My Virtualization Setup

A couple of months ago, I blogged about the benefits of desktop virtualization. Since then, I’ve received several questions about my configuration and why I chose it. So, I thought I’d share with you the choices I’ve made and why I made them.

The Hardware
Let’s start with the hardware. As a consultant, I need to be mobile. I regularly work at different locations. Whether working from home, visiting a client, or traveling 500 miles per hour in a plane at 30,000 feet. I need to have my work-related stuff at my fingertips.

So, a desktop replacement laptop is my computer of choice. Mine is not necessarily the lightest laptop around and I must admit that when someone near me is sporting a 3 pound mini laptop I occasionally look on with a bit of envy. But, I take comfort in knowing that I have more computational power in my laptop than exists on the Space Shuttle. Plus I get a little exercise when carrying it.

For 10+ years, I’ve used Toshiba laptops. They’ve been rock solid and I’ve never had a hardware related problem with one. The only downside, and it’s significant if you travel, is that they have a horrible battery life. I’ve had a case of the hiccups that lasted longer than my Toshiba laptop battery.

For my current laptop, however, I choose a Dell Inspiron because I could custom configure it rather than having to take a prepackaged configuration from Toshiba. So far, it’s been good. Knock, knock, knock.

It’s nothing fancy. It’s a Dual Core Centrino laptop running at 2.0 GHz. It has 4GB of RAM and a 7200 RPM 160 GB hard disk drive. Certainly not top of the line, but it meets my needs.

My Operating System
For reasons I mentioned in the prior blog posting, I moved into a virtualized environment several years ago while using Windows XP as my operating system of choice.

Once I made that move, I quickly realized that the only activities that remained in my host operating system were email, blogging, writing, and other office related endeavors. All of these could easily be done in most any operating system. So I made the switch to Ubuntu Linux.

Using the LiveCD, the switch as very easy. With a LiveCD, you can boot your computer from the CD or DVD and run the operating system from there without installing anything on your computer, testing it to make sure Ubuntu will work properly with your hardware. If you like it, you can click a button the the desktop to install the operating system on your hard drive. It recognizes your configuration and asks what you’d like to do. For instance, it recognized that I had Windows installed and asked if I wanted to keep that installation and dual boot or replace it. When I chose dual boot, it asked about resizing my partitions to make room for Ubuntu. (It didn’t even mock me for wanting to dual boot.) Overall it was a very nice installation.

I started with dual booting my laptop for a while but over time realized that I didn’t need the Windows partition anymore so I got rid of it. Now I only have Ubuntu on my laptop.

My Virtualization Software
Although there are some open source applications available, I pay to license VMWare’s Workstation for my virtualization. It’s very nice. It allows you to manage your virtual machines and their settings pretty easily. You can clone VMs, take snapshots of them, etc.

I have several VMs that I use for different purposes, include some for development and administration, some for demonstration purposes, some for billing and invoicing, and even one for my iTunes account. Anything that I want to keep isolated for whatever reason, gets its own VM.

Other software applications
But I don’t do everything in Virtual Machines. I use quite a bit of open source software that is very good.

• Office software – I use OpenOffice for my word processing and spreadsheet needs. It’s completely interchangeable with their Microsoft counterparts. For example, when I write magazine articles, I do it in OpenOffice and save them in Microsoft Word format. When I submit them to my editors, they never know the difference. We even send the articles back and forth using the Track Changes feature. It works great for 2003 and earlier formats, but only Ok for 2007 formats. I expect that’ll get better over time.
• Email, calendering, etc – There are number of applications for Linux that are similar to Microsoft Outlook. Evolution, Thunderbird, and others can do most everything that I need, but I’ve opted for a completely online experience using web-based mail, calendaring, and task and contact management. I use Google for the first two, Remember The Milk for task management, and Plaxo for contact management. Having all of that available to me online, regardless of the computer happen to be using is nice. Plus it makes sync’ing with my iPhone unnecessary. It’s all available to me automatically.
• Remote Desktop – Ubuntu comes with a good Remote Desktop software that allows me to RDP into Windows computers and servers.
• Twittering - Adobe Air is available for Linux and I use it to run TweetDeck.
• Text Editing – Emacs is my text editor or choice on either Windows or Linux.
• SQL Client - RazorSQL is a java-based SQL client that works with SQL Server and other RDBMS’.
• Graphics – Gimp, just as powerful a Photoshop, yet free.
• Newsreader – Pan. It’s somewhat similar to Forte Agent, but doesn’t seem to be as powerful or flexible.
• Instant Messaging – Pidgin works with all of the major IM protocols including MSN, Yahoo, etc.
• Music – RhythmBox Music Player. Similar to iTunes.
• Blogging – I’m currently testing ScribeFire, an add-on for Firefox for my blogging client.

Other things that I really like
I use Compiz as my windows manager in Linux. It has great graphics capabilities, including allowing me to view my four workspaces as a cube. If you’re not familiar with the workspaces concept, think of it as 4 different monitors or desktops in the Windows environment. Each is separate. You can open windows or applications in each of the workspaces without cluttering up any one desktop. I typically have email opened in one workspace, a virtual machine in another, TweetDeck in a third, and perhaps a browsers in the fourth.

Some things that I miss
Although there are Open Source equivalents in Linux for most things windows, there are some applications that are just far better in Windows. Some that come to mind are:

• PowerPoint 2007 – It’s simply far better than it’s OpenOffice equivalent.
• LiveWriter – Is probably one of the best blogging clients around.

Using Wine, you can theoretically run programs designed for Windows in Linux. I haven’t tried this myself, but I hear it has mixed results depending on the application itself.

Well there you have it. My virtualized work environment.

Are you virtualized? I’d love to hear about it. And if not, why not?

Cheers!
