Microsoft responds to VMWare’s FUD

by Bharat Suneja

Much as I love blogging, I’m quite enjoying this unannounced break the past 3 weeks or so! A lot of interesting news, events (including TechEd 2009 in L.A.) and tidbits over the past weeks, and I’m sure you’ve kept up with it. (Incidentally, this also happened to be the first year in a long while when I actually took a break from TechEd!) What prompted me to end my unannounced break is the rather interesting turn the VMWare FUD has taken, with Microsoft’s Jeff Woolsey, Principal Group Program Manager in the Windows Server Hyper-V team actually responding to VMWare on the Virtualization team blog.

Let’s take a few steps back and look at the sequence of events.

Hyper-V Wows IT Pros and Critics Alike
It’s no big secret that Microsoft’s Hyper-V virtualization platform has wowed users and critics alike in its very first release. ZDNet’s Mary-Jo Foley posted a review of the pre-release Hyper-V code (by Jason Perlow):

Even though Hyper-V is still pre-1.0 code, I think Microsoft has done a bang-up job with its hypervisor, and it may just turn this Linux freak a Windows 2008 junkie for running his own personal virtualization needs. While VMWare’s ESX is still superior on a number of fronts, including its aforementioned VMotion technology and its more powerful cluster management tools, Microsoft has certainly sent a major warning shot across its bow and the bows of the respective Linux vendors, as well.

More in Review: Microsoft’s Hyper-V puts VMWare and Linux on notice on

InfoWorld’s Randall C. Kennedy, who can never be accused of writing a kind word for Microsoft by any stretch of the imagination, calls Hyper-V a “technically sound, well-performing hypervisor…” in Test Center reveiw: Microsoft’s Hyper-V does the trick.

I’ve been using Hyper-V myself for a while now, and given how easy it is to deploy as a server role in Windows Server 2008, or as a standalone virtualization server using Hyper-V Server 2008, I’m admittedly a big fan and excited about where this train’s headed.

Scott Drummonds’ Video: VMWare FUD?
Back to the VMWare episode— On May 1, 2009, a video titled “Hyper-V Crashes in Consolidated Environments” is posted on YouTube by drummonds1974. The video, which seems to have been updated since then, leads with the following text :

On April 30, 2009, Microsoft TechNet and MSDN went down.
In 2008, Microsoft announced TechNet and MSDN migration to Hyper-V.
Are these two events related?

The video shows some VMs running on Hyper-V crashing, and the mystery voice-over informs you Hyper-V is running a workload “based on VMmark”. VMmark, in case you aren’t already familiar with it, is an “industry-standard” virtualization benchmark— developed by VMWare.

Of course, no technical details about the particular test or the scenario are provided in the video. Towards the end, drummonds1974 quips:

.. in one of our tests, we actually got the parent partition to crash, which brought down the entire server. Here’s a bluescreen of that happening…

You can’t be blamed for thinking “Perhaps a childish prank by a newbie sysadmin who just learnt a new trick or two?”

The final screen of the video boldly concludes: Consolidated workloads crash Hyper-V.

The video was posted by Scott Drummonds, Technical Marketing Manager at VMWare.

Microsoft responds
Jeff Woolsey responded to the video in Hyper-V Winning Daily/VMWare FUD Reaching New Heights. Excerpt:

The poster, who doesn’t appear on the video, doesn’t state what company he works for or provide any context. Gee, I wonder where he works.


On the Hyper-V team, we run thousands of stress tests per week and the stress tests we run are far more invasive than the test in this video. So, I consulted our Hyper-V Supportability Program Manager and dug deeper. I wanted to know if we’ve had any Hyper-V crashes reported. Here’s what I found out.

Of the 750,000 downloads, we’ve had 3 reports of crashes under stress and with the same error code as seen in the video bugcheck (0x00020001). The solution in all three cases was to upgrade the server BIOS which solved the problem. This can happen as hypervisors interact very closely with hardware and BIOS updates generally inlcude updated microcode for processors ofteintimes to address errata.

In case you’re wondering, VMWare has had similar crashes with older BIOSes as well. Here.

Round 2: Drummonds’ non-response
May 15, 2009: (The timestamp can’t be correct, because Woosley’s response to this post is actually dated May 9th… !) Back at VMWare, Scott Drummonds responds with Video on Hyper-V Crashes. Scott states:

..The video and descriptive text have raised more questions than answers.

Now, like me, if you watched the entire video about 5 times in an attempt to get any answers, much as you would appreciate the conciseness of Drummond’s video, it was devoid of any answers. Drummonds continues to bash Hyper-V in his response:

…the run rules were violated to make Hyper-V produce its best results…


09 May 09 09:17: Over on the Virtualization team blog, Woolsey responds with Day Two of the Scott Drummonds VMWare FUD Fiasco. Rather than quote parts of it here, I’ll let you read it and come to your own conclusion.

Of course, it doesn’t end here!

Round 3: VMWare Responds, Again
May 14, 2009: VMWare’s Bruce Herndon responds in Setting the Record Straight on the Hyper-V Video:

I am not exactly pleased to be writing on this particular subject in a public venue…

I can’t help but comment here – Herndon is not exactly pleased about responding, but apparently, posting a public video on
YouTube appears to be perfectly alright.

I had hoped that this whole kerfuffle would quickly die down, but it shows little sign of abating….

You hoped? Wihtout any details forthcoming for two weeks while a colleague from product marketing amateurishly bashes a competitor’s product? As Woolsey points out,

In the meantime, VMware Sales Staff emails customers and would be customers to “check out this video” and VMware senior architects Twitter to “check out this video on You Tube”

Herndon ends his post with:

In the mean time, we intend to focus on helping to build amazing rock-solid products that our competitors can’t yet imagine.

Needless to say, I’m truly amazed by the attitude and tone of VMWare’s posts!

Rather than reproducing Herndon’s post and commenting on every bit, I’ll let you head over to the Virtualization team’s response from 17 May 09 10:01: VMware FUD Fiasco Part 3….

All I can say is— it’s not the VMWare I know, and certainly not the many fine folks who work at its Palo Alto headquarters (I’m super-impressed with their new campus.. every bit as cool as Google’s!). Perhaps the pressure of having real competition to deal with changes things? As Jason Perlow pointed out not too long ago:

Hyper-V represents the first stage of the mass-commodization of hypervisor technology, and if this beta release is any indication, it’s going to be a rough ride ahead for Microsoft’s competitors.

You might ask MSFT how they come up with 750,000 Hyper-V downloads and if using that number is honest… or just more FUD.

Eric, you might ask if you should note that you work for VMware when you post disparaging comments about competitiors?
