New Contextualization Packages

A new version of OpenNebula context packages is out. Don’t be fooled by its version number. Even if it’s 4.14 is compatible with previous versions. There’s only one feature that needs OpenNebula 4.14 support.

In this release we a couple of contributions:

The other nice feature that you can use is that you can add start scripts without registering a file. To use this feature there are two new variables:

  • START_SCRIPT: the commands to run when the VM starts
    START_SCRIPT_BASE64: the same as START_SCRIPT but in base64
  • When context finds one of these variables it creates a new file that contains its value. Sets the executable bit, changes the directory to the context CD mount point and starts it. As it is executed by the context scripts all the variables in the context section are set in the environment.

The script does not need to be shell script, you can add a shebang and execute python, ruby or even binaries! (not recommended).

Some examples:

START_SCRIPT="yum update; yum install epel-release"
START_SCRIPT="
yum install nginx
systemctl start nginx
systemctl enable nginx
curl --data IP=$NIC[IP, NETWORK=\"public net\"] http://myserver/i_am_alive
"
START_SCRIPT="#!/usr/bin/env ruby

require 'open-uri'

open('http://myserver/configuration') do |s|
  conf = s.read
end
"

The other feature that requires the next version of OpenNebula is a new command to make the usage of OpenNebula gate easier. But we will talk about this in other post.

Go and download the new version while it’s fresh!

vOneCloud 1.6 Released! Ease vSphere Provisioning

We want you to know that OpenNebula Systems has just announced the availability of vOneCloud version 1.6.

This new release of the appliance, tailored to ease the provisioning of resources from vSphere based infrastructures, comes packed with exciting new features.

  • In vOneCloud 1.6 is now possible to define virtual machine capacity, in terms of CPU and Memory presented to the guest OS, changing this value from the vCenter Template at the time of cloning a new Virtual Machine.
  • Along this line, it is also possible to resize the capacity of a Virtual Machine after deployment.
  • Moreover, it is also possible to confine vOneCloud users on a particular vCenter Resource Pool, making it possible to enforce company security policies by reducing the rights of the needed credentials by the appliance and also offering to vOneCloud users a subset of all the available hardware resources controlled by vCenter.
  • In order to facilitate the customization of Virtual Machines, in terms of configuring software packages and perform any generic administration task at guest OS boot time, vOneCloud introduces the ability to run any script at boot time, using a new set of contextualization packages.
  • Improvements are also offered in the VNC connection capabilities, to accommodate foreign keyboards.

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, self-service portal, or hybrid cloud computing to connect in-house vCenter infrastructures with public clouds. 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.

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 happen (as strange at that may be!) to don’t like it  you can just remove the appliance.

OpenNebula Newsletter – May 2015

Check out what kept us busy this May. This Newsletter contains the most worthy developments and events of the OpenNebula project and the community during this last month, and the plans for the upcoming months.

We are proud to announce that OpenNebula Systems, the company behind the OpenNebula Project and vOneCloud, has established a new subsidiary to oversee all business operations and to support the OpenNebula community in the U.S. This is excellent news for the OpenNebula Project! Read the details in the OpenNebula Systems press release.

Technology

Winter is over, Spring is here, and everything is blossoming. And yes, that includes OpenNebula features! The team is busily working on the upcoming 4.14 OpenNebula release, as usual following the roadmap driven by its users, via feature request or even the Fund a Feature program.
OpenNebula 4.14 will add an exciting new snapshot management feature, that will let perform disk snapshots and maintain a history of them. The initial support would be only for Ceph, as it is our storage backend of choice (have you read our reference architecture? now is the chance!)

Sunstone is undergoing a major refactor, since its structure has been left untouched for far too many releases. We are proud to say that now all the components of OpenNebula have clean code and best programming practices! Of course everything has room for improvement, and we did our best in this release for your favourite cloud web interface. Adding new features and polishing the interface is going to be easier than ever now, so expect a big boost in Sunstone for future releases.

A long awaited featured, widely demanded by users, was related to datastore maintenance. Migrating running VMs from one system datastore to another, in order to take offline one datastore or simply to free some space from it will be possible in the upcoming 4.14 release. Rejoice cloud admins!

Image resizing has also been in our backlog for too long, and finally we found the needed resources to develop it. We think this is a very important feature for OpenNebula users and admins, try it out and let us know if this is what you were looking for.

4.14 will have a plethora of new features and improvements, like an improved fault management with the inclusion of new VM state transitions (no VM left behind), improvements in the network context management (more flexibility at the time and place of defining network attributes, … . Make sure you try out the beta release, due in a few weeks.

Community

We love our community. Seriously. Keep it up guys. Want a taste? Check this excellent contribution, detailing the needed steps to create an OpenNebula marketplace image. And when we say detailing, we really mean it. Great post! Also, a great contribution itself to the marketplace! A VyOS image for OpenNebula to achieve complex network topologies for your VM services.

We are very excited about uCloud, Unity Technologies new OpenNebula cloud. uCloud is a state of the art cloud, with authentication and network federation linking three different datacenters based on SoftLayer bare metal, configured for cloud bursting and prepared to scale to support thousands and even millions of users as Unity Technology requires. Read more details on this post we prepared to show the world what can be achieved in little time with OpenNebula, and also in the post the gentle folks at unity have prepared, called Agnostic Cloud Management (we like!).

Fun is always welcome in our community. The team choked in laughter after seeing this tweet from Carlo Daffara (kudos to your friends).

The Barcelona OpenNebula user group is very active, spreading the ONE word this month in the Suoders event, with interesting talks around the technology.

Serious matters are welcome as well. Our Terradue partners gave this talk at the EFIConf15 on Hybrid Cloud Strategy. Worth going through the slides.

What is the best way to move out of Amazon Web Services (AWS) or other public cloud services?

Well, according to iSpot.tv the answer is OpenNebula. Learn the reasons and the approach taken by them in this article.

The community is always contributing back. This month, it provided for instance gems to make OpenNebula a provider for Vagrant, and daemon for getting monitoring data from OpenNebula’s XML-RPC API and storing them to InfluxDB. Also, a very interesting Elastic load-balancing & high-availablitY Wired network Architecture. It comes packed with features, so if you are looking for complex network set ups is a must read. Moreover, a new version of knife plugin for OpenNebula is also available thanks to Megam.

A beta release of CLUES (energy management system for Cloud infrastructures) that supports OpenNebula was also released this month.
