Technology

With OpenNebula Medusa 5.4 published this past July, the team is focusing now on the next maintenance release, 5.4.1, as well as preparing the roadmap for the next major release, OpenNebula 5.6. This is the perfect time to contribute your ideas to improve OpenNebula, this page from the project’s website lays out all the needed info (TL;DR create a request in the development portal).

If you were wondering how to add patches to them or build non stable versions this is your lucky month, since the team just published the package build repository, so everyone can build their own OpenNebula packages.

This month of August was also good news for vOneCloud users, with the release of vOneCloud 3.0.0 (and subsequent 3.0.1), which brings all the innovation introduced in OpenNebula 5.4. You can check the details in the release notes, the following are highlights of the new functionality in vOneCloud 3.0.0:

  • Enhanced storage management, vOneCloud is fully aware of all VMs disks. Non-persistent images and volatiles disks are now supported.
  • Storage quotas and datastore capacity check, never run out of capacity correctly dimensioning the available datastores and the storage quotas given to end users
  • Linked clone support, add support for linked clones for VMs at the time of importing a VM Template
  • Disk resize capabilities, resize the capacity of a VM disk at boot time or when the VM is in poweroff
  • Network creation support, a new vCenter network model is available in virtual network definition, standard and different port groups and vSwitches can be created from within OpenNebula. VLAN IDs, MTUs and number of ports can be specified when a port group is created.
  • Full storage and networking support in imported VM Templates, images and networks representing disks and network interfaces are created for VM templates and folder placement features.

Community

The team put a lot of effort in Medusa, and we want to thank you for the marvellous feedback received in the community forum, as well as the support given by the community to newcomers and people willing to upgrade their OpenNebula infrastructures.

It is also very welcome how people are keeping up to date with the latest releases. We hope you enjoying using OpenNebula as much as we enjoy developing it!

Integrations such as this one from UDS Enterprise gives indeed more flexibility to OpenNebula, with the ability to manage a VDI environment in an OpenNebula based infrastructure.

Release 5.2-4.1 of the LXDoNe OpenNebula addon has been released. LXDoNe add LXD management capabilities to OpenNebula, bringing container management to the cloud!

Outreach

The OpenNebulaConf EU will take place in Madrid, Spain, this October. The conference will be packed with very interesting talks about the real world uses of OpenNebula, check the agenda for more details, keynotes feature BlackBerry, Trivago, Runtastic and the Ministry of the Flemish community. Also, make sure you register if you’ll be on the area! The conference is a great place to learn about OpenNebula and cloud computing in general, don’t take our word for granted and watch the talks in the YouTube playlist, download the slides or take a look to the pictures of the first US edition of the OpenNebulaConf that happened in Boston this past June.

The next OpenNebula TechDay will happen in Vancouver after the summer break, the 1st of September, hosted by Best Buy Canada. The event is almost full, so if you are in the area make sure you register a soon as possible, or risk missing the opportunity!

Also, check out the list of official training from OpenNebula Systems for this year. If you are new to OpenNebula, or want to improve you knowledge with an in-depth OpenNebula admin course, those are the dates and locations you need to keep in mind.

Remember that you can see slides and resources from past events in our Events page. We have also created a Slideshare account where you can see the slides from some of our recent presentations.

Alongside the release of OpenNebula 5.4 we have made the repository with package scripts and specs public.

It comes with documentation on how you can create your own packages in case you want to add patches to them or build non stable versions. This is the repository used to generate official packages so feel free to send pull requests in case you find problems.

 

OpenNebula Systems has just announced the availability of vOneCloud version 3.0. This is the first vOneCloud release that offers full storage and network management capabilities.

vOneCloud 3.0 is powered by OpenNebula 5.4.0 ‘Medusa’, and, as such, it includes functionality present in Medusa relevant to vOneCloud:

  • Enhanced storage management, vOneCloud is fully aware of all VMs disks. Non-persistent images and volatiles disks are now supported.
  • Storage quotas and datastore capacity check, never run out of capacity correctly dimensioning the available datastores and the storage quotas given to end users
  • Balance storage load of VMs across datastores automatically without the need of Storage DRS
  • Linked clone support, add support for linked clones for VMs at the time of importing a VM Template
  • Disk resize capabilitiesresize the capacity of a VM disk at boot time or when the VM is in poweroff
  • Save disk functionalityregister any VM disk as an image for later use in VMs, either directly from a VM Template or through the disk attach operation
  • Save as Template functionalitysave any VM as a VM Template at any point during its lifecycle
  • Folder management, define in which vCenter folder you want your VMs into, on a VM to VM basis.
  • Network creation support, a new vCenter network model is available in virtual network definition, standard and different port groups and vSwitches can be created from within OpenNebula. VLAN IDs, MTUs and number of ports can be specified when a port group is created.
  • Full storage and networking support in imported VM Templates, images and networks representing disks and network interfaces are created for VM templates and folder placement features.
  • Improved CDROM management, now a new CDROM drive is added to the VM if not present when an ISO image is attached
  • Imported VMs improvements, with the possibility of adding VNC to any imported VM.
  • Removed naming limitations, vCenter cluster and datastore names with spaces are now supported
  • Improved performance, up to two orders of magnitude of speedup in monitoring and import times, as well as less error prone synchronous calls to vCenter
  • Faster VM deployment, with up to 10 VM spinning up simultaneously per cluster
  • User input sorting, to ask information in the correct order to end users (for instance, username before password), and also new types (lists, booleans, etc)
  • Improved naming conventions, to allow importing resources with the same name in different vCenter locations
  • Numerous web interface enchancements, like automatic estimation of VM cost through the Showback mechanism, better VM information display in Cloud View, image upload resume option, improved user and group management dialogs and many more.
  • Better audit trail, now the history records of VMs includes the UID of the user that perfomed the action

Multiple bugfixes and documentation improvements have been included in this version. For instance, deleting SSH keys from cloud view, importing images with correct size, VM contextualization persistance across reboots, disk not removed if detached in poweroff state, context disk not displayed in Sunstone, skip import of resources if no permissions available, and a long list of other bugfixes and enhancements that can be consulted in the development portal.
