We want to let you know that OpenNebula Systems has just announced the availability of vOneCloud version 2.0.

This new release of the appliance, based on a tailored version of OpenNebula 5.0 Wizard to ease the provisioning of resources from vSphere based infrastructures, comes packed with exciting new features. Coming from functionality present in 5.0 we found:

  • Datastore and VMDK image management, as well as import.
  • New Virtual Router Resource, to allow routing between isolated virtual networks.
  • More flexible vCenter VM naming, with a configurable prefix.
  • New resource pool mode, with the ability to select in which resource pool a particular VM is confined.
  • New OneFlow templates operations, like the ability to clone existing service templates.
  • Keep disks on done, to avoid deleting disks when the VM is terminated.
  • Instantiate to persistent, to easily create a rich VM Template catalog.
  • Dynamic VM reconfiguration, that can be performed while the VM is running or powered off.
  • Share resources between logical clusters, like Virtual Networks and Datastores.

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 2016 US in Las Vegas on August 28-31 and VMworld 2016 EU in Barcelona on October 17-20 where they will demo the new version.

The OpenNebula project is proud to announce the availability of the first stable release of OpenNebula 5.0 ‘Wizard’. This major update comes with several improvements in different subsystems and components, with minimal changes in the API and the VM life-cycle states, which embodies long overdue changes but implemented to minimize the impact and ensure backwards compatibility as far as possible.

A myriad of outstanding new features make their debut in Wizard. Sunstone never stops evolving, and this is the look and feel the team is most proud of to date.


Since sharing, provisioning and consuming cloud images is one of the main concerns when using Cloud, one of the most important new features is the new revamped Marketplaces. They can be seen as external datastores, where images can be easily imported, exported and shared by a federation of OpenNebula instances.

Check the following screencast to see an overview of the revamped interface present in OpenNebula 5.0 Wizard.

Native support for Virtual Routers is also great news in 5.0. Virtual Routers are an OpenNebula resource that provide routing across virtual networks. The routing itself is implemented with a VM appliance provided by the OpenNebula installation, which can be seamlessly deployed in high availability mode. This functionality is available for the VDC administrator, which can then join together virtual networks within her VDC.


For large scale deployments, a long overdue feature is the ability to group resources using labels, which is now present in Wizard’s Sunstone. This new feature will enable the possibility to group the different resources under a given label and filter them in the admin and cloud views.

For vCenter-based OpenNebula clouds, 5.0 is good news! Support for vCenter storage resources like Datastores and VMDKs enable a wealth of new functionality, like for instance VMDK upload, cloning and deleting, VM disk hotplug, choose Datastore for newly launched VMs and many more. Also, support for resource pools comes in this new major update, as well as the ability to instantiate to persistent (also available for KVM), all packed in an optimized driver.

There are many other improvements in 5.0, a few highlights follows. Check the full list of changes in the development portal.

  • Dynamic context regeneration
  • New host offline mode
  • Cluster resource sharing
  • VM configuration update
  • Renamed VM life-cycle
  • Support for DB change
  • Improved KVM, vCenter, and datastore monitoring
  • Better VNC port number assignment
  • Dynamic security groups
  • Updated instance types for the supported public clouds
  • Improved LVM drivers
  • Enabling use of Ceph without a shared filesystem for system datastore
  • A humongous number of improvements in all areas and dialogs in Sunstone
  • Enhanced OneGate component to report application metrics
  • As usual, great effort was put in this release to help build and maintain robust private, hybrid and public clouds with OpenNebula, fixing reported bugs and improving general usability

This OpenNebula release is named after NGC 7380 (also known as the Wizard Nebula), an open cluster also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter.

OpenNebula 5.0 Wizard 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.

Virtual Routers functionality was funded by Unity in the context of the Fund a Feature Program. Host offline mode, Marketplace, cluster resource sharing and Ceph as system datastore functionalities were funded by BlackBerry in the context of the Fund a Feature Program.

OpenNebula 5.0 Wizard is around the corner! With the Beta version released recently, the team is baking a release candidate, and is planning a final stable Wizard release for mid June. Wizard is in feature freeze, and the effort is focused on solving bugs. We appreciate your feedback if you have the time to try out the Beta version!
This are the highlighted gems that you can find in Wizard:

  • revamped Marketplace, now a first class citizen in OpenNebula, to import/export images to and from any datastore (including the new vCenter datastores)
  •  vCenter storage management, including datastore selection, disk hotplug, vmdk creation, cloning and deletion; and full integration with the new Marketplace functionality. Also, vCenter resource pool selection for deployed VMs will be possible.
  •  fully integrated virtual router management (including default and transparent HA for routers). Link virtual networks together using a robust HA router, that will come out of the box in OpenNebula
  •  revisited Sunstone style and interface changes (sneak peek), including an extension of the Cloud View available operations, to iron out the wrinkles in the user experience
  •  instantiate to persistent! Do not lose your VM changes, OpenNebula will create a new VM Template and preserver the disks of a VM, even if they are non-persistent.

Check the full list of feature in the development portal.
