VDI on VMware Virtual Infrastructure: Using the three main components

In some aspects, Virtual Desktop Infrastructure (VDI)
takes the best of server-based computing and removes many of the
drawbacks. Most people understand that the concept of VDI is using
virtualization software, typically VMware Virtual Infrastructure 3
(VI3), to host instances of a desktop operating system instead of a
server operating system…

Configuring VLANs in VMware VI3 (Virtual Infrastructure 3)

The key to understanding VI3’s support for VLANs lies
with the concept of a “VLAN trunk”. A non-trunk port—also called access
port—carries traffic for a single VLAN, but a trunk port carries
traffic for multiple VLANs simultaneously…

Authentication in a VMware VI3 Implementation

Many organizations that have implemented VMware Virtual
Infrastructure 3 (VI3), including both ESX Server and VirtualCenter,
but do not have a firm grasp of how these components handle

New York Times: licensing, OS lock-in, and, yes, competition

From the Saturday, February 24, 2007 edition of the New York Times, A Software Maker Goes Up Against Microsoft. As the title implies, the story hook is competition between VMware and Microsoft. But the real issues are how customers are affected by hypervisor lock-in and licensing limits.

In a meeting with corporate customers in New York last month, Steven A. Ballmer,
Microsoft’s chief executive, said, “Everybody in the operating system
business wants to be the guy on the bottom,” the software that controls
the hardware. … When quizzed on
Microsoft’s plans, Mr. Ballmer replied, “Our view is that
virtualization is something that should be built into the operating
system.” …

VMware, however,
points to license changes on Microsoft software that it says limit the
ability to move virtual-machine software around data centers to
automate the management of computing work. A white paper detailing
VMware’s concerns will be posted Monday on its Web site (www.vmware.com), the company said.

“Microsoft is looking for any way it can to gain the upper hand,” said Diane Greene, the president of VMware.

The white paper will be available next week, but in the meantime, if you need to catch up, go check out our blog entries from last November, Freedom from OS lock-in.

Given the subject of the New York Times article, it must of course quickly bring up the ghost of Netscape. The article explains virtualization, the benefits of server consolidation, and gives the basic history of the company and the upcoming IPO. The real issues are touched on lightly — the article explains well the relationship of virtualization and the OS (inside or underneath?), and it mentions that VMware thinks licensing changes will affect customers and prevent many people from fully utilizing their virtual infrastructure. The article ends back on competition.

Virtual Iron and XenSource take opposing views on Microsoft’s recent
moves. “Microsoft sees VMware coming between them and their customers,”
said John Thibault, president of Virtual Iron. “So Microsoft is
manipulating its license terms to see if it can freeze the market and
slow down the trend.” …

VMware, according to Microsoft,
should see the wisdom of the path XenSource chose. In his meeting with
corporate customers recently, Mr. Ballmer sketched out a future in
which Microsoft would put fundamental virtual-machine software in its
operating systems, and “VMware builds on top.”

VMware is leery of
such an accommodation, fearing it would prove to be a one-sided
bargain. “We will not sign agreements that give Microsoft control of
this layer,” Ms. Greene said.

See you Monday for more on the issues.

This apple makes terrible orange juice!

There’s nothing more likely to get a VMwarite riled up than comparing Microsoft Virtual Server (MSVS) and VMware ESX Server. Although they both virtualize an x86 system, MSVS runs on top of Windows, and ESX Server doesn’t. VMware does have a server product that runs on top of a host operating system like MSVS, and it’s the free VMware Server. MSVS should by all rights be compared to VMware Server, not ESX Server. ESX Server is much more powerful, but comes at a higher price, a bit more complexity for enterprise-scale deployments, and a smaller universe of supported hardware.

So let’s look at this article by the usually excellent Alex Barrett at the usually excellent SearchServerVirtualization. It starts with a fair premise — for some small shops, it’s a path of least resistance to just use MSVS and call it a day. And when you read closely, Alex mentions VMware Server, but when the people he interviews start talking about price and VMotion in an article on MSVS, my alarm bells go off.

Microsoft Virtual Server flawed, not broken, users say.

That’s fairly typical of most small shops, said Chris Wolf, senior analyst with the Burton Group and author of Virtualization: From the Desktop to the Enterprise. "If [you] have just a few test systems, you’re not going to see much of a difference in performance," he said, between MSVS and VMware. But systems that start to max out their physical RAM might not get the performance from MSVS that they would with VMware, whose memory management feature moves underutilized memory to the hard disk, freeing up RAM for other busy virtual machines.

I think he’s talking about ESX Server’s balloon memory driver, which along with shared memory pages does help use memory more effectively between multiple virtual machines … for ESX Server, not VMware Server. Also note how he compares "MSVS" (a product) and "VMware" (a company name, but he means ESX Server).

But the performance kick he gets from VMware does come at a price:
having to learn an unfamiliar new operating system. "I wish I were more
of a Linux person," Laudenslager said about having to administer his
Linux-based VMware Server. Especially when it comes to setting up
security policies, "I feel I could do a better job with Windows."

Laudenslager should be running VMware Server on Windows, not Linux, if he’s a Windows person. VMware Server comes in both flavors.

Then, there are a few things that MSVS flat out does better than
VMware. Hardware compatibility, for one thing, said Anil Desai, an
independent consultant in Austin, Texas. VMware has done a good job
expanding an extensive hardware compatibility list, but it can’t
compare with the 20,000 to 30,000 devices supported by MSVS’s
underlying Windows Server 2003 platform, Desai said.

Again, if you run VMware Server on Windows, you get to take advantage of all the device compatibility of Windows 2003, the same as MSVS does. It’s when you move up to the power of ESX Server that you start having to be more careful about hardware compatibility.

If you buy contemporary hardware from tier-one OEMs, hardware
compatibility shouldn’t be much of an issue for most VMware shops, said
Andrew Kutz, an operating systems specialist for the University of
Texas, which runs VMware. But, "if you’re a white box shop that builds
all your own stuff, you’re going to run in to some problems," he said.

And now I sound like a broken record — use VMware Server on Linux or Windows on your white box all day long. Go to the VMware Forums if you’re hardware savvy and you can probably even get ESX Server up on unsupported hardware for your lab, although we don’t recommend it for production. But great googly moogly, don’t go saying VMware doesn’t have a free product to run on that cheapo white box you just bought — just use VMware Server!

Is it sour grapes to complain about an article that calls your competitor’s product "flawed" in the title? I see this mistaken comparison so often, maybe I should start a new "apples to oranges" category in the blog for all these sightings. Of course, they’ll go away as soon as Microsoft’s upcoming Viridian hypervisor is here (2008? 2009? Infinity + 1?), and they strangle MSVS and dump it in a back alley. In the meantime, I guess VMware has some more marketing to do, since VMware Server is a great solution to pop on top of Windows Server and get started virtualizing — no cost, no  Linux, and it runs just fine on your current hardware.
