VMware Vulnerability
This article was sent to me over the weekend. It seems that VMware is no longer immune to ransomware. If you did not believe me before when I told you that patch management was one of your most important defensive weapons in the fight against cybersecurity incidents, please believe me now! Massive ESXiArgs ransomware attack…

Server Core on VMware
When I was a Virtual Technical Evangelist for Microsoft Canada I spent a lot of time telling you why you should use Server Core… especially if you were on Hyper-V. Why? You save resources. It is now over two years since I turned in my Purple Badge, and I still think Server Core rocks. In…

Virtual Machine Snapshots: The useful tool that will drag you down.
Note: Once again I accidentally scheduled a technical article to publish on a holiday. In honour of Canadian Thanskgiving I am republishing this article on Tuesday. -MDG The Story: One of my clients called me and asked me why some of their servers were running so terribly slow. Actually, that’s not entirely true… they told…

A VMware Gripe
Okay, I can’t delete a file. Any Level 1 systems administrator would look at this message and say: ‘Okay, VMware is not allowing me to delete an ISO file. Very likely the ISO file is connected to a virtual machine.’ Ummm… but WHICH virtual machine is it? Gee thanks, vCenter, I have scores of VMs……

Hyper-V 2008 R2: Still good enough?
I manage a vSphere environment at work, and it is a real change from the last few years when I spent all of my time talking about Hyper-V. I want to be clear – it is not better or worse, it is just… different. We have a number of virtualization hosts, plus a physical domain…

Counting Down the Classics with the US IT Evangelists
“On the first day of Christmas my true love gave to me…” “Ninety-nine bottles of beer on the wall…” “Thirty-five articles on Virtualization…” All of these are great sing-along songs, whether for holidays, camping, bus-rides, or comparing virtualization technology. Each one is a classic. Wait… you’ve never heard the last one? That’s okay, we…

Hyper-V CPU Compatibility Mode
it is pretty well known that for Live Migration to work in Hyper-V, the CPUs on the hosts must be of the same family (Intel to Intel, AMD to AMD). However it is not as simple as that. Both companies are constantly improving their products, so a CPU that Intel makes in 2013 will have…

Back on RunAs Radio!
Over the past few months I have recorded a number of webinars and webcasts on a plethora of topics around virtualization, but the one that seems to have gotten the most attention is the one I did for VMTraining that pitted me against Jeff Weiss – Microsoft versus VMware. A few days later Richard Campbell,…

vSphere vs. Hyper-V: The Head to Head Battle!
On Thursday August 8th I participated in a webinar debate. Shawn MacArthur (CEO of VMTraining) and I had a friendly debate over which hypervisor and virtualization ecosystem was better. This was the third part in the series – The first had Shawn discussing vSphere, the second had me discussing Hyper-V and System Center. Who won? …

Two champions, both undefeated, and the winner will be… YOU! VERSUS As many of you know I used to (and occasionally still do)…

Calgary Here I Come!
Even before joining Microsoft Canada’s DPE team as a Virtual Evangelist (the Virtual part means I am a contractor in case you were curious, but I also specialize in Virtualization so it works in my favour!) I have had the opportunity to crisscross our great nation talking to audiences of all sorts and sizes –…

System Center VMM Supported Hosts
When I was asked in class recently what type of virtualization hosts are supported by System Center 2012 though Virtual Machine Manager I readily answered off the top of my head. Unfortunately one of my students went on-line to search for confirmation of this, and came up with a TechNet article that gave a conflicting…

In interesting survey from VMworld…
I have a lot of conversations with people about virtualization… it’s what I do (well, among other things). While most people agree that I am technically knowledgeable on both Microsoft and vSphere virtualization, sometimes my analysis and commentary strike people as skewed and unrealistic based on my relationship with Microsoft. For the past couple of…

It’s Coming… Can we now compare Hyper-V with vSphere as both new products prepare for launch?
On July 5th I published an article titled A Response to VMware’s ‘Get the Facts’ page comparing vSphere to Hyper-V & System Center’. In the seven weeks since it went live it has become the 4th most read article I have ever published (in seven years as a blogger), as well as being by far the…

Is it true? The Memory Tax is gone!
CRN is reporting that next week at VMworld VMware will be announcing that they are doing away with Virtual Memory Entitlements, which you have probably heard me refer to as the Memory Tax. According to the article (http://www.crn.com/news/cloud/240005840/vmware-kills-vram-licensing-will-focus-on-vsphere-cloud-bundles.htm?cid=nl_alert) VMware is trying to regain its competitive edge over Microsoft’s Hyper-V, which has over the past couple…
