Background In my original post KVM Virtualization 101 and my second post KVM Virtualization 102, I explained some basic commands that are necessary to get on using KVM and some features for tuning KVM. In this article I move on to some of the more advanced problems when converting existing Linux machines from a
KVM Virtualization 102
Background In my original post KVM Virtualization 101 I explained some basic commands that are necessary to get on using KVM. In this article I move on to some slightly more obscure topics in using KVM. Routine Operations CPU Type When you are operating in a KVM virtual machine the processor will report
Bootstrapping and Rooting Documentation: Part3
Background In Part 1, I described a method of documentation where the introduction of the system is made using the documentation. This builds consensus, enculturates an operations group, and provides a platform unto which more automation can be built. In Part 2, I elaborated on the ideas of Bootstrapping & Rooting, Self Service Culture, and

The Systems Administrator’s Lab
Recently, I listened to an O'Reilly webcast called "The Myths of Innovation" where Scott Berkun discussed the concept of a lab. He showed a picture of Edison's lab which showed wooden tables, lamps, and beakers. Systems administrators are also inventors. We are required to script, program, and configure exotic servers and equipment. To discover new solutions, we need a lab. This is especially true with cloud computing and virtual infrastructure where machines are created and destroyed in a very transient manner. You need a lab to track all of the successful and failed experiments.

Linux Systems Administration: Does it Have to be Boring
Abstract Linux Systems Administration for Power Users: This presentation was created for the Oct, 2010 Akron Linux Users Group. This presentation is given from the angle, what do I do when I am in a bind. At some point all computers break. Since Linux is fairly stable, it can be intimidating when something important does

KVM Virtualization 101
Background For those of you who are familiar with virtualization, KVM is a hypervisor which is built into the Linux Kernel. This allows a Linux desktop or server to simulate multiple pieces of hardware, which can then have different operating systems installed. KVM uses the QEMU virtual machine format. QEMU may be familiar to those
Ohio Linux Fest 2010: Recap
I had an awesome time at Ohio Linux Fest 2010. I met a lot of interesting people, caught several really good talks and had a chance to take the LPIC 101 and 102 tests. It was a great mix of hobbyists, systems administrators and programs and I took it as an opportunity to expand my
Bootstrapping and Rooting Documentation: Part 2
Background In Bootstrapping and Rooting Documentation: Part 1, I laid out a blueprint for using documentation as the bootstrap for entry into an operations environment. In this article I will dig into the three main concepts mentioned in Part 1. In Part 3, I will demonstrate our use case for a data center of about
