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.

The Linux Foundation has put together a 20th Anniversary of Linux Gallery with a timeline and a lot of donated items from various companies and members of the Linux community. As luck would have it, I ripped this from youtube so I could repost it in webm format and noticed that in the original the metadata for the audio stream said -
creation_time : 1970-01-01 00:00:00. While that isn't quite true for Linux, which was started in 1991, it is basically the Epoch time considered to be the start of the UNIX universe. :)

It is my impression the Linux users and Distros are sitting on our hands. We seem to have arrived.
I wonder how many new Linux users are out there now? I pull down three Linux Users Groups and it has been a long long time since I saw a new user asking questions. I have been using Linux since about '95 or so, and with my aging problem (memory loss) I always learned a lot at users group meetings. Now it seems to me the recent presentations I have noted are very specialised. Not the general subject about Linux.
Have we, The Linux Community, given up trying for new users?
I'll give my response and I encourage everyone to reply with theirs too.
2011 marks the 20th anniversary of the creation of the Linux kernel. But when exactly was it created? One of the first milestones we have was the original comp.os.minix newsgroup posting that Linus wrote announcing his unnamed new OS. Here's a recreation of that posting:
From: torvalds@klaava.Helsinki.FI (Linus Benedict Torvalds)

Subject: What would you like to see most in minix?
Hello everybody out there using minix - I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I'd like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).
I've currently ported bash(1.08) and gcc(1.40), and things seem to work. This implies that I'll get something practical within a few months, and I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them :-)
PS. Yes - it's free of any minix code, and it has a multi-threaded fs. It is NOT protable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that's all I have :-(.
So that post was sent out on August 25 but it is obvious that Linux has been around for a while... since April... but when was it started? I'm sure a better history is documented somewhere. I guess I'll break out one of my copies of Just for Fun and see if I can find it.
I'm not even sure at what point working name was changed from Freax to Linux. Note that in Linus' post, he doesn't give it a name. I welcome comments from others on what they remember! I started using Linux a little late myself... in January of 1995.
Oh... and it sounds like a good reason to have a party... but when and where? Anyone?
This is a quick video from The Linux Foundation. It is just a little over one minute long and compares Operating Systems to cars.
I am a PC, Mac, and Linux user. At night I dual boot between Vista and Ubuntu and during the day I use a Mac almost exclusively. As a result, there are many things I like about using my Mac at work and would not mind seeing them on my home desktop. Since buying a Mac right now for personal use is out of the question I have to make do with what I already have. At any rate, one of the Mac features I actually like is the Dock.
If you are reading this it is because I finally got around to taking Scott up on his request for Ubuntu content. I am not a well versed Linux user and over the years have had a love/hate relationship with Linux and the open source community. My beef is not with proprietary software as much as it is with outrageous pricing and no access to the code to make it work for you. I don’t believe Microsoft or Apple are 100% evil nor do I think that Linux or open source are always the best solution for the job - nor do I think Microsoft or Apple are always the best solution.
I wrote a rather long response to a posting I saw on Fedora Planet entitled, "Death of the Year of the Linux Desktop". I'm sharing it here as well.

The desktop is dead? Some disagree. See this very compressed video on the "Death of the Desktop":
What makes someone a winner and what makes someone a loser? Linux on the desktop has tens of millions of users. While that might not be double-digit market share it is still a significant number of users. Anyone who looks at those numbers and calls them losing must have thought the game was winnable to begin with. It wasn't. FOSS does not spend hundreds of millions on advertising and billions on under-the-table deals with hardware makers... FOSS simply does not operate on the same playing field. The free hand of the market happens to be attached to a twisted arm.
In reality there aren't any winners and losers because it isn't a race. While those who are in it for money have certain ways to measure success, in FOSS you just make the best software you can and hope users will appreciate it. Of course the squeaky wheels always make the most noise and there are lots of complainers out there (see discussions on KDE 3.x vs. 4.x as an example) but that doesn't mean that vast majority of us FOSS users aren't very happy.
I found this video fascinating (although the editing is a bit erratic) so I decided to share it. I personally do not see the personal desktop (hardware nor software) dying any time soon.
There is a lot of passion in the discussion and as a result some passionate words are used that some might find offensive... so be prepared.
What do you think?
Just got done reading, "Confessions of an Ubuntu Fanboy". While I'm glad the author has decided to be more practical in his promotion of Linux and Ubuntu, I strongly disagree with some of his conclusions and I'll cover them below.
I have been using Linux for about 15 years now and over the course of that time I've helped more people than I care to count with Linux installs, removals and everything in-between. I've seen people try Linux out for a few days and give up on it. I've seen people tough it out and become valued members of our local Linux community. Linux isn't for everyone and choice is good. I no longer advocate Linux for someone who isn't willing to learn new things. I quit trying to push it on people and now I'm somewhat selective in helping people the second they say they want to try Linux. I state up front that there is a learning curve and that they will need to expect it. If I sense that they don't have patience to learn new things, I don't even bother.
The problem with the article in question is that the author seems to want to try to make Linux for everyone and in doing so, he advocates violating some important tenants. He primarily focuses on Windows users but it could be any proprietary OS or applications.
