I noticed Kir's blog post about the updated vzctl today. Cool! Finally I can create Fedora 14 containers... and the container restart mechanism has been fixed up too.
I downloaded the beta OS Template that the OpenVZ Projects offers for Fedora 14, created a container, did all of the updates, removed the samba* packages, added a few packages I wanted (mc, screen, links), and modified the httpd.conf so it is more like factory. Then I disabled a few services that aren't really needed... after all, who needs xinetd running when it it doesn't have any services configured? Then I stopped the container, cleaned up the container filesystem some, and tar.gz'ed it up and uploaded it as a contrib OS Template.
I did this for both the 32-bit and 64-bit OS Templates. Enjoy!
While investigating a bug in TigerVNC and noticing it was fixed in a recentupdate I discovered that there was a
tigervnc-license package. Just what is that? ...I wondered. When I found out I felt compelled to submit a bug report that I thought I'd share.
I'm not familiar enough with Ubuntu Development to know just how far this might go but at the very least it appears that some Ubuntu developers have identified as a goal to make LXC usable for production stuff and to put it on par with KVM.
The linux container tools (http://lxc.sourceforge.net) raised some interest for the community but there are crucial functionalities which are missing. The purpose of the session is to identify these missing functionalities and prioritize them in order to have a ready for production component for the Natty server delivery.
Make the use of containers for service segregation on par with KVM in terms of functionality and transparancy.
Joe is a system administrator who wants to start a temporary image to run postfix. To save on resources he runs it using a container. He wants to be able to update the image without fear of updates un-doing hacks needed for containers.
Jane is a system administrator who wants to be able to mix containers with KVM VMs through libvirt. She wants libvirt to auto-start containers, and virt-manager to cleanly shut down the containers.
So far I see identification of problems and need for various features... and a LOT of "todo" lists. I hope they get a significant chunk of that accomplished... so that it can filter back upstream and be used by other distros too.
There have been a few occasions where I have wanted to install CentOS on a remote machine that already had a working flavor of Linux on it. Luckily RHEL / CentOS has a way to do this.
- Download the PXE CentOS kernel and initrd image
- Configure the bootloader to boot the CentOS kernel by default
- Configure the bootloader with extra parameters for networking and remote VNC
- Reboot the machine
- Run the vncviewer in listen mode with port 5500 accessible
What is SPICE? - It stands for "Simple Protocol for Independent Computing Environments". What does that mean exactly? SPICE is a remote display protocol designed specifically for use with the Linux kernel's built-in virtualization hypervisor KVM. SPICE is similar to terminal services but rather than multiple users sharing a single, remote physical machine, SPICE allows you to graphically connect to and use a local or a remote KVM virtual machine.
For those who want to just watch a video, here it is. Please note that I kept bumping the tripod by accident and autofocus can be annoying in some spots... and it isn't the highest quality... BUT it does give you a good idea of how well SPICE works.
If you can't see it, your browser probably doesn't support the WEBM video format yet. Right-click on any of the links below (webm and ogv) and download. Then play the file you downloaded in a recent version of VLC.
I like to write reviews. I have written quite a few of them over the years... even back in my Atari days for a few print magazines. I mention this because while I'd like to write a review of the Fedora 14 release I feel like too much of an insider to be objective and I'd have trouble being as critical as a non-biased observer would be.
Yesterday I ran across a link on Fedora Planet for a video review on the Linux Action Show. I have watched a few of the LAS episodes before but am not a regular viewer... but since the topic of the episode was listed as "Fedora 14 Review" I decided to give it a viewing. About 33 minutes into it they get to the Fedora review... although it is hard for me to call it a review. It is unfortunate but they started with the Fedora 14 Release Announcement and used that as a basis for their review. Historically release announcements are very brief documents that give only spartan details but include links to other sources of more complete information, like the Fedora 14 Release Notes for example. Given the fact that the release announcement only states two new features for desktop users (libjpeg-turbo and Spice) it seems they assumed that was all there was to the release, given the fact that their main focus is desktop usage. As a result they spent most of their review time in ridicule mode... divided in two... with both an attempt at humor and at a "wake up call" style denouncement of everything Fedora. They even included an original conspiracy theory.
I think everyone who knows me understands I have a pretty healthy sense of humor that can sometimes go to the dark side... but I found almost nothing about their show funny. I'm guessing some people find their show hilarious... but me... and this episode... I'd say frustration was my reaction.
I did get on the Linux Action Show IRC channel (the only form of contact on their contact page that I use) for a few minutes and discuss with someone (probably not them) that it was unfortunate that Bryan and Chris had chosen the very brief release announcement as the authoritative source of "what's new in Fedora 14" rather than the release notes... but I do concede that the release announcement could have been much better than it was.

I've been following the development and building my MontanaLinux remix every so often, usually after a bunch of updates. All in all, I'm pretty impressed with the release.
If you know where to find the RC1 release, which is freely available, that is the final release (to the best of my knowledge). So if you want Fedora 14 early, download that. I did, although I'm mainly using my remix.
Someone at work passed around the parting memo of a Microsoft technology leader... to spark a discussion on what we see as future trends in technology. I made a long reply so I thought I'd duplicate it here.
I've been watching The Colbert Report since episode one from five years ago... and I see sites like crooksandliars posting videos from TCR and The Daily Show all the time... so I assume it is ok to post... but if someone from Viacom says otherwise, I'll gladly take it down.
Anyway, Nicholas Negroponte was a guest and although there isn't much real content for us Linux / OLPC knowledgeable folks, it is still fun to watch. Embedded is the webm version.
