In the second installment of “what’s new” for networking features in Red Hat Enterprise Linux 7, I’d like to shift the focus and spend some time talking about improvements to network time synchronization and enhancements in the network stack designed to reduce latency. Note that the previous installment of this two part series was posted during the Red Hat Enterprise Linux 7 beta; now that Red Hat Enterprise Linux 7 is generally available I encourage customers to visit the Red Hat Customer Portal, download this latest release, and to let me know what you think.
Highly Accurate Time Synchronization
Precise time synchronization with microsecond or nanosecond accuracy is increasingly critical to the success of many high-speed, low-latency applications. Whether tracking time on trading transactions or market feeds, improving the time stamp accuracy on archived data, or administration-free time synchronization of servers within a rack (or around the world) for automation or regulatory purposes, precision time synchronization is a key enabler for delivering better performance.
New to Red Hat Enterprise Linux 7,

When Red Hat Enterprise Linux 5 was first introduced in 2007, it was done so with an expected seven year lifecycle. Five years later, in 2012, we saw the continued strong adoption of Red Hat Enterprise Linux 5 and decided to extend its seven year lifecycle to 10 years. Now, in 2014, the original retirement year for Red Hat Enterprise Linux 5, we still see an active, dedicated customer base that has come to value this long, predictable lifecycle in addition to the platform’s inherent security, stability, and reliability.
Today, we are pleased to announce beta availability of Red Hat Enterprise Linux 5.11. This release continues to provide system administrators with a secure, stable, and reliable platform for their organization’s enterprise applications.

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:

For anyone who may not have read my previous posts on OpenLMI or who may have never visited my blog (TechPonder) – OpenLMI is a new management framework for Linux.
The most common initial questions about OpenLMI are:

For those not attending Red Hat Summit 2014 or not tracking the latest news and updates (available on the official Red Hat Summit Blog), you may have missed two important and exciting announcements, namely:
- A Red Hat Enterprise Linux 7 Release Candidate (RC) will be made publicly available (starting next week). As a pre-release build of Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 7 RC offers a near-final look at the only operating system crafted for the open hybrid cloud, building upon the feedback collected during the beta program for Red Hat Enterprise Linux 7.
- Also, Red Hat plans to introduce Red Hat Enterprise Linux Atomic Host as a new addition to the Red Hat Enterprise Linux family. Red Hat Enterprise Linux Atomic Host couples the flexible, lightweight and modular capabilities of Linux Containers with the reliability and security of Red Hat Enterprise Linux in a reduced image size that will enable easy movement of Red Hat Enterprise Linux-certified applications across bare metal systems, virtual machines and private and public clouds.
For more information on either the Red Hat Enterprise Linux 7 RC or our plans for Red Hat Enterprise Linux Atomic Host – I encourage you to visit: press.redhat.com
The advent of any new technology tends to generate a lot of excitement. Over the course of my career, however, I have never experienced “a buzz” like what we are seeing around Linux containers and application packaging and isolation, containerized applications built in the Docker format. From my perspective, the ways in which containers may influence our ever evolving technological ecosystem are, quite possibly, limitless…okay, limitless may be strong, and while “game changing technology” may sound cliche, it’s not far from the truth in this case.

OpenLMI will be represented at the upcoming Red Hat Summit, which is being held in San Francisco from April 14-17.
Stephen Gallagher and I will be giving a talk on OpenLMI, the new Linux Management Infrastructure, on Tuesday, April 15, at 10:40am. This talk will provide an overview of OpenLMI, cover its functional capabilities, and demonstrate using the LMIShell CLI and Scripts to accomplish common management tasks.

In a recent post, we reviewed the 10 world record results set by Red Hat Enterprise Linux on the Intel Xeon processor E7 v2 family. Besides showcasing the extreme capabilities of Red Hat Enterprise Linux, these performance achievements tell another compelling story – Red Hat Enterprise Linux has become an exceedingly popular choice when it comes to tough workloads.
For example, consider the share of Red Hat Enterprise Linux versus other operating systems used to produce these records. Out of 20 world record benchmark results (22 total submissions, 3 results were tied) posted by eight different OEM partners at the Intel Xeon processor E7 v2 family announcement, Red Hat Enterprise Linux was used in 12. Seventy-five percent of the hardware vendors taking part in this process chose to publish their world record benchmarks on the new family of processors using Red Hat Enterprise Linux. The chart below shows the significance of this adoption.

In upstream development news, the kernel team here at Red Hat has been working on a dynamic kernel patching project called kpatch for several months. At long last, the project has reached a point where we feel it’s ready for a wider audience and are very excited to announce that we’ve released the kpatch code under GPLv2.
kpatch allows you to patch a Linux kernel without rebooting or restarting any processes. This enables sysadmins to apply critical security patches to the kernel immediately, without having to wait for long-running tasks to complete, users to log off, or scheduled reboot windows. It gives more control over uptime without sacrificing security or stability.

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.
