Tracking the top issues:

The VMware Knowledge Base

In VMware documentation, we show you how a product works, and how you can use the product to accomplish your tasks. But what about when the product isn’t working for you—when it doesn’t behave as described in the manual, or when the manual doesn’t cover a problem you encounter, or a special task you want to perform? In our procedures we try to anticipate every use case, and in our troubleshooting sections we try to foresee everything that might go wrong, but with the large and growing base of VMware users, it’s impossible to cover every situation that might occur. Every user is unique, and the number of variations—in combinations of hardware, operating systems, and use cases—is practically limitless.

One of the best resources for troubleshooting problems is the VMware Knowledge Base. Maintained by VMware Global Support Services team, the Knowledge Base (KB) contains thousands of articles authored by GSS support techs, product development and QA engineers, and Technical Communications writers. KB articles specialize in corner cases, troubleshooting, workarounds, and more. Thorny, corner-case problems are usually solved only through considerable effort, collaboration, and head pounding by some very smart and knowledgeable people. KB articles document those solutions, so no one should have to struggle with solving the same problems again.

And note: when you search the Knowledge Base, you’re searching not only KB articles, but also the library of product documentation and discussion threads in VMware Communities. This makes the Knowledge Base a great place to begin looking for answers.

So how do you use the Knowledge Base? Just go to http://kb.vmware.com/ and you’ll find that it’s pretty self-explanatory. You can browse or search by keyword, and you can filter the search by product. And if you need more detailed instructions or help, the Knowledge Base itself is well documented (just as you would expect) in a KB article—just click the Knowledge Base Help button in the upper right of the KB home window.

I will add one tip for searching: when I enter search terms, I start by trying to identify as uniquely as I can the symptoms and setup of the problem I’ve encountered—I might include the essential words of an error message, the operating system version of the VM, what seemed to trigger the problem—whatever might help filter the search to the results most likely to match my problem exactly. I err on the side of inclusiveness, using as many relevant keywords as I can. Sometimes, I get lucky and find my problem on the first try. More likely, I get no results, or just a few. So I start deleting terms, one by one, from the search. With every deletion, the search broadens, and I get more results to scan through.

One more note: be sure to take a look at the navigation bar on the right-hand side of the KB home page, where there are links to some other really great tools and services provided by the KB team, including:

  • KBTV, an ongoing series of how-to videos
  • the Weekly KB Digest, where you can check for the newest additions to the Knowledge Base

You can subscribe to KBTV, the Weekly Digest and the KB Blog via RSS, and you can follow us on Twitter at: @VMwarecares.

In short, whenever you need answers, try the Knowledge Base. It’s a terrific resource.

How to setup mirrored folders between your Mac and Fusion VM

Did you know that you can setup mirrored folders for your Mac and Fusion virtual machine?

Mirrored folders allow the Mac and the virtual machine to see the same content in certain personal data folders. For example, any content put on the Mac’s desktop also appears on the Windows desktop. Similarly any content put in the My Documents folder in Windows also appears in the Mac user’s Documents folder.

The mirrored content resides on the Mac so that it is accessible even when the virtual machine is off. Mirrored folders work by redirecting where Windows looks for certain user folders (Desktop, Documents, Music, Pictures, Movies, and Downloads) from their default Windows locations to the corresponding locations on the Mac. It does this by means of registry redirects (much like Group Policy can redirect user folders to a network location). Mirrored folders allows your Windows virtual machine to treat the Mac’s Desktop, Documents, Music, Pictures, Movies, and Downloads folders as its own; it does not, however, let your Mac see the Windows default Desktop, My Documents, My Music, My Pictures, My Movies, or Downloads folders, and your Mac never has access to data saved on the Windows computer.

This video discusses and demonstrates how to setup mirrored folders for your Mac and Fusion virtual machine. For additional information, see VMware Knowledge Base article Setting up mirrored folders for your Mac and virtual machine (1014127).

Take note of those KB articles we present

When filing a Support Request in the My VMware Support Portal, you may notice there is a selection of five KB articles presented underneath the form after you tell us a few things about your issue. These articles are put there to help you resolve your issue before you have even spoken to someone, but did you know there is some intelligence behind what we show you? Today we will explore how we pick these KB articles. It is a rather involved and complicated process, but read on to discover how it’s done.

When you file a Support Request with VMware, everything related to what is done to resolve your issue, is kept as a record. This helps us spot trends, and keep track of issues that may occur frequently. After a certain amount of time, we gather reports to see what common KB articles are used to resolve an issue by the support engineers. The engineers document which KB articles they used in each and every support request they resolve. We then look at the ratings of the article, and how many times it has been linked to. If the KB article maintains a rating above three stars and is linked-to quite frequently, we know that KB article is particularly useful in helping people to resolve that issue. That’s not the only thing we do. We also comb through the case notes of Support Requests to pick up out trends, such as did a virtual machine lock up, did your ESXi host crash, did vCenter Server stop responding, etc.

This is all categorized by different selections our Technical Support Engineers make as they work your support request. We call these vCats which is the problem category, for example Host/Installation, and then a subcategory to describe the issue, a vSubCat, such as a Storage Failure. All this information is trended and tracked. We analyze the data with utilities that can spot these trends automatically although there is a manual component to it. Combing through this data can be a time consuming task. We have ways to automate our reports, but much of the qualitative aspect of analyzing this data is done by perusing spreadsheets, reading comments from the Technical Support Engineers, and the feedback we receive from customers.

Finally, when choosing the KB articles for the My VMware Support Portal we tend to target KB articles that utilize multiple steps and checks to troubleshoot the issue. We call these types of articles Resolution Paths. These step through specific issues step by step, and provide you a process for which to resolve your issue, such as an issue of virtual machine not being able to start up. In this way, it is also revealed how a Technical Support Engineer may troubleshoot the issue.

All in all, the idea is that these KB articles will help you save some time. Hopefully, you find these useful, and think about taking a gander at these KB articles next time an issue arises.
