Remaindered Links for October 20, 2008

Why I love ESXi – EMC’s Chad Sakac will be joining us on the podcast on Nov 5.

I poked, prodded.  I tore my hair out.   I was stuck with no
bootable controller/drive combo, and was considering a trip to Fry’s
for another MB whose SATA controller I would know would work (an older
nvidia MB for example).

Then, I had an idea. 

When does your “free” Hyper-V Server cost $1304? – new blog VCritical from VMware’s Eric Gray. (Eric asked me for feedback – Eric, the blog is great so far, just keep telling us what you think.)

If you read through that blog post you will discover that for every
hypervisor managed by SCVMM you will owe Microsoft $1304.  Or, you can
opt to pay $1497 and also use the other System Center features.

Just remember this when you hear the “free, free, free” and the “management, management, management” rhetoric:

It’s actually one or the other, not both.

7 tips for succeeding with virtualization – Denise Dubie @ Network World via Mike D.

"Enterprise IT managers are going to have to start thinking virtual first and learn how to make the case for virtualization
across IT disciplines," says James Staten, principal analyst at Forrester Research. "This will demand they change processes. Technologies can help, but if managers don’t update their best practices to handle virtual environments, nothing will get easier.

IDC: Microsoft Grabs Market Share from VMware – Mike says take a deep breath and look at the numbers. Don’t believe everything you read.

Microsoft bloggers, general bloggers, and press – make sure you realize
that the sky is not falling with VMware market share. The methodology
used in this report is questionable at best and does not reflect the
total market share, revenue, or shipments from VMware.

Virtualization and Compliance – from VMware’s Charu Chaubal. Two takeaways: 1. You should be checking out VI:OPS, because it’s starting to get very interesting to those of us running a data center. 2. You should check out the new Compliance Center over on the main site as well.

To help answer the question, "how can I achieve compliance in my virtualized environment", we recently launched the VMware Compliance Center.
We have provided some overview information, a list of partner solutions
that can help with achieving, maintaining, and demonstrating
compliance, and a list of resources, including whitepapers, webcasts,
and podcasts from leading vendors in this area.

Is Microsoft Exchange 2007 Supported on VMware? another one from Mike. See also how VMware is the best platform for Exchange.

The short answer is yes.

Some Guiding Principles for Chargeback with Server Virtualization (Part 1) from VMware’s Gerod Carfantan. He doesn’t believe these are "best practices," but they’re still worth reading:

Many chargeback models are focused simply on cost recovery. This is a
missed opportunity, and it diverges from the way products are priced in
the "real world". Companies that sell goods and services of all sorts
set their pricing not only to recover costs and make a decent profit,
but they also have pricing strategies that attempt to affect the
behavior of customers, partners, and competitors.

http://cloudcomputing.alltop.com/ – Planet V12n denizens Tarry Singh and virtualization.com are right there along with about three dozen others.

ZEN and the Art of VMware ESX Storage VMotion (or ‘A Quick Guide to Storage VMotion’). is a good overview from Kiwi Si via DABCC. Also check out some future version of the GUI in this demo:

From VMware:

  • VMware’s addendum to our white paper "Microsoft Virtualization Licensing and Distribution Terms" (some good new developments, a few clarifications, and a few more data points)
  • VMworld 2007 registration now open
  • You have tried the TCO Calculator, yes?
  • Workstation 6.0
    • virtualization.info: Feature comparison: Workstation 6.0 vs Server 1.0
    • Adrian Kingsley-Hughes at ZDNet: "I have a philosophy when it comes to new versions of software that I
      use a lot.  What I like to see is a new product that’s familiar enough
      so I can get on and use it without having to dive into the manual too
      much, but at the same time I like to see a crop of new, useful
      features.  VMware Workstation 6 delivers on both of these expectations."

VI3 — A 90 Day’s Review from Andy Murrey

Well,
I have been running VI3 for a little over three months. So
far I would l have to say that I am very impressed with the new
functionality included in this release from the ESX Server side of the
house. I am however, not so impressed with Virtual Center 2.01. It has
a lot of potential, but leaves a frustrating user experience behind. …

What
really makes this software great for me is the community that supports
it. Usually you would see this type of support for an open source
application, and few of them if any. VMWare has done a great job in
rewarding its community and maintaining a superb VMTN site. [Thanks! -JT]

Mark Cuban (yes, that Mark Cuban) on the future of personal computing (VM’s on your gaming console)

Michael Parekh on IT: On Microsoft and Apple vs VMware and Parallels

With increasingly powerful hardware available at more affordable
prices every day, virtualization then allows me to pick and choose the
OS and/or JUST the OS feature I wish to run in order to,

  • run specific computer applications and/or web applications that I can’t run on another OS,
  • access certain peripherals that I can’t use on another OS using the same hardware,
  • get certain OS features that are not available on another OS. …

Having the OS company try and offer virtualization as a "feature" is
fairly contradictory and self-serving from the ultimate user/customer’s
perspective in the long-term.

rPath’s Billy Marshall on OS licensing in a world of dynamic virtual appliances:

For example, a payroll application might run for a couple of days every
month, but otherwise, it is not needed. With software appliances, the
payroll software appliance would be deployed to a computer (atop the
hypervisor) to run during the days before payday, and then be removed
from the machine to make room for other applications to run more
speedily during the rest of the month. Should the customer pay for a
“full time” license to the operating system that is inside the payroll
software appliance? Or should they have a “part time” license that more
closely reflects the manner in which they use the payroll software
appliance?

