My first VMUG presentation

I did my first VMUG presentation at the Danish VMUG meeting on April 3., in Palads Biograf in Copenhagen.
For a summary of the day, go read Terkel Olsen’s blogpost: “Great VMUG Meeting in Denmark”

My subject/title was “100% virtualized on Apple hardware”, which I had 30 minutes to talk about. I was scheduled as the second speaker of the day, just a short break after Tommy Drægert from BitDefender.

I had done some presentations before, for maybe 30-35 people.
At the Danish VMUG meeting there were around 100 people in the cinema, so I was naturally a little nervous. It might also have had something to do with the fact that I decided, like 20-25 minutes before my presentation, to translate my complete slide deck from Danish to English, and also do the speaking in English instead of Danish.

The reason for the drastic change occurred during Tommy Drægert’s session which was in Danish. Scott Lowe (who was there to give a session about NSX, later in the day) commented on Twitter that it was strange to be at a VMUG meeting and be unable to understand what was being talked about on stage.
It then occurred to me, that beside my own session, the rest of the day would be in English by foreign guest speakers.
I then suggested on Twitter that I could do the presentation in English, but that my slides would be in Danish. A few people commented on Twitter that it would be a nice gesture for the foreign speakers.
When Tommy Drægerts session ended there where a 30 minute break, for coffee and socializing.
During that break I opened up my slides, and quickly looked through them, and decided to do a quick translate. (luckily my slides were simple with only little text and I only had around 20 slides).

So fast forward 20-25 minutes and I am on stage with a English slide deck and ready to do a presentation in English :-)

My presentation went very well, people seemed interested in my topic and asked a few questions when I was done with the main part of the presentation.

My slides are available here in PDF format:
100 procent virtualized on Apple hardware

Just to be clear, my presentation was originally scheduled to be in Danish, and the VMUG leaders said afterwards that it would have been totally fine for me to do it in the Danish.
So it was my own personally decision to do the presentation in English.

I had a great time on stage and had some good interactions with my fellow VMUG’ers in the breaks after.

If I am given the opportunity I would love to do it again.

Below I would like to give a few suggestions for first time speakers, and also give a little feedback to the VMUG leaders.

Suggestions / recommendations for first time speakers:

  • Make you slides as simple as possible, with as little text as needed. Tell your story, instead of letting the audience read it.
  • Know how your computer needs to be configured, when hooking it up to a projector. Time is limited just before your presentation.
  • Be on time, and get on stage as soon as you are allowed, so that you can get your computer hooked up, without getting stressed about that part.
  • Rule of thumb: No more than 1 slide per minute. So if you have 30 minutes to present, you should not have more than 30 slides.
  • Leave room for questions at the end. So make your presentation a few minutes short, thereby a few slides less than your scheduled time.
  • Look at the audience, instead of your computer-screen (or worse the projector-screen).

Feedback for the VMUG leaders:

  • If available, provide information about projector resolution and connectivity as soon as possible.
  • If possible, please pre-register speakers, and inform the speakers that they have been pre-registered for the event.

Virtualize OS X using vSphere on Mac hardware

Just a short announcement that I have written a blog post on my employers blog, called “Virtualize OS X using vSphere on Mac hardware”.
In the blogpost I try to answer the following questions:

  • What is required to vitualize OS X?
  • Which hardware is supported, and which hardware works?
  • How to license OS X in a virtual environment?
  • What are best practices for running OS X in a virtual environment?
  • How to safely deploy OS X from a template?
  • How to backup OS X in a virtual environment?

Head over to the bmspeak blog to read the post:

vCenter 5.5 install fails during vCenter Server Directory Service installation

Today I was installing a new vCenter 5.5 server for a customer,
on a freshly installed Windows Server 2012 VM, which would also be hosting the Micrsoft SQL database locally.

I had already joined the server to the domain and setup Micrsoft SQL Server 2012 SP1, and created the vCenter Database,
and an accompanying System DSN, so I was ready to do the vCenter installation.

I chose to install using the Simple Install method, because… well this was a simple installation.

SSO, vSphere Web Client and Inventory Service all installed with any issues.

But during the vCenter Server installation, I got a error Continue reading

VMworld Europe 2013 – Day 1

VMworld Europe 2013

I arrived in Barcelona sunday night with my colleagues, Heino Skov and Brian Markussen, and couple of customers.

Sunday night, we had a few beers, which where payed by the nice people from Avnet.
Many of the danish VMworld attendees where there, and we had some good talks.

This morning we got registered at the conference center, and got our badges and bags.

During the day, I have talked with a lot of people in the VMware community.
Also been by the Hands-On-Labs, and took two labs, vSphere Distributed Switch from A to Z (HOL-SDC-1302) and Virtual Storage Solutions (HOL-SDC-1308).

Later I will attend the Parter General Session, and then go out to the Businessmann arranged dinner, with the colleagues and customers.

I am very much looking forward to the coming days and sessions.

Avoid issues with backup of WordPress using BackWPup

I have used BackWPup in the past to do backup of this WordPress based website, but recently I encountered some problems.

In my original BackWPup setup there was a simple BackWPup-job that just created a ZIP-archive of everything WordPress related at my webhost, One.com, and then sent that ZIP-archive to my Dropbox.com account for offsite storing.

But recently I started receiving error-emails, that the backup did not finish correctly.

Creating a never booted OS X template in vSphere 5.1

Page 1 – Introduction and reason for doing this

The goal of this blog post is to produce a never booted installation of OS X Mountain Lion, in a VMDK, which can be used as a template in VMware vSphere vCenter 5.1.

The reason for doing this, is that when a OS X installation is done the normal way, using the Installation GUI, then on the first boot of the newly installed machine there is created a bunch of machine specific files and items.
These machine specific files and items, e.g. the Local Kerberos Key Distribution Center (or LKDC), needs to be cleaned out, if the installation is going to be used as a template, either in VMware vSphere or using traditional image deployment techniques.

Instead of doing the installation using the normal GUI procedures, it is possible to install OS X into an empty DMG image file, and therefor the installed version of OS X is never booted, and thereby the machine specific files and items are never created. Leaving you with a pristine and untouched version of OS X, ready to be booted for the very first time, when deployed.

During this blog post I will walk you through how to do all this, with detailed instructions and screenshots.

Save CPU time, disable Screen Saver on Mac OS X VMs

By default Mac OS X comes with the Screen Saver enabled, and set to kick in after 20 min. This is good in the physical world, to avoid screen burn in and somebody watching. In the virtual world, it does not make much sense, because there is no screen, so no risk of screen burn in or for that matter somebody watching. But besides the above mention reasons, there is another reason to disable the Screen Saver in Mac OS X VMs. And that is the CPU utilization when the Screen Saver is running.

Some advise on deploying the Kerio Control Virtual Appliance

At my workplace, Artwork Systems Nordic A/S, we have previously used the Kerio Control Box 3110, as our firewall.

But do to that we have virtualized the main part of our servers, we decided to do the same with our firewall.

Kerio provides the Kerio Control product as both a Hardware Appliance, a Software Appliance and a Virtual Appliance.
