CES 2015: Smart Cars are the New Smart Phone

This is a reprint of the following Linux.com article by Alex Agizim, VP, CTO Embedded Systems at GlobalLogic

“Smart car” technology had a huge presence at CES 2015, from BMW’s 360-degree collision avoidance and parking assist features to Audi’s Human Machine Interface (HMI) that connects to an iPhone or Android device. And with both Apple and Google jumping into the market with their CarPlay and Android Auto IVI systems, the automotive industry is on the brink of some significant changes.

Future of Xen Project: Video Spotlight Interview with Intel’s Donald Dugger

Intel’s Virtualization Architect Donald Dugger started working on Xen Project software eight years ago. We recently interviewed Don to find out why Intel continues to support, contribute and invest in the Xen Project. One of the first companies to contribute to hardware-assisted virtualization, today Intel remains equally focused on actively promoting open source virtualization. The company continually adds new virtualization features in its CPUs and is constantly evolving its virtualization support.

Less is More in the New Xen Project 4.5 Release

If we used code-names, the Xen 4.5 release should be called Panda on Diet! We have 78K new code with 141K deleted. In effect this release has -63KLOC code than the previous one.

The net effect of a skinnier Xen Project Hypervisor code base is increased usability, simplicity and innovation. This is all by design and one of many steps we’ll continue to take to fine-tune our development and release cycle.

Set up GlassFish 4.1 Nova-Docker Container via docker’s phusion/baseimage on RDO Juno

The problem here is that phusion/baseimage per https://github.com/phusion/baseimage-docker should provide ssh access to container , however it doesn’t. Working with docker container there is easy workaround suggested by Mykola Gurov in http://stackoverflow.com/questions/27816298/cannot-get-ssh-access-to-glassfish-4-1-docker-container

Using Grub 2 as a bootloader for Xen PV guests

Background: Introduction to Xen PV Bootloaders

In the very early days of Xen it was necessary for the host (domain 0)
administrator to explicitly supply a kernel (and perhaps initial
ramdisk) from the domain 0 filesystem in order to start a new guest.

This mostly worked and for some use cases, i.e. those where the host
admin wants very strict control over what each guest runs, was
desirable and remains so today.

Running Nova-Docker on OpenStack Juno (CentOS 7)

Recently Filip Krikava made a fork on github and created a Juno branch using the latest commit +Fix the problem when an image is not located in the local docker image registry ( https://github.com/fikovnik/nova-docker/commit/016cc98e2f8950ae3bf5e27912be20c52fc9e40e )

Xen Project 4.5 Release Candidate 4 Test Day on December 17, 2014

Our Last Scheduled 4.5 Release Candidate Testing is on Wednesday

TestDay

The Test Day for 4.5 RC4 has been set for this Wednesday, December 17, 2014.

Test Days insure that the upcoming release is ready for production. It also allows all users to test out the upcoming release in their own environment.

Xen Project Contributor Training

A few weeks ago, I went onto a road trip to China with the aim to meet Xen Project users as well as contributors. When I was planning the trip, it became apparent that many of the developers in China are new to the project and had difficulties with Xen Project governance and how the project operated. As we also have had issues with increasing code review times due to a large influx of new developers, I put together some comprehensive training package targeted at new community members.

4.5 RC3 Test Day on Thursday December 4, 2014
