Jan 30: TRAIL: Server virtualization (specifically Linux/Xen)
Recently, I've been very interested in server virtualization. Specifically, I've been interested in virtualizing Linux using Xen. I've been reading a ton about it, and have compiled the following trail. It starts with the more general (what is virtualization, theory, examples, etc.) and gradually becomes more specific (Xen info and howtos).
An Introduction to Virtualization
This is a rather long and in-depth look at what exactly virtualization means and why you'd want to use it. The author includes short descriptions of many different ways of achieving virtualization. Sadly, he doesn't delve into Xen, but I think that's because at the time of writing Xen was relatively new.
Virtualization -- Short introduction to virtualization techniques
Basically, this is just a bare-bones intro--not as in-depth as the previous article. It presents short explanations of the three main virtualization techniques and gives examples of each.
Exclusive: Xen Grows Up
This is a really good article that discusses Xen, describes how it works, how you can use it, and how it compares to other virtualization techniques. Sadly, it requires a username and password, but the one I got from BugMeNot works just fine.
Ok, enough with the theory and intros. On to the howtos and tutorials!
The Perfect Xen Setup For Debian And Ubuntu
A very in-depth, step-by-step tutorial on installing Xen on Debian or Ubuntu. It has this helpful note at the beginning:This is a "copy & paste" HowTo! The easiest way to follow this tutorial is to use a command line client/SSH client (like PuTTY for Windows) and simply copy and paste the commands (except where you have to provide own information like IP addresses, hostnames, passwords,...). This helps to avoid typos.
Debian Administration :: Installing Xen 3.0 upon Debian Sarge
Debian Administration :: Installing Xen 3.0 upon Debian Unstable, with a custom Kernel
These are two tutorials on installing Xen in Debian from the great Debian site, Debian Administration. Both are by the site's maintainer (and Debian developer), Steve. The first one describes installing Xen using one of the stock Debian kernels. The second one describes the process for installing a custom-compiled kernel in the Xen instances. It also touches on using the xen-tools script (written by Steve) to automate the installation of a basic Xen instance.
Note: I've got a few more articles (two about clustering Xen, and one about using multiple Xen instances to create a virtual network for testing), but they're outside the scope of this trail. So, I'm posting them to my del.icio.us/xen page in case anyone is interested.

Sep 27: Trail: Bill Frist stock sale scandal
My first Trail is about the current Bill Frist potential stock sale scandal.
WP: Senator Sold Stock Before Price Dropped (9/21/05)
Senate Majority Leader Bill Frist, a potential presidential candidate in 2008, sold all his stock in his family's hospital corporation about two weeks before it issued a disappointing earnings report and the price fell nearly 15 percent.
WP: SEC, Justice Investigate Frist's Sale of Stock (9/24/05)
A spokesman said Frist's office has been contacted by both the SEC and the U.S. attorney's office in Manhattan about his divestiture of the stock. HCA disclosed separately that it was subpoenaed by the same U.S. attorney's office for documents that were related to Frist's sale. Frist and HCA said they are cooperating.
Jonah Goldberg (9/24/05)
My guess is that this stock sale stuff will ultimately fizzle out, mostly because I doubt Frist is so stupid as to do what some allege. But I see nothing wrong with the appropriate agencies investigating Frist's blind-trust stock sale.
WP: Frist Issue Adds to GOP's Ethics Troubles (9/25/05)
...said Nicholas E. Calio, a former aide to both Presidents Bush. "To me, it's inconceivable that he [Frist] would sell stock based on inside information. He doesn't need the money."
...
Frist, asked in a January 2003 TV interview whether he should sell his HCA stock, replied that his assets were in a blind trust and, "as far as I know, I own no HCA stock." Referring to his trust and those of his family, he added: "It is illegal right now for me to know what the composition of those trusts are. So I have no idea."
Democrats.org (9/26/05?)
Frist has claimed he sold the stock in HCA Inc., founded by his father and brother (who still sits on the company's board), to avoid any conflict of interest. He has not identified what new conflict has arisen that did not exist for his previous 10 years in the Senate.
Statement by Senate Majority Leader Bill Frist (9/26/05)
An examination of the facts will demonstrate that I acted properly. I will cooperate with the Securities and Exchange Commission (SEC) and the U.S. Attorney for the Southern District of New York to provide the information they need as quickly as possible. My only objective in selling the stock was to eliminate the appearance of a conflict of interest. I had no information about HCA or its performance that was not publicly available when I directed the trustees to sell the stock.
Documents: Frist knew contents of blind trust (9/27/05)
Blind trusts are designed to keep an arm's-length distance between federal officials and their investments, to avoid conflicts of interest. But documents show that Senate Majority Leader Bill Frist knew quite a bit about his accounts from nearly two dozen letters from the trust administrators.
If I read anything else that adds anything interesting to the discussion, I'll update this post with it.
Update: I just found this: Frist Stock Timeline. It's a lot more thorough than what I've presented above, so it may be a better resource. I'm not really shooting for a comprehensive review with these trails, though. I'm more shooting for a thorough overview of a subject. In that respect, I think I've delved a little too deep into the details with this first one. It's the first trail, though, so I expect that this feature will evolve as I post more.
Sep 27: New Feature: Trails
Linux Magazine recently introduced the idea of trails on their website:
Linux Magazine introduces trails. A trail is a series of links that deeply explores a topic or technique, drawing on a combination of new material, existing content from the Linux Magazine archive, and pointers to examples and additional articles on the Web.
I've decided to blatantly steal that idea and introduce trails here on furiousBlog. Their trails look to just be links to old articles on their site (a clever way to drive ad views, but not necessarily to better inform or educate). Mine will be links to articles that I've read about a particular topic that will hopefully explain the topic thouroughly. I see it as an easy way to link to articles that I find interesting, but about which I don't have much to add (due to either stupidity or laziness).
I've added a Trails category, so that you can see all of the trails I post. All trails will be posted under this category, as well as the appropriate category for the topic discussed.
I'm working on the first one, so look for it soon.
