Lance Albertson from OSUOSL talked about Ganeti:

Screencast: Virtualization Basic Introduction

| |

I was asked to put together a presentation on Virtualization... and wasn't quite sure what the audience would want... so I put together a basic introduction that I can easily improvise on as the audience asks questions.

I designed the slides using Prezi which is a freemium web-based presentation site. It has lots of motion so watch out... but I did keep it rather simple - no pictures nor embedded videos. :)

Screencast: History and differences of Xen and KVM

| | | | | |

I threw together a quick screencast for Dann from the Linux Link Tech Show explaining the history of and differences between Xen and KVM. Feedback is encouraged because I'm sure I have some mistakes in there.

Videos: KVM Forum 2011 Presentations

| | | | | | |

The KVM Forum 2011 was held at the Hyatt Regency in Vancouver, Canada on August 15-16. It was co-located with LinuxCon North America 2011.

LinuxCon and the KVM Forum were both sponsored by The Linux Foundation who recorded a large number of videos from both events. Unfortunately, The Linux Foundation had few security breaches to deal with on their kernel.org and linux.com domains which (I'm guessing) has greatly delayed them doing post-production work on the recordings and posting them publicly.

I found that Red Hat had recently posted a handful of the KVM Forum videos to YouTube but since they were only available in the flv and mp4 formats, I decided to re-encode them and post them to archive.org as webm (a free, open source, non-patent encumbered video format). I think archive.org is really a better place for them. Red Hat released them under a Creative Commons, Attribution - No Derivative Works 3.0 License. I have not altered the videos in any way other than re-encoding them to webm in a smaller resolution (624x352) and bitrate (664Kbit) making them one half to one third of the original filesize yet maintaining reasonable quality. Modern Firefox, Google Chrome, and Opera browsers can play webm as can stand-alone players like VLC, Totem, and mplayer.

They are all highly technical presentations for those interested in the nitty-gritty details of the Linux KVM virtualization Hypervisor. I have embedded the first, short keynote video below and given download URLs for the rest. Thanks to Red Hat for posting them!

One thing to note is that the camera / recording is statically positioned and does not show the presenter slides so I have also included the links to the slide decks in PDF format. For a better understanding, you are strongly encouraged to look at the slides while watching the videos. Also be warned that some presenters may occasionally use curse words.

Here's a zip file containing all slide decks in PDF format for all of the presentations.

OpenNode Status Update

| | |

I don't usually repost mailing list messages but just got this one in my inbox from the OpenNode folks. Since I'm a big virtualization geek, I'm sharing. Haven't heard of OpenNode? Here's a brief description before I get to the status update email:

OpenNode is a open source server virtualization solution providing easy to use (CentOS / RHEL based) bare-metal ISO installer and supporting both OpenVZ container-based virtualization and emerging KVM full virtualization technology on the same physical host.

So, OpenNode is a lot like Proxmox VE except OpenNode is based on CentOS and uses libvirt, virt-manager, and other Red Hat standard tools.
