from the installation because OpenNebula enables the user to be self-sustained and not to depend on System administrator or vendor to create and manage their VM’s. It is easily scalable and it can be installed on top of most hardware.

It is also very satisfying to learn how fellow developers chose OpenNebula to build their Continuous Integration infrastructures, like this fine article by the Qt folks.

Two thumbs up to all the OpenNebula advocates that support new OpenNebula users (or more seasoned users) in our support forum and in the IRC channel at freenode (#opennebula). You are a great asset to this project!

We do our best to review and incorporate those PRs aligned with the OpenNebula roadmap. We are grateful for the numerous contributions that help stabilize and enhance the OpenNebula software.

OpenNebula new major release is almost in feature freeze, and the numerous new additions are being stabilized. The vCenter driver is getting a major revamp in terms of storage and network management (check out more details in this article), non persistent disks and storage quotas, as well as network creation, mean an important boost in vCenter support. These new features will enhance OpenNebula provisioning model over vCenter based infrastructures, increasing the already wide range of use cases that can be implemented.

OpenNebula HA configuration in the front-end has been possible for quite a while. It currently relies on external components to ensure this HA, but the team decided that we may as well go all the way and implement HA natively in the OpenNebula front-end, implementing a consensus algorithm directly in the ‘oned’ core. The key improvement is the easier setup of the HA and the reduction of third party dependencies (no fencing, no corosync needed) and even more importantly, much less painful (in fact, completely ) failure recovery. Extensive testing is now performed on this functionality so you can add yet another 9 in your OpenNebula cloud availability!

More exciting features in 5.4 are: VM to VM and VM to Host affinity/antiaffinity using VM Groups, image persistency selection, modifiable semantics for permissions, IPv6 non SLAAC Address Ranges, Linked Clones support, improvements in monitoring drivers and much more!

Check out in the project’s development portal all the things we are still working on.

Building a ecosystems is instrumental in the success of a open source project. Thanks to people interested in OpenNebula, the amount of use cases that can be built with OpenNebula keeps growing and growing.

For instance, Devuan support is now a reality in OpenNebula, with support packages that ensures a proper contextualization of this novel and refreshing linux distribution.

It is always with pleasure hearing how people learn about OpenNebula, and realize that we’d been making cloud computing easier for you for quite a while now. Also, and as always, we love to see our friends at NodeWeavers being so supportive all over this last years. Kudos!

We would like to thank everyone that is actively supporting new OpenNebula users (or more seasoned users) in our support forum. Your actions are extremely useful for the adoption of OpenNebula around the globe!

An indicator of the health of the development community is the number of open pull requests in the OpenNebula GitHub page. We do our best to review and incorporate those aligned with the OpenNebula roadmap. Thanks!

OpenNebula 5.4 is going to place a new mark in cloud management excellence. A wealth of new features are being now stabilized, and that is what’s keeping the development team busy these days. As you know, the vCenter driver is getting a major revamp in terms of storage and network management (check out more details in this article). These new features will enhance OpenNebula provisioning model over vCenter based infrastructures, increasing the already wide range of use cases that can be implemented with your favourite Cloud Management Platform.

Let us lay down another set of features that are recent arrivals to the release:

  • Enhanced VM history logging
  • Image persistency selection
  • Modifiable semantics for permissions
  • IPv6 non SLAAC Address Ranges

.. and there will be more before the beta is released by the end of the month!

The team is particularly excited about the scheduler new ability of creating VM Groups with roles in which you can define affinity/anti affinity between VMs and virtualization hosts. This way OpenNebula supports use cases where VMs needs to be placed together for license issues, network performance reasons (place the DB and server together for instance), computational reasons or a wide range of other use cases. As usual, a picture speaks a thousand words. This feature has been sponsored by BlackBerry in the context of the Fund a Feature program.

New advancements in the community are always a pleasure to review, it is the time to notice that the OpenNebula community is as supporting and caring as always. Newcomers surely feel the warmth of the support forum, where users, developers and integrators give their best to aid users with questions and problems about OpenNebula and really interesting use cases. We’d like to show this spirit with this thread, where people show their best to help use OpenNebula with resources from a hosting company. Way to go!

It is always a pleasure learning how OpenNebula is used in a wide range of industry niches and institutions, like it use in the Turin INFN science cloud. Building reliable and useful, real world clouds is our main goal all along!.

An excellent post describing the hybrid model and why is interesting for enterprises and institutions is featured in the OpenNebula blog this month. The hybrid model in OpenNebula is a native capability, which can leverage the traditional cloud promise: infrastructure elasticity.

The idea of combining resources of public cloud providers with private depending on the terms of execution, the need of more resources, an extra protection of the data, more or less security in services with sensitive information, etc. are some of the capabilities that this model has to answer.

NodeWeavers shows us how to create an OpenNebula cloud in record time. Whoa! Their portable cloud looks nifty indeed!

We are very proud to announce that OpenNebula is a key components of the recently announced Telefonica rendering of the CORD framework (R-Cord)! We believe this is an important step to develop resilient clouds to deliver residentials phone and cloud services to end users. The architecture of the solution can be found here and it is a good read for all people interested in cloud and NFVs.

Outreach

The OpenNebulaConf is the perfect spot to meet up with other cloud professionals and take the temperature of the cloud computing field (check the material of 2016 edition if you want to know more). The first US edition of the OpenNebulaConf is happening this 2017, as one of 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.

June is approaching fast! Have your seat prepared in Boston? If you are interested listening at what Harvard and Akamai have to say about their use of OpenNebula in their production infrastructures, then you need to move quickly and make sure that you get a place!

This past month members of the OpenNebula team went to Prague, and did the first test on the field of the new tutorial format where the cloud is deployed within a public cloud provider. This helped a lot for people with Windows or 32 bit laptops.

TechDay Prague 2017 Wrap Up

This little post is here only to thank the people from CESNET for organizing the event. I also want to thank the attendees for sharing the day with me.

We’ve changed the format of the TechDay a bit and it turned out to be great:

  • The tutorial now is done in prepared laboratories in the cloud. This helped a lot for people with Windows or 32 bit laptops.
  • Instead of talks after the lunch there was a demonstration of OpenNebula and vCenter and a session of QA where the attendees could ask for specific features or how to accomplish some workflows.
