Call for Networking Topics

I’m getting ready to start a “Virtual Networking 101” series of blog posts, where I’m going to try to help introduce the ideas and concepts of virtual networking to VM admins that might not be familiar with these concepts. These are not deep dives; rather, I’m aiming to provide enough introductory knowledge that VM admins are who aren’t familiar with this stuff can at least understand what’s going on. However, I’ve been working in this stuff for a little while now, so it’s a bit difficult for me to tell what core/base concepts would really be helpful to others.

Announcing VMware vSphere Design, 2nd Edition

I’ve been phenomenally lucky to be involved in a number of book projects around VMware vSphere. I think that most people probably know me for the wildly popular Mastering VMware vSphere 4 and Mastering VMware vSphere 5 books (released at VMworld 2009 and VMworld EMEA 2011, respectively), but in late 2010/early 2011 I also had the opportunity to collaborate with Forbes Guthrie and Maish Saidel-Keesing on VMware vSphere Design. Even though that book hasn’t sold as many units as the Mastering books, it’s a work of which I’m equally proud. The topic of designing vSphere environments can be difficult to address, but I think we did a pretty good job.

Technology Short Take #30

Welcome to Technology Short Take #30. This Technology Short Take is a bit heavy on the networking side, but I suppose that’s understandable given my recent job change. Enjoy!

Automating Open vSwitch Configuration with Puppet

In this post, I’m going to show you a way to automate the configuration of Open vSwitch (OVS) using Puppet. While this method will work, it is not without its drawbacks (which I’ll explain later in the post). I freely admit that there might be better ways of accomplishing this task; this is one simple way that I discovered.

Modifying Virtual User Resources in Puppet

In an earlier post on using Puppet to manage user accounts, I showed how I was using virtual user resources to manage user accounts on Puppet-managed nodes. Today, I ran into a situation where I wanted one of these virtual user resources to have a different group membership on one class of nodes than on another class of nodes. In this post, I’ll show you how I managed to modify the group membership of a realized virtual user resource.

Exploring RHEL-OVS Integrations

In this post, I’m going to explore some integrations between Red Hat Enterprise Linux (RHEL)/RHEL variants and Open vSwitch (OVS). This post will lay the foundation for a future post describing OVS automation using Puppet.

Looking Ahead: My 2013 Projects

In early January 2012, I posted a list of my 2012 projects. Those projects included learning to script in Perl, learning German, becoming more familiar with Xen/Open vSwitch/OpenStack, and pursuing CCNP. In late June 2012, my mid-year project update let you know that I was dropping the Perl efforts, but sticking it out with German, Xen/OVS/OpenStack, and CCNP. (I later dropped Xen in favor of KVM.) Finally, in early January 2013 I graded myself on my progress on my 2012 goals. In this post, I’d like to take lessons learned from my 2012 projects and apply them toward my list of 2013 projects.
