OpenNebula 5.4 ‘Medusa’ Beta is Out!

The OpenNebula project is proud to announce the availability of the first beta release of OpenNebula 5.4 ‘Medusa’. This version is the third release of the OpenNebula 5 series. A significant effort has been applied in this release to stabilize 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!

vcenter_network_create

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. 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.

vmgroups_ilustration

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.

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. Note that being a beta there is no migration path from the previous stable version (5.2.1) nor migration path to the final stable version (5.4.0).

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.

Community

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.

Technology

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.

pasted-image-at-2017_04_28-03_00-pm

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.

Community

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.

Community

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.

Technology

OpenNebula 5.4 is approaching fast its first beta release. The vCenter driver is undergoing a major refactoring, and the storage and networking aspects, as well as import mechanism are getting a whole pack of new functionality. Other important functionality that will make it into 5.4 is: linked clones, vSphere 6.5 support, public and private marketplaces, new cache mechanism that means performance enhancements, and much more!

But not only vCenter is getting its share. More general functionality is also in the works, with exciting new possibilities like defining VM Groups to implement affinity and anti affinity rules for VM deployment. This enables multiple use cases in which the colocation (or not) of VMs between them or with particular hosts is relevant. This added to the improvement in permissions definition -giving more flexibility to who can execute what-, enhanced history logging, image persistency selection, general Sunstone improvements and many more means that 5.4 is going to be special release indeed, which we believe will bring much joy to cloud admins and users alike.

Saying that the OpenNebula community excels is an understatement. The ecosystem keeps getting richer thanks to amazing contributions such as this one. LXDoNe is an active project based on an add-on that allows OpenNebula to manage LXD containers. It contains a virtualization and monitoring drivers, and it feature life cycle control: deploy, shutdown, restart, reset, suspend and resume containers.

It is a fact that the OpenNebula technology has a broad adoption, not only in US and Europe, but all around the globe. This is an important step towards standardising OpenNebula as the de facto Cloud Management Platform for IaaS infrastructures that strive for simplicity and innovative features. This is why it is of the utmost importance the huge work made by people all around the world to spread the OpenNebula word to different countries.
