Next week in Los Angeles, I’ll be giving a talk at the SCALE 13x conference on oVirt’s new OptaPlanner-powered scheduling adviser. Martin Sivák wrote a great post about the feature a couple of months ago, but didn’t cover its installation process, which still has a few rough edges. Read on to learn how to install […]

Atomic hosts are meant to be as slim as possible, with a bare minimum of applications and services built-in, and everything else running in containers. However, what counts as your bare minimum is sure to differ from mine, particularly when we’re running our Atomic hosts in different environments. For instance, I’m frequently testing and using […]

RDO, the community-oriented OpenStack distribution for CentOS, Fedora, and their kin, is super-easy to get up and running, as a recently posted YouTube video illustrates: At the end of the process, you’ll have a single-node RDO installation on which you can create VM instances and conduct various experimentation. You can even associate your VMs with […]

Back in November, I wrote about how to try out Kubernetes, the open source system for managing containerized applications across multiple hosts, using Atomic Hosts. In that post, I walked through a deployment of the Kubernetes project’s multicontainer “Hello World” application. This time, I thought I’d explore running a more real-world application on Kubernetes, while […]

This week, Fedora 21 (a.k.a., the release that must not be named) hit FTPs mirrors everywhere, with a feature list led by a new organizational structure for the distribution. Fedora is now organized into three separate flavors: Workstation, Server, and Cloud. Fedora’s Cloud flavor is further divided into a “traditional” base image for deploying the […]

Atomic hosts include Kubernetes for orchestration and management of containerized application deployments, across a cluster of container hosts. If you’re interested in taking Kubernetes for a spin on an Atomic host, read on! via Testing Kubernetes with an Atomic Host — Project Atomic.

Two weeks ago in this space, I wrote about how to deploy the virtualization, storage, and management elements of the new oVirt 3.5 release on a single machine. Today, we’re going to add two more machines to the mix, which will enable us to bring down one machine at a time for maintenance while allowing […]

Over the past several weeks, teams within the CentOS and Fedora projects have been establishing the processes needed to produce “Atomic Host” variants of their respective distributions. If you haven’t already done so, you can check out the latest pre-release Fedora Atomic and CentOS Atomic images. Now, consuming an OS that partakes in the hotness […]

Last week, version 3.5 of oVirt, the open source virtualization management system, hit FTP mirrors sporting a slate of fixes and enhancements, including a new-look user interface, and support for using CentOS 7 machines as virtualization hosts. As with every new oVirt release, I’m here to suggest a path to getting up and running with […]

I’ve tried out a lot of different software applications in my time, so I’ve come to appreciate projects and products that make it easy to get up and running quickly and without the need for assembling a whole labful of equipment. In this vein, the various components that comprise oVirt, the open source virtualization management […]
