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.

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.

Using Xen Project on OpenStack “Juno” via Libvirt

By Xing Lin

This document describes steps I took to setup a compute node based on Ubuntu 14.04 for OpenStack “juno”, using the Xen Project via libvirt approach. Openstack does not support this approach well as it is in Group C of the hypervisor support matrix for Openstack. You can hardly find any tutorial online describing this approach and this might be the first. Let’s get started!
