Stopping a Virtual PC image from synchronizing the date with your host OS

by James Fielding 3. February 2010 10:53

“What will happen if the date/time on a machine is reset or is in a different time zone?” is a question that we sometimes run into, particularly from professionals whose documents are particularly date/time sensitive. Fortunately, this question can easily be handled by setting up one or more virtual machines.

Having said this, out of the box, Virtual PC virtual machines synchronize their date with the date of the hosting operating system. This means that no matter what control panel you alter in the guest OS, the date/time reverts back to the host OS settings, which can be really frustrating. To prevent this default action from occurring, you can add the following XML section to the .VMC file for the image that you’d like to desynchronize:


<integration>
    <microsoft>
        ....
        <components>
            <host_time_sync>
                <enabled type="boolean">false</enabled>
            </host_time_sync>
        </components>
        ....
    </microsoft>
</integration>

Happy testing,
James Fielding

The right column of the page has an accordion style menu with links to other blogs. Maybe I'll play with the layout to make this a little more apparent.

Thanks,

I have found, in my own experience, that banking on contract testers can be problematic and to a greater extent time consuming IF you want them to work on large-scale consolidation campaigns. Whereas developers lean to come in and work simply on a smaller piece of the endeavour, testers commonly are required to test across functions, systems or business enterprise areas. If you can get in testers to work on lesser parts of the project, thereby permitting your more veteran in-house testers to focus on the cross-domain effort, this could work.

Maybe. It probably depends how professional the company you're outsourcing your testing to is. Reputable outsourcing companies that specialize in testing have tools, methods and resources that most in-house IT departments lack. More importantly, Reputable companies can also have a wealth of experience seeing things go horribly wrong, which can be pure gold for pennies, particularly if your in-house staff miss something. Finally, they should have errors and omissions insurance that should cover off some of your risk.

The bottom line is I'm not disagreeing with you. In-house testing is ideal, particularly if you have a great team with lots of testing experience and resources.

If I had a choice, I wouldn't make this a black & white issue: I'd do both in-house and outsource, too. When it comes to testing mission critical business resources, it is usually worth every penny to have as many eyes-on-the-ball as possible.

Thanks,
James

This blog provides a forum for ScioSoft staff to share their personal experiences on topics that they are working on or find interesting. So the short answer is that we develop the content. Of course, these posts are on technical topics, so we’re obviously not responsible for devising the coding techniques or developing the underlying frameworks that make these topics work.

Sorry, we were just tweaking some things, so it may have made things a little unstable.

Thanks for your understanding,

Nice blog post! Are you using Blog Engine as your main blogging platform? I ask this because your blog looks a little different.

I wouldn't expect comments to be disabled in your comments control panel, as they are enabled by default, but check that setting just to be sure. After that, look for data source configuration issues in your server logs. If you can't resolve the issue, contact me directly using the "Contact" link above, and we'll see what we can do. James
