Sometimes the path to learn something means using very different tools along the way. In my case, I have been learning more on the developing virtual network world along with some of the new DevOps toolsets popping up. As part of this I have started using KVM as a hypervisor on an Ubuntu 11.10 platform in a portion of my home lab. I have learned quickly that getting something simple done in vSphere can be a bit of a chore in the KVM world. But on the flipside, KVM has been a fun learning experience in understanding virtualization in a more raw format. One of these challenges I have decided to share is a simple one. I was wanting to play with the Dell-created DevOps deployment tool: Crowbar. Crowbar is an wrapper for OpsCode Chef Server. While a pretty slick little utility to research in the cloud deployment and automation space; one glaring problem is it is designed to run on Dell PowerEdge servers. Since I don’t have PowerEdge servers lying around anymore I needed to run this in a virtual machine. This in itself isn’t a huge problem as a virtual machine can pretty much match most of the logical hardware pieces needed. But, the one problem I ran into was that Crowbar out of the box likes to have a couple interfaces with the ability to tag VLANs itself. In a bare-metal world connecting 802.1q trunk ports to a server is pretty common. And even in the VMware [...]
In my career I was a late starter and fast riser. It wasn’t too long ago I was plugging in monitors and crawling under desks (a job I still highly respect). I owe a lot of my success to my supportive Wife who while she was raising my children, let me spend hours reading complete histories of LAN switching or reference book on WAN protocols. Not to mention every RFC under the sun. I owe a lot to my aggressive nature of never losing a fight whether it was an annoying Outlook bug, or an 801.X config that wouldn’t work right. But I also owe a lot to the technologies that I invested my time and effort behind who ultimately made my career. I bet on certain companies and technologies and they came through for me time and again. And so in this short blog post, I want to say thanks. So here are my thanks to the top 4 companies that have made me valuable by staying valuable in the information technology arena. 1. VMware My first experience with VMware was very early on from listening to a Dell solution architect talk about where they were going. This was back when vMotion was just a rumor and still seemed impossible. I went on to work for a company that did a big virtualization shoot-out. At the end of the shoot-out my recommendation was VMware. I was strongly impressed by their focus on stability and running at the enterprise level. [...]
Why not use the front panel LCD on newer Dell servers to list what VM’s are residing on the host?
