Jared Payne provides helpful details on the priority values assigned by Fslx.sys to shed some light on the Layer Prioritization section of the SVS White Paper.

One of our readers wrote us that page 9 of the SVS white paper was confusing, with the chart displaying a Base request twice -- for example, with 2 different Default Priorities but no explanation as to why they are different, as follows:

By default, Fslx.sys assigns layers the following priority values:

Rick asked: This product has been in beta for quite a while. Why has it taken so long to release?

Hey Rick, thanks for the question. Hope this answer helps.

  1. The core of our virtualization technology is a file system filter driver. That is a very specialized area -- one of the most advanced concepts in the Microsoft architecture. It must be just right, and we took the time necessary to get it right.
  2. One of our key initiatives in 2005 was to increase customer satisfaction by improving product quality. We completely revamped internal processes, expanded our QA facilities, committed to deploying our own products internally before release, and increased the involvement of customers in the development cycle with longer betas involving more people. SVS is one of the first major releases from Altiris based on this new approach. We have over nine hundred registered beta participants for this...

Greg wrote: You know how when you do many current installations, at the end of the installation there is a checkbox that says "launch application"? Well, if you leave that checked, even though setup.exe, or whatever you used to do the installation, is done, SVS continues capturing system changes because you launched the program at the end. It still sees that as part of the setup.exe thread. Capturing doesn't stop until the application is closed.

You are correct, Greg, and that is by design. A Capture by Process (or "Single Program Capture"), by necessity, must capture the entire process tree -- not just the executable you specify, but also any process called by it as well. That's how we ensure the capture gets everything, since installers often call other embedded or external installers, executables, services, scripts, and even batch files.

By running the application at the end of...

"This all means you can do otherwise impossible things, such as run Microsoft Office 2000 and 2003 on the same PC simultaneously. It also keeps the operating system clean, so badly behaved applications don't conflict with it or each other - the 'DLL hell' familiar to PC support techs - and it allows an application installation to be fully reversed if it causes problems."

Can you please explain the process for installing new software with SVS?

Sure, thanks for the question. Here are the steps:

  1. The Virtual Software Package (VSP) is copied to the target desktop. This can be done using Altiris Software Delivery Solution, another software distribution tool, or through manual methods such as a CD, USB drive, or network connection.
  2. On the client, the archive is extracted to the isolated, hidden section of the file system that is managed by the Filter Driver. At this point, the VSP becomes a file system "layer".
  3. The layer is then activated, which makes it visible to the system and user - everything appears to be in it's normal location, as if the application had been installed conventionally. Activation is nearly instantaneous.

"No messy installation scripts that break under tightened security; no troublesome "artifacts" in the Windows Registry; no leftover files lurking in obscure folders on the local hard disk, waiting to trip up the next deployment. In the software deployment world according to Altiris, applications would materialize and/or dematerialize with the flick of a switch."

A feature in the SVS final release is the ability to configure SVS so certain applications running from the base cannot see virtualized applications. Jared Payne tells us how and when this is cool.

The final release of Software Virtualization Solution (SVS) includes a feature called Program Ignore. Program Ignore makes it possible for applications that are installed in the base to run and not see virtualized data. This feature is quite simple to use.

  1. Open regedit and go to HKLM\System\Altiris\FSL
  2. Create/Edit a new Multi-String Value named "ProgramIgnoreList"
  3. Enter the complete path for the executable that you want to ignore in "ProgramIgnoreList"
  4. Restart the computer (the ignore list is only read at system start up)

Antivirus software is one of the main reasons this feature was added. We recommend adding your antivirus scanner to ProgramIgnoreList. You only need to add the scanner executable to this list. It is important...

Many applications require at least one reboot during their installation. So, how does one successfully virtualize one of these hell-bent-on-rebooting apps? Brian Mann shares some pointers.

If you're trying to install an application into a virtual layer but your application insists on doing an automatic reboot during the installation process, you're in luck.

Unfortunately SVS doesn't handle this very gracefully yet (stay tuned), but here's what you can do to install these apps today.

  1. Start your capture as you would any other.
  2. When prompted, go ahead and reboot. The setup will not continue since the entries that would cause this are in the layer.
  3. Once the system is back up, re-enter capture mode (SVSAdmin, file, update, ...).
    • The easiest way to make sure that all of the correct information is captured by the layer when re-entering capture mode is to re-enter it in a global capture. The only downside is that you may have to do...

Here's a power tip from the tip master, Jeremy Hurren. In this gem, Jeremy shows you a quick way to make it easier to view sublayer information.

If you're a power user who needs to manipulate the information in your layers directly, you may find this useful.

Currently you may be using regedit to look at all the keys under HKLM\SYSTEM\Altiris\FSL to find which two areas match your layer.

Instead, set the following flag in the regsitry key to make SVSAdmin display this for you.

Modify This Key

Flags (DWORD) = 0x00000001

In the details view, you'll get an extra column of data showing "...
