OpenStack uses virtio driver as default model for both networking and disk devices. Virtio takes advantage of paravirtualization and enables guests to get high performance network and disk operations. However, OpenStack also supports some alternate options to enable custom models for KVM/Qemu hypervisor.
In order to use custom models, KVM users can change the image_meta properties and select the desired driver.
IBM PowerKVM provides support to ibmveth and ibmvscsi drivers as an alternative to the default... [More]
We would call your attention to a recent article " Why Linux on Power? " in the developerWorks Linux Zone which discusses the many good reasons to consider Linux.
As summarized from the article written by Grace Liu, Ann McDermott, and Mark Rudisill:
Running your Linux-based applications on IBM® Power® hardware offers a powerful blend of performance, reliability, and security. In this article, you will be exposed to many of the strategic advantages that IBM Power Systems™ can... [More]
IBM PowerKVM runs the OpenStack integration tests using a "CirrOS-like" image, a minimal Linux distribution that was designed for use as a test image on clouds.
This article shows how to build a custom cloud image for Power and how to use it on OpenStack Tempest suite.
The tiny image has less than 10MB and boots a custom mainline Kernel with built-in virtio drivers in less than 9 seconds. The rootfs is built with buildroot release 2014.05 and the resulting image is bundled with the scripts provided in CirrOS-0.3.2.
Ever wonder what's going on behind the scenes?
We follow a number community efforts going on in the industry. Recently, Breno posted an update to the debian realm of enabling ppc64el. Following the links, over 7000 packages have been built and are ready. Less then 600 packages are being worked, and various package dependencies are tracked.
This work, to varying degrees, continues across kernel.org, openstack, fedora, opensuse, and many others. We encourage readers and users to find the... [More]
We've had recent reports that SLES 11 SP3 won't install on a POWER8 system.
The install fails 5 seconds into the process with "Can't allocate memory for kernel image !" and stopping at the open firmware prompt.
We're hunting down the root cause information (being in development makes me very curious about these things). But in the meantime, our esteemed colleague Nigel Griffiths nicely hunted down the work-around which is available on SUSE's web site

This technical preview tutorial explains how users of IBM's latest POWER8-based scale-out Linux servers can try Ubuntu running non-virtualized. We show how Ubuntu can be installed directly on the OPAL firmware, and run as a single-image operating system directly on the system.
Ubuntu 14.04 is generally available today and fully supported as a PowerKVM guest on the IBM Power Systems shown below:
Three new authors have developed and published a new tutorial on the system bring-up of IBM PowerKVM on POWER8 over on the IBM developerWorks Linux Zone.
The IBM developerWorks Linux Zone - http://www.ibm.com/developerworks/linux/ - provides a great variety of Linux focused tutorials, article, and other technical resources for Linux programmers and system administrators. In addition, the "Zone" is looking for new articles, consider submitting yours today at https://www.ibm.com/developerworks/ideas .... [More]

As part of the June 10, 2014 POWER8 GA, several new documentation resources have been published. Use these documents to understand the ins-and-outs of running PowerKVM on your Linux on Power system.
IBM PowerKVM concepts
Learn the basics about PowerKVM, including how the important terminology differs from traditional Power virtualization (PowerVM). This topic also discusses the suggested system limits.
The IBM Software Development Kit for PowerLinux (SDK) is a free, Eclipse-based Integrated Development Environment (IDE). The SDK integrates C/C++ source development with the Advance Toolchain, Post-Link Optimization, and classic Linux performance analysis tools, including Oprofile, Perf and Valgrind.
New in the version 1.5:
Updated Java Version:
IBM SDK Java™ Technology Edition, version 7.1 .

As promised, here is my first blog post on little endian or "LE" as we call it. Where better place to start than with a list of frequently ask questions (FAQs)? Hopefully, you'll find this helpful. Let me know if you have any questions I missed.
What is big endian and little endian, anyway?
In order to perform operations on data, computers routinely load and store bytes of data from and to memory, the network, and disk. This data... [More]
OpenPOWER and the Power Linux distributions are based on POWER, the industry's leading RISC architecture for UNIX and Linux servers.
POWER8 is the first implementation of Power ISA v2.07 with many innovations supporting efficient exploitation of many-core and many-thread functions and optimized for Cloud Computing, Big Data and Business Analytics workloads from the ground up.
Power ISA 2.07 and POWER8 also contain increased support to ease transition from other platforms to the Power ecosystem to allow even more... [More]
I would like to announce a draft of a PowerKVM Redbook.
PowerKVM is an open source hypervisor based on the POWER8™ technology. On the following document, you will learn how to set up and configure this hypervisor. It will also cover how to control KVM from the console and WebUI interface.
IBM Redbooks are great technical collateral intended to quickly bring you up to speed with the latest technologies, offerings, and best... [More]
