My Virtualization Primer


When I gave my cloud presentation earlier this year, I did indeed have about 10% of my audience walk out on my presentation by the end. I couldn’t really figure out why either. I thought that an overview of the cloud was a great topic to bring up among people that might not otherwise know much about it. Through repeated viewings of my presentation, I think I realize when I lost most everyone. I should have stopped after my cloud section and spent the rest of the time clarifying everything. Instead, I barrelled through the next section on virtualization with wild abandon, as if I was giving this presentation to a group of people that were already doing it. Instead, I should have split the two and focused on presenting virtualization in its own session.

When I got the chance to present again at the fall edition of this conference, I jumped at the chance. Here was my opportunity to erase my mistake and spend more time on the “how” of things. Coupled with my selection as a vExpert, I figured it was about time for me to evangelize all the great things about virtualization. If you are at all familiar with virtualization, this is going to be a pretty boring presentation to watch. Here’s a link to my slide deck (PDF Warning):

Here’s the video to go along with it:

Not my worst presentation. I felt it came off rather conversationally this time instead of a lecture. We did have some good discussion before the video started rolling that I wish I had captured. One of the things that really took me by surprise was the lack of questions. I don’t know if that’s because people are just being generally polite or if they’re worried about the quality of their question. I’m used to being in presentations at Tech Field Day where the delegates aren’t afraid to voice their opinions about things. I’m beginning to wonder if that is the exception to the rule. Even at other presentations that I’ve been to locally, the audience seems to be on the quiet side for the most part. I’ve even considered doing a TFD-style presentation of about two or three slides and the rest becomes a big discussion. I know I’d get a lot out of that, but I’m not sure my audience would appreciate it as much.

I’ve also noticed that I do need to start being careful when I’m in other presentations. In one that I attended two days after this video was made, I had to strongly resist the urge to correct a presenter on something. An audience member asked a question about BYOD security posture and classification and the answer that was received wasn’t what I would have wanted to get. I decided that discretion was the better part of valor and kept my mouth shut. What about you? If the presenter is saying something totally wrong or has missed the point entirely, would you say something?

Tom’s Take

In the end, most of it comes down to practice. When you assemble your slide deck and practice it a couple of times, you should feel good about the material. Don’t be one of those presenters that gets caught off guard by your own slide transitions. Don’t laugh, it happened in a different presentation. For me, the key going forward is going to be to reduce the slides and spend more time on the conversation. I’ve already decided that my content for 2013 is going to focus around IPv6. People have been coming to me asking about my original IPv6 presentation from 2011, and due to the final exhaustion of IPv4 from RIPE and ARIN, I think it’s time to revisit that one with a focus on real-world experience. That does mean that I’m going to have a lot of my plate in the next few months, but when I am done I’m going to have a lot of good anecdotes to tell.

  1. I Just finished watching both presentations in their entirety. Nice work revisiting this, the second one is more much more personable. If I was in the crowd I don’t think I’d have any questions either but I’d certainly want to get home and spin up some VMs of my own to play with.
