Today I finally got word that I will indeed be going to VMworld Europe 2010 in Copenhagen! I’ve done the registration process, so all that remains is to book the flight and hotel and I’m ready to go. To celebrate this, I’ve decided to announce a little contest; Where is Christian aka h0bbel? The first person to find me, as in the physical me, in the Bella Center during VMworld Europe 2010, (I’ll be there Tuesday - Thursday) will receive a free copy of the Trainsignal VMware vSphere Pro Series Training Vol.

We all know, and love, the fact that vSphere Hypervisor is free of charge. The free version doesn’t come with all the bells and whistles of the fully licensed product, but it’s still very usable in many scenarios. Recently I’ve been investigating the possibilities of running vSphere Hypervisor on a number of floating branch offices, also known as vessels. I’m not going into details about the proposed setup, and how we intend to roll it and so on, but one of the things I really wanted to get out of this was to have all my off-site vSphere Hypervisor installs appear in my vCenter Client.

Some topics seem to pop up at random intervals, one of them being virtualizing Microsoft Active Directory Domain Controller servers. The question is often either «Should I virtualize my Domain Controllers, and if so should I virtualize all of them?» or «Should I do a P2V (Physical 2 Virtual) conversion of my existing Domain Controllers, or create new ones?« In this post, I’ll be talking about the second question. While there is a lot to be said about the first one as well, I’ll leave that for future post.

In fresh blog post, called «Resource pools and simultaneous vMotions» by Frank Denneman prompted a quick Twitter discussion regarding the vCenter client (and perhaps even vCenter itself). A simple Why are there no folders under Host and Clusters view ? from Maish Saidel-Keesing got the ball rolling. Could it be that the design of the client itself helps perpetuate the myth the resource pools is an organizational unit, one that should be used as a way of grouping VMs?

When HP announced their new ProLiant MicroServer, I really hoped that it would be the perfect answer to a specific use case I’ve been looking at lately. Basically, what I’m looking for is a small chassis, low noise branch office server that would be used to host a single virtual machine, offering Read-Only Domain Controller (RODC) and Distributed File System (DFS) file-shares. Initially it looked to fit the bill perfectly:

During preparation and preliminary information gathering for a new internal project, I had a need to emulate various networking conditions and scenarios. More specifically I’m looking at the possibility of running the vCenter Client over high latency satellite links, with varying bandwidth availability and even packet loss scenarios. Obviously the best way of testing this, in a controlled environment, is to use some kind of WAN emulator that lets you control the various networking characteristics.

Dwayne Lessner who runs IT Blood Pressure, has written a guest post on GestaltIT called Is My Favourite VSphere Tool Is Going Away? In his article, Dwayne talks about vCenter Update Manager 4.1, and the fact that it seems to be the last version of the tools that will allow you to patch your Windows and Linux guests: VMware vCenter Update Manager Features. vCenter Update Manager 4.1 and its subesquent update releases are the last releases to support scanning and remediation of patches for Windows and Linux guest operating systems and applications running inside a virtual machine.

VMware has published a new whitepaper called VMware vCenter Server Performance and Best Practices. This is a must read if you manage a vCenter 4.1 installation, or are currently planning your upgrade. The whitepaper highlights the performance improvements in the latest version, sizing guidelines, best practices and some really good real world information from several case studies. One simple, but probably often overlooked tip, is that the amount of vCenter Clients connected to your vCenter Server has an impact on it’s performance.

Over at PlanetVM Wil van Antwerpen posted The Future of VMware Server back in May 2010. Wil makes the argument that it seems like VMware is indeed abandoning VMware Server as a product, leaving us with VMware Workstation and VMware Player as the two Windows installable virtualization solutions from the company. This has caused some reactions, including my own comment, where I question the smartness of abandoning what might just be one of the best virtualization «gateway drugs» VMware has to offer.
