Virtualization Matters Except When It Doesn’t

March 26th, 2012 No comments

In my previous post “Physical is New Virtual,” I mentioned that I would talk about when you will need virtualization and when you don’t. This topic could be a little controversial as we at virtualization community all assume that virtualization is the way to go, which is true in general.

There are however use cases in which virtualization doesn’t make much sense. In the following, I will detail some of these use cases and explain why it doesn’t make much sense to use virtualization. Like everything else, virtualization doesn’t fit all.

Easy Switching RDP and PCoIP Protocol with VMware View

March 23rd, 2012 1 comment

I recently use quite a lot of VMware View because my development environment is a VDI desktop. By default, the PCoIP protocol is used and things just work as expected.

As a power user, I didn’t find PCoIP convenient sometimes, especially when copying files between my physical desktop and my virtual desktop. I ended up using a FTP server instead of drag and drop. It worked but not as quite convenient as I expected it to be.

vSphere APIs for Guest Operating System Management: What’s Special and When to Use It?

March 19th, 2012 13 comments

This is a wrap-up post of recent series on vSphere guest operating system management APIs. If you missed them, here are a few links to related posts: [Note: these are not related to the vSphere Guest API.]

How to Upload File to Guest Operating System on VMware

March 12th, 2012 31 comments

My last post explained how to download file from a guest operating system. Naturally this post is about how to upload file. After a quick sample code, I will discuss how to extend the capability of existing APIs that run program inside guest operating system. My next post will wrap up this series of guest related APIs in vSphere API.

Let’s take a look at a sample code: (To run it, first check out the simple prerequisites in a previous post)

How to Download File from Guest Operating System on VMware

In my last few posts I discussed how to use the Guest Operating System Management API to run program, set/read environment variables. From this post, I will talk about how to move files to and from a Guest Operating System, and advanced features like moving whole directory only implemented in the Guest Operating System Management API.

Set Environment Variables in Guest Operating System on VMware

March 7th, 2012 No comments

While reading my last post on reading environment variables from a guest operating system, you may wonder how to set environment variables. Don’t be disappointed if I tell you that there is NO direct support for setting an environment variable.

However, you have a workaround – use a command directly. Unlike reading variables, there is no standard ways to do it for different operating systems. You have to first figure out what type of operating system and then run different commands. For example, if you are targeting Windows family of operating systems, you simply run the following:

Read Environment Variables in Guest Operating System on VMware

My last post explained how to run, kill, and list programs in guest operating system on VMware. In that post, I mentioned that you can actually use the same API, GuestProgramDirector in particular, to read environment variables. I think the explanation is detailed enough for an implementation.

Still, a good sample provides more details. That is why I decided to write a quick sample just to show how to read environment variables. While trying the sample by myself, I did find more that I will discuss after the sample code.

Run, Kill, and List Programs in Guest Operating System on VMware

In my last article, I announced the Guest Operating System Management API for vSphere. As promised, I will write samples to show how to use the APIs. This post explains the GuestProgramDirector type with an example.

Let’s take a quick look at the following sample:

Having created a sample to run a program in guest operating system using GuestProgramManager, I started to write a similar one to show how to use the GuestFileManager. Compared with the GuestProgramManager, the GuestFileManager is much more complicated to use.

Java Code Style and Formatter

March 2nd, 2012 No comments

While writing samples for my book VMware VI and vSphere SDK, I developed a Java code formatter within Eclipse. Although there are several built-in formatters like Java conventions, Eclipse, and Eclipse 2.1, I still decided to create my own partially due to the special requirements by Prentice Hall, but mostly due to my personal flavor for Java code.

Run Program in Guest Operating System on VMware

Integrating VIX API into vSphere API is a great decision VMware made for its vSphere 5.0 release. Instead of working on two separate APIs, you now have one to deal with. It also solves the portability issue of VIX APIs which is tied to a specific platform – VIX has three versions for Windows, 32-bit Linux, and 64-bit Linux.

VMware Developer Community: Time to Update Contents

February 21st, 2012 No comments

Thanks to John Troyer and VMware community managers, I successfully changed my email for login with the community recently. During this long weekend I spent a little time checking out the developer community.

