Getting Started with KVM

I always say I’m working on developing sharper skills for the world of Linux administration — and it’s true. All of my training efforts are focused on Linux for the eventual taking of the RHCSA exam. The process is going slowly, and when I ask myself why I’m moving slowly, the answer is two fold: 1. I have other projects going on that take time. 2. My goal isn’t to memorize facts or procedures and try to pass a test.

Item 1 is obvious. Item 2 is a conclusion I’ve come to over the years. While I do study concepts specific to the RHSCA, I am trying to incorporate using them in my home lab, so I can get a feel for using them in an actual Linux administration job. The alternative learning concepts in some kind of vacuum and never seeing how they can be applied to “real” scenarios.

I’m not going to chronicle every step, but as I learn new things, I’m going to take some opportunities to produce tutorial videos about them for the Youtube channel. One such video is below. Now I’ve been using KVM in my lab for a while, but I want to dive a bit deeper into it. For those just starting out with KVM, this tutorial will get you up and running, as well as giving a brief explanation about the “why” involved with the tasks that have to be done.

Bare Metal Server? Only Install a Hypervisor!

MangoCon was successful, and last week was super busy: two Peachtree Symphonic Winds concerts. At last, I have time to get back to my RHCSA study as well as back to making videos for YouTube.

Even though virtualized infrastructure is now the norm, no matter what size of business, the question still comes up about what should be installed on the bare-metal of the server. A server OS? A hypervisor? Something else? In my opinion, the answer is “a hypervisor.” In the below video I talk about two reasons why.

MangoCon 2019!

The last week and a half have been quite busy from general at-home tasks to recording the GMEA District 13 First Year Honor Band event. This week I’ll be at Mangocon 2019! If you’re coming there, I’d love to meet you. Look for the guy who looks like person in the below video :).

More content will be coming to YouTube soon once MangoCon is over.

The Cost of Keeping Software Current

In this video I discuss why it’s important to consider the cost of keeping your software current. Expensive problems can often be prevented by keeping your software up-to-date.

For example, I’ve seen situations where a business application wasn’t kept current for years. This application ran on an old operating system. Eventually the business is faced with the fact that the OS must be upgraded / replaced since it’s no longer supported. The problem is there’s no upgrade path to current for either the OS or the application, since what the business is using is so far behind. The cost of “starting over” with the application and OS while trying to not lose historical data is far greater than it would’ve been to keep the OS and application up-to-date.

YouTube Channel Launch

As the title suggests, I now have a YouTube Channel! Sometimes, it’s easier to discuss topics with voice and video rather than text; however, I will still contribute to the blog. I hope you find the content relevant and useful, and I’ll try to keep the topic scope limited to IT and Music.

Enjoy the first video!
