Get an overview of the work and achievements during the last month, along with community updates, contributions and new integrations.

We are getting used to having great news every month, and June has brought us many many joys. Keep reading to discover why we had such a great period.

As a quick reminder, we would like to state that Santa Clara’s TechDay is the next big event in our agenda. Do not miss the chance to come!

Technology

OpenNebula 5.6 is here!!

Well, almost. We have released OpenNebula ‘Blue Flash’ Release Candidate which is just one step from being completely ready. You know we like to do things right even if it takes a bit longer. You can help us downloading this RC version, testing and reporting issues through our GitHub project or our community forum.

The OpenNebula team is now set to bug-fixing mode. Note that this is a Release Candidate aimed at testers and developers to try the new features, and send a more than welcomed feedback for the final release.

Of course we didn’t forget about our stable release OpenNebula 5.4 for which we have uploaded a maintenance release 5.4.13 including all the bug fixes from previous hotfix packages. You can download this built packages here.

Moreover we got some bugs solved in our latests hotfix updates OpenNebula 5.4.14 and 5.4.15

You know we, at OpenNebula, love to make your life easier, that is why we are so excited to present you the new oneprivision tool. Yes, as you might have guessed, this will make your host provisioning much quicker and easier. By just running a few commands you will be able to have a complete bare-metal host configured and running perfectly integrated with your cloud front-end. Our engineering team has tested this tool with Packet bare-metal servers and it works as a charm!

You can read everything about this new provisioning tool thanks to Alejandro Huertas, who has written this article containing a description and a how-to-use guide.

Community

It is impressive to be almost in July with the summer started and see how some of you are still working on bringing some great features to OpenNebula, instead of having a relaxing bath on the freshwater by the sea. We truly appreciate ;)

Before listing all the contributions of the community I would like to remind you that, until the day we release the stable version of OpenNebula 5.6, you still have time to help with the translations. So if you want OpenNebula to speak your language, contribute through this link. Contributions of any size are welcomed so don’t be shy.

To start with, we want to let you know that you now dispose of the latest Devuan ASCII free guest images ready to import in your OpenNebula infrastructures. You can check this neat tutorial for details on where to download and an installation guide.

Having new technologies integrated with OpenNebula is one of the biggest pleasures for the OpenNebula Team, this is why we are very excited to present the new TM driver developed by our colleagues at LizardFS. With this driver OpenNebula and LizardFS storage ar fully blended. For further information visit the following link.

Next, we would like to thanks @bestopensource for their great job on promoting open source projects like OpenNebula. This week they reminded all OpenNebula administrators that they can use this collection of scripts created by one of our most experienced and active users. Find these scripts here.

Also in Twitter Lorenzo Faleschini, CTO at NodeWeaver points out the easiness of working with OpenNebula:

 

Playing around with @nodeweaver at @HigecoSrl.
Devs are enjoying the ability to boot entire infrastructures to test their stack with a couple of clicks.
@opennebula Flow Happiness is in the air.

 

Outreach

Still a long way to the OpenNebulaConf 2018, however, we keep working on the organization to get interesting talks regarding open source projects and OpenNebula use cases in real world scenarios. Remember that if you register before the 15th of September you will have a 20% discount!

We know some of you can’t wait until November to see us but do not worry, we will be present in many events this summer.

If you live in the US this is your lucky summer. First you will be able to visit us at the VMworld US in Las Vegas on the 26-30th of August and then we will be present at Santa Clara’s OpenNebula TechDay hosted by Hitachi in their headquarters on the 30th of August. This TechDay is costless so feel free to register here and join us. Visit the event’s website to get all the information related.

Of course, as every year, we will have a booth at VMworld EU 2018 that will be held on the 5-8th of November in Barcelona presenting some of the greatest advances coming in OpenNebula Blue Flash.

We have some other events coming in between like Frankfurt TechDay hosted by LINBIT. Check out our official agenda to see more events and updates.

