Virtualization has been a buzz word for a few years now. Some people think it has been over-hyped but I'm not one of those people. The big competing products seem to be: VMware, Xen, KVM, VirtualBox, Parallels (including OpenVZ), and Hyper-V.
Is there too much choice out there? Choice isn't bad, is it? Will there eventually be a market shake up with a thinning of product candidates as a result? Will someone try to proclaim that they are the virtualization "standard"? I don't really know. I certainly like competition and don't think having a number of competing products is bad. There are both proprietary products and FOSS products. As you can guess, I lean towards the later if at all possible.
Update: Full article now includes two embedded flash videos from Red Hat.
Proxmox VE is a “bare metal” ISO Linux distribution that is a virtual machine platform. It is geared towards enterprise users and designed to be installed on enterprise grade hardware. The Proxmox VE distribution combines two virtual machine technologies; KVM and OpenVZ as well as a web interface to manage everything. Proxmox VE also integrates into its web interface a way to manage multiple computers as a cluster. For the rest of the article Proxmox VE shall be referred to as PVE. This article is written about PVE 1.1, the latest stable release.
Brian said he has been working in a Windows only shop and for the presentation he had installed Linux (Fedora 10) on his laptop for the first time in a long while. Glad to see it actually worked well.
It is nice when a presenter uses Linux to give their presentation at a Linux meeting, huh? He actually ran his slides from Powerpoint 2003 under Wine as one of several examples he gave of how well some apps work.
Attached you will find a PDF version of his presentation. Enjoy!
After being a guest on The Linux Link Tech Show back in December I asked Dann Washko if I he would be interested in allowing me to conduct an email interview with him for MontanaLinux.org. He kindly agreed. If you aren't familiar with The Linux Link Tech Show... pull your head out of the sand and check out their wikipedia page.
I was wondering just how many OpenVZ containers I could create on a beefy machine and how many processes the Linux kernel would be happy running so I decided to do an experiment.
I have two OpenVZ hosts... one is the primary and the other is a backup machine. Both of them are HP Proliant DL380 Gen5 machines with dual, quad-core Xeon processors, 32GB of RAM, 32GB of swap, and a 600GB /vz partition. I decided to use the backup OpenVZ machine for the experiment.
Wow, being a guest on The Linux Link Tech Show... with fantastic hosts Dann, Linc, Allan, and Pat... was great. I had a lot of fun. Yes, there were some technical problems at the beginning of the show that caused it to start a little late... and unfortunately I didn't have a way to boost my volume... and I don't know how it sounded live because I wasn't tuned into the live stream... but the archive recording isn't too bad. I'm guessing Dann cranked up the volume whenever I was talking.
For those who missed the live show, here are links to the .ogg and .mp3 archives:
I made a two-part screencast on how to build a Fedora Linux remix. The first video has some slides at the beginning that explains the process and then walks through it with a live demo. The second video boots the LiveDVD that was created, shows an "Install to Hard Drive" and then shows some of the features of the remix.
Why would you want to make a remix? Two common reasons:
1) You want updated install media that has all of the updates already applied. Given the fact that Fedora has a lot of package churn and a constant stream of security fixes, bug fixes and feature enhancement updates, their install media gets out of date pretty quickly. That is especially the case if you want to use an .iso image of the LiveCD media to make a LiveUSB out of.
2) You want more software included on the Live media than Fedora provides. The Fedora folks usually fill up a single CD but how about a LiveDVD with additional desktop environments, a slew of window managers, a ton of application software, and multimedia apps that Fedora won't include in the distro? That's what I make during the screencast... a custom LiveDVD with all of the updates applied and all of the additional software I want in a LiveDVD with a painless, quick install-to-hard-drive if desired.
Here is the end result. I boot the the LiveDVD image and even do an install.
The first "Introduction to OpenVZ" screencast that I did was over 1.5 years ago and it has become somewhat outdated... so I decided to make a new one.

Fedora 10 was officially released on Tuesday November 25, 2008. Since its release I have installed it on a number of machines and been running it as my full-time desktop. I added screenshots for the Syslinux boot screen, Plymouth in text mode, GDM, GNOME Desktop, GNOME Window Decorations, KDM, KDE Startup, KDE Desktop and KDE Window Decorations.
In March of 2005 Dr. Peter H. Salus started writing a book which he posted a chapter at a time on Groklaw. You may recall that Groklaw is a website that sprang into prominence after SCO filed suite against IBM. Part of Groklaw's goals were to analyse and report on the case and to help gather up historical information about the development of Unix and Linux (and everything related) such that it could be used to dispute the claims of SCO.
It appears that the SCO vs. Novell case has come to an end today.
Getting back to Dr. Salus' book, it is entitled, The Daemon, the GNU, and the Penguin: A History of Free and Open Source. A while ago I discovered the book on Groklaw and since it is licensed under a Creative Commons Atrribution-NonCommercial-NoDerivs License I gathered up the web pages and assembled them into a nice printable format (PDF) which you can find as an attachment to this blog entry.
Some years ago I purchased Dr. Salus' A Quarter Century of UNIX and really enjoyed it. Unfortunately I loaned it out to a student at Rocky Mountain College who was doing a report and don't think I ever got it back. Oh well, there are plenty of used copies for sale.
Give The Daemon, the GNU, and the Penguin a read. It is worth your time.