Spanning the globe: more remaindered links

If you’re not watching Planet V12n, you’re missing out. It may seem like a firehose, but it’s really is the best of the web on virtualization, both the industry and best practices in the field. Often we won’t cover the same topics here on VMTN Blog because I assume you are also checking Planet V12n. It has a news feed if you are so inclined, so no excuses.

Some highlights from this week from the practical tips category:

And since we’re in the practical category, here’s some of my more practical Remaindered Links from the last two weeks:

Remaindered Links – Dec 15

virtualization.info:

VMblog:

Virtualization Daily dissects the spin on a this article: "They seem to be wanting to make this controversial which is a little odd."

Server consolidation: Marcus Wynwood says all the cool kids are doing it:

Think about it, why would you want to look after a rack full of
servers, each with their own OS (that you need to maintain), each with
their own spaghetti cable and one big KVM
to switch between them when you really only need to look after one or
two servers? Instead of having lots of little servers, get your hands
on a fast machine with lots of RAM and a big hard drive, and start consolidating your servers with virtualisation.

Todd Biske via Joe McKendrick via Ipedo’s Integration Insider:

With SOA and Web services, "it’s entirely possibly to have dramatic
changes in load from when the Web Service is first deployed. As a new
consumer comes on board, the load on the service can increase by tens
of thousands of requests per day or more very easily. Furthermore, the
usage patterns may be vary widely. One consumer may use the service
every day, another consumer may use it once a month, but hammer it that
day. All this poses a challenge for the operational staff to ensure the
right amount of resources are available at the right time. The ease of
virtualization can allow this to happen."

Transforming Hyperic – What Developers Gain from Virtualizaton

While its true that most virtualization packages these days come with
management utilities, most of these are really bent around lifecycle
management – which includes provisioning, appliance construction,
backup, P2V conversion and monitoring of the hypervisor itself. What’s
ignored is the systems management inside the little black boxes that
get provisioned. These systems have unique applications and services
that are consuming resources. While the hypervisor does a good job in
general of providing CPU and disk resources based on your rules, it
does not facilitate really understanding the performance of those
applications and services operating in the made-up reality of a
virtualized host. The management problem is compounded by the ease of
which new virtualized systems can be rolled out along with the
flexibility of virtual hardware. Not only does this management get
harder, it changes more often.

Remaindered Links – Dec 9, 2006

Stuck inside this weekend? Here are some links for your virtual reading pleasure:

Geert Baeke at baeke.info:

Sun’s Lou Springer at Inchoate Curmudgeon should be on your reading list :

Mark Wilson asks:

Ever since Microsoft announced its new licensing policy for virtualisation,
I’ve been trying to get an answer on whether the "4 free guests with
every copy of Windows Server 2003 R2 Enterprise Edition (or unlimited
guests with DataCenter Edition)" applies when non-Microsoft
virtualisation products are in use.

And gets an answer from Microsoft’s FAQ on virtualisation

"Licensing
does not depend on which virtualization technology is used. With a
license for Windows Server 2003 R2, Enterprise Edition, you can run one
instance of the software in a physical operating system environment and
up to four instances in virtual operating system environments. With
VMWare GSX Server, this means you can run one physical instance plus
four virtual instances. With VMWare ESX Server, it means you can run
four virtual instances because there is no need for a physical
instance."

(He
also wonders why VMware hasn’t clarified its licensing for 8-core
processors. But man, the quad cores are just coming out, so announcing
anything about 8 cores seem premature, doesn’t it?)

A bunch of Security Matters: Virtual Machine detection

Nowadays, more than 50% of the malware that we analyze has some kind of
virtual machine detection in its code (typically the SIDT method), and
if they detect any virtual machine, they just do nothing. So, perhaps
that’s a good idea for our production servers, migrating them to
virtual software and in any case they got compromised, the malware code
won’t run on them.

murphee’s rant: Virtual Build Appliances

Let me be clear about this: this is the way that software will be
distributed. Virtualization solutions like this (be it VMWare or Xen)
will allow us to leave the current mess of software dependencies
behind. No worrying about target Operating systems, their versions,
their current state of configuration, or (for Windows machines) their
current system rot status. Nope, just setup everything you need in a
system, preconfigure it, and when you‘re ready to ship: freeze it. The
user simply takes your images, points his VMWare or Xen at it and …
well… that‘s it. Throw in solutions like Qemu, and you don‘t even have
to care what CPU your user is running.

A Day in the Life: Singing the Same Old Song (go read the whole blog; warning: strong language and very funny: make sure your drink doesn’t spurt out all over your keyboard)

But what about operating system base images? That’s where it gets
tricky. Only the admins have access to set VMWare to point the "CD
drive" to an ISO image in order to install a new OS. Rusty knows not of
Red Hat or SuSE and with gentle prodding can be convinced to accept a
new, latest-and-greatest ISO from ftp.novell.com, but he does know
Windows. He knows that Vista is beta and that we don’t support beta.
