If you have ever wanted to learn about Red Hat’s involvement in the ARM server ecosystem, and are in the San Francisco Bay Area, this week may be a perfect opportunity. Red Hat will be exhibiting at ARM TechCon, ARM Holdings’ premier yearly show at the Santa Clara Convention center. Attendees will be presented with a variety of great technical sessions and training topics, along with expert keynotes, solutions-based Expo Theater sessions and an expo floor filled with new and emerging technologies for the datacenter. Note that the expo floor can be accessed with the free

In our third and final installment (see: part one & part two), let’s take a look at some high-level use cases for Linux containers as well as finally (finally) defending what I like to call “pet” containers. From a general perspective, we see three repeated high-level use cases for containerizing applications:
- The fully orchestrated, multi-container application as you would create in OpenShift via the Red Hat Container Development Kit;
- Loosely orchestrated containers that don’t use advanced features like application templates and Kubernetes; and
- Pet containers.

Having access to quality random numbers is essential for correct and secure operation of operating systems. Operating systems need random numbers from an entropy pool for a variety of tasks, like creating secure SSH or GPG/PGP keypairs, generating random PIDs for processes, generating TCP sequence numbers, and generating UUIDs.
With Red Hat Enterprise Linux 7 we introduced the virtio RNG (Random Number Generator) device that provides KVM virtual machines access to entropy from the host machine. Red Hat Enterprise Virtualization starting version 3.5 also has exposed this feature. We have since made improvements to Red Hat Enterprise Linux guests to make the feature easier and more straightforward to use.
A Brief Introduction to virtio and Paravirtualized Devices
virtio is the paravirtualized transport framework for KVM virtual machines. Using the virtio framework, new devices can be

In November we announced Red Hat Enterprise Linux 7 Atomic Host Public Beta, a small footprint, container host based on Red Hat Enterprise Linux 7. It provides a stable host platform, optimized for running application containers, and brings a number of application software packaging and deployment benefits to customers.
What are the top 7 reasons to deploy containers on Red Hat Enterprise Linux 7 Atomic Host?

Six months ago we announced the beta availability of Red Hat Enterprise Linux 7. Two months ago, at Red Hat Summit 2014, we announced the availability of a release candidate for Red Hat Enterprise Linux 7. All the while we have been validating what’s new, different, and exciting about what Red Hat Enterprise Linux 7 has to offer – including:
Today we are pleased to announce the general availability of Red Hat Enterprise Linux 7, the latest major release of our flagship platform. As stated in this morning’s press release:

We’ve often talked about how Red Hat Enterprise Linux was fueling top benchmark results on the latest generation of Intel Xeon processors.
Today, we’re pleased to say that Red Hat Enterprise Linux has again demonstrated how an OS platform can handle the rigors of highly multi-threaded processing and on-demand scaling. In the most recent set of benchmarks done with one of the latest cutting edge processors, the Intel Xeon processor E7 v2 family, Red Hat Enterprise Linux claims 10 new world records. Here are these leading results at a glance:

Someone out there “gets” the title, right? No, I’m not suggesting that Red Hat Enterprise Linux 7 Beta is an interactive puzzle adventure game. The relationship, I suppose, is in fact based on a much looser association: this is our seventh major release and this post (as opposed to my first) is dedicated to Red Hat Enterprise Linux running as a guest on third party hypervisors.

Ever since Red Hat Enterprise Linux added KVM Virtualization as a kernel-based hypervisor to run virtual machines (way back in Red Hat Enterprise Linux 5.4), the operating system took on a dual personality.
Red Hat Enterprise Linux became both a Virtualization host for high density virtual data centers / cloud service platforms, and a guest operating system running on third party hypervisors such as VMware vSphere and Microsoft Hyper-V. As the topic is sufficiently broad, I plan to split my discussion of virtualization into two posts.
Today’s post will discuss Red Hat Enterprise Linux 7 beta as a hypervisor using KVM Virtualization technology and it will highlight a few key enhancements that make Red Hat Enterprise Linux the operating system of choice for modern hybrid data centers. While the features that I will review are inherently those that I find to be the most exciting (note: I’m hoping you will find them to be exciting and useful as well), a complete list is available in the Red Hat Enterprise Linux 7 beta release notes.