Okay, enough talk-shop!

I want to grasp this newsletter to wish you all, happy and long holidays. See you next month, with a nicer tan I hope ;)

OpenNebula 5.6 (Blue Flash) is the fourth major release of the OpenNebula 5 series. A significant effort has been applied in this release to enhance features introduced in 5.4 Medusa, while keeping an eye in implementing those features more demanded by the community. A massive set of improvements happened at the core level to increase robustness and scalability, and a major refactor happened in the vCenter integration, particularly in the import process, which has been streamlined. Virtually 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.

Following our tradition this OpenNebula release is named after NGC 6905, also known as the Blue Flash Nebula, a planetary nebula in the constellation Delphinus. It was discovered by William Herschel in 1784.

The OpenNebula team is now set to bug-fixing mode. Note that this is a RC 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 RC there is no migration path from the previous stable version (5.4.13) nor migration path to the final stable version (5.6.0).

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 SetUID/SetGID functionality for VM Templates is funded by University of Louvain. The Ceph drivers enabling VM disks in the hypervisor local storage are funded by Flexyz B.V.

During the last months we have been working on a new internal project to enable disaggregated private clouds. Our aim is to provide the tools and methods needed to grow your private cloud infrastructure with physical resources, initially individual hosts but eventually complete clusters, running on a  remote bare-metal cloud providers.

Two of the use cases that will be supported by this new disaggregated cloud approach will be:

  • Distributed Cloud Computing. This approach will allow the transition from centralized clouds to distributed edge-like cloud environments. You will be able to grow your private cloud with resources at edge data center locations to meet latency and bandwidth needs of your workload.
  • Hybrid Cloud Computing. This approach works as an alternative to the existing hybrid cloud drivers. So there is a peak of demand and need for extra computing power you will be able to dynamically grow your underlying physical infrastructure. Compared with the use of hybrid drivers, this approach can be more efficient because it involves a single management layer. Also it is a simpler approach because you can continue using the existing OpenNebula images and templates. Moreover you always keep complete control over the infrastructure and avoid vendor lock-in.

 

There are several benefits of this approach over the traditional, more decoupled hybrid solution that involves using the provider cloud API. However, one of them stands tall among the rest and it is the ability to move offline workload between your local and rented resources. A tool to automatically move images and VM Templates from local clusters to remote provisioned ones will be included in the disaggregated private cloud support.

In this post, we show a preview of a prototype version of “oneprovision”, a tool to deploy and add to your private cloud instances new remote hosts from a bare-metal cloud provider. In particular, we are working with Packet to build this first prototype.

Automatic Provision of Remote Resources

A simple tool oneprovision will be provided to deal with all aspects of the physical host lifecycle. The tool should be installed on the OpenNebula frontend, as it shares parts with the frontend components. It’s a standalone tool intended to be run locally on the frontend, it’s not a service (for now). The use is similar to what you may know from the other OpenNebula CLI tools.

Let’s look at a demo how to deploy an independent KVM host on Packet, the bare metal provider.

Listing

Listing the provisions is a very same as listing of any other OpenNebula hosts.

$ onehost list
ID NAME        CLUSTER RVM   ALLOCATED_CPU   ALLOCATED_MEM STAT
 0 localhost   default   0    0 / 400 (0%)  0K / 7.5G (0%) on

$ oneprovision list
ID NAME            CLUSTER RVM PROVIDER STAT

Based on the listings above, we don’t have any provisions and our resources are limited just on the localhost.

Provision

Adding a new host is as simple as running a command. Unfortunately, the number of parameters required to specify the provision would be too much for the command line. That’s why most of the details are provided in a separate provision description file, a YAML formatted document.