I found that the static contents out there are largely outdated. In my estimation, it hasn’t been actively maintained for more than one year. Listing outdated contents not only confuses the community, but also lets go a great opportunity to educate and influence developers.

VMware Partner Exchange 2012: Day Three

February 16th, 2012 1 comment

Today is the last day of VMware Partner Exchange 2012. There’s no keynote, therefore I went directly to breakout sessions.
The first one I attended was “SRM 5.0 and vSphere Replication – Understanding the Use Cases and Implementation Options.” The SRM used to manage the storage array that actually replicate LUNs to pair arrays in remote sites. This results in a restriction that the storage arrays must be compatible, which means they must come from same vendor and probably same model. When I was at VMware, I helped several partners with their storage array adapters for SRM. With vSphere replication, the replication happens at higher level thus the restriction goes away. Coming with the flexibility is slightly slower performance. Like anything else, you simply cannot have all the best but you can apply right technology for certain use case, for example, use vSphere replication for ROBO (remote office, branch office) use case.

VMware Partner Exchange 2012: Day Two

February 15th, 2012 2 comments

Same as yesterday, the conference started with keynotes. The first one was by Carl Eschenbach, VMware Co-President of Customer Operations, followed by a motivational keynote by Bill Taylor, founding editor of Fast Company Magazine. As a technical professional, I always try my best to get more business insights and perspectives therefore I attend business related keynotes whenever possible.

VMware Partner Exchange 2012: Day One

February 14th, 2012 No comments

Today is the first day of VMware Partner Exchange 2012 in Las Vegas. As usual, it started with keynotes, presented by Scott Aronson (Senior Vice President, Global Channels and Alliances), Paul Maritz (CEO), and Steve Herrod (CTO & SVP, R&D) consecutively. I personally didn’t find a lot new but mostly rehashed from previous keynotes. Nevertheless, there were several interesting numbers from the three keynotes:

  • $41.5 billion: private cloud opportunity by 2015.
  • 350,000: VMware customer base.

Will Virtualization Really Benefit Environment?

February 13th, 2012 3 comments

Today I read an interesting article “The Efficiency Paradox” in latest Business Week magazine. It reviews the book Conundrum: How Scientific Innovation, Increased Efficiency, and Good Intention Can Make Our Energy and Climate Problem Worse by David Owen. I haven’t read the book but got the main idea of the book from the article.

Chasing Moving Targets

February 8th, 2012 No comments

As John F. Kennedy put it, “everything changes but change itself.” This is particularly true in computer industry where things move faster than other industries. It’s further complicated when you also have dependencies that also move fast.

A good example is that your software project depends on another product which is also under development. Sometimes we call it synchronous development. The payoff could be huge if you can ship your product at the same time as the dependent product which presumably has bigger user base. You can then leverage the go-to market opportunity as first player in the bigger community.

1xN to Nx1: The World Is Flat In Computing

February 6th, 2012 2 comments

The first part of the title of this article may seem like mathematics, but it’s really not. This is just about software packaging – a topic not so often discussed. In plain English, it basically says something like: one application with N features vs. N applications, each of which has one feature. More generally speaking, it can describe software entity with sub-elements. I will discuss it in the contexts of mobile/desktop, and virtual/physical.

Announcing Code Generator For vSphere Java API

February 1st, 2012 12 comments

As I tweeted last week, there would be a big announcement when the open source VI Java API gets 20,000 downloads. It hit target yesterday. To celebrate it, I decide to release the code generator for the API, which William (@lamw) rated as “awesome.”

Management Middleware: The Future of Virtualization and Cloud Marketecture

January 29th, 2012 No comments

While installing and configuring vCloud Director recently, I kept thinking how to simplify it by removing un-necessary concepts and steps. To be fair, vCloud Director as of version 1.5 does a decent job to provide a high level abstraction for cloud infrastructure. Still it can be significantly improved just like every other new technology. Note that I pick vCloud Director as an example for the following discussion simply because VMware is the leader in virtualization space and what it does has ripple effects on other vendors.