Example (packet_kvm.yaml):

---

# Provision and configuration defaults
provision:
    driver: "packet"
    packet_token: "********************************"
    packet_project: "************************************"
    facility: "ams1"
    plan: "baremetal_0"
    billing_cycle: "hourly"

configuration:
    opennebula_node_kvm_param_nested: true

##########

# List of devices to deploy with
# provision and configuration overrides:
devices:
    - provision:
          hostname: "kvm-host001.priv.ams1"
          os: "centos_7"

Now we use this description file with the oneprovision tool to allocate new host on the Packet, seamlessly configure the new host to work as the KVM hypervisor, and finally add into the OpenNebula.

$ oneprovision create -v kvm -i kvm packet_kvm.yaml
ID: 63

Now, the listings show our new provision.

$ oneprovision list
ID NAME            CLUSTER RVM PROVIDER STAT
63 147.75.33.121   default   0 packet   on

$ onehost list
ID NAME            CLUSTER RVM ALLOCATED_CPU      ALLOCATED_MEM STAT
 0 localhost       default   0  0 / 400 (0%)     0K / 7.5G (0%) on
63 147.75.33.121   default   0  0 / 400 (0%)     0K / 7.8G (0%) on

You can also check your Packet dashboard to see the new host.

Host Management

The tool provides a few physical host management commands. Although you can still use your favorite UI, or provider specific CLI tools to meet the same goal, the oneprovision also deal with the management of the host objects in the OpenNebula.

E.g., if you power off the physical machine via oneprovision, the related OpenNebula host is also switched into the offline state, so that the OpenNebula doesn’t waste time with monitoring the unreachable host.

You will be able to reset the host.

$ oneprovision reset 63

Or, completely power off and resume any time later.

$ oneprovision poweroff 63

$ oneprovision list
ID NAME            CLUSTER RVM PROVIDER STAT
63 147.75.33.121   default 0   packet   off

$ oneprovision resume 63

$ oneprovision list
ID NAME            CLUSTER RVM PROVIDER STAT
63 147.75.33.121   default 0   packet   on 

Terminate

When the provision isn’t needed anymore, it can be deleted. The physical host is both released on the side of the bare metal provider and the OpenNebula.

$ oneprovision delete 63

$ oneprovision list
ID NAME            CLUSTER RVM PROVIDER STAT

$ onehost list
ID NAME            CLUSTER   RVM  ALLOCATED_CPU    ALLOCATED_MEM   STAT
 0 localhost       default     0   0 / 400 (0%)   0K / 7.5G (0%)   on

Stay tuned for the release of this first feature of our new cloud disaggregation project, and as always we will be looking forward to your feedback!

We are glad to announce that our friends from LINBIT will organize the first OpenNebula TechDay in Frankfurt.

As usual in this TechDay you will be able to enjoy a full experience around cloud and open source projects. There will be talks and presentations from experienced people working with LINBIT and OpenNebula.

Yes! A 4 hour long Hands-on tutorial will be conducted by OpenNebula experts so that the attendees are able to see in action and manage their own private  cloud!

Virtually 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.

In this release several development efforts have been invested in making OpenNebula even better for large scale deployments. This improvements includes both, changes in OpenNebula core to better handle concurrency as well as refined interfaces. Sunstone dashboard has been redesigned to provided sensible information in a more responsive way. Sunstone also features some new styling touches here and there, and it has been updated to version 5 of Fontawesome.

Blue Flash also includes several quality of life improvements for end-users. In particular, it is now possible to schedule periodic actions on VMs. Want to shutdown your VM every Friday at 5p.m. and start it on Monday 7p.m. just before work… We got you covered. Also, don’t to want accidentally terminate that important VM or want to freeze a Network; now you can set locks on common resources to prevent actions to be performed on them.

sched_actions

5.6. ends the major redesign on the vCenter driver started in 5.4. The new integration with vCenter features stability and performance improvements, as well as important new features like a extended multicluster support or a redesigned importation workflow with new Sunstone tabs as well as a new CLI.

Following our tradition this OpenNebula release is named after NGC 6905, also known as the Blue Flash Nebula, a planetary nebula in the constellation Delphinus. It was discovered by William Herschel in 1784.
