Deployment

PowerShell is King – Building a Reference Image Factory

In the world of deployment a reference image is where all begins, basically we take the ISO/WIM from the vendor, install it, tweak it, patch it and on the other side we now a have a customized reference image that is more suitable for our needs. This applies to both clients and servers. There are two ways of doing this, the correct way and the incorrect way. The correct way is repeatable and as automated as possible. This blog is about the correct way and how to automate it just a bit more then usual. You can of coarse modify the script so it will do more, for example upload the images to the correct destination.

Acknowledgement goes to:

What do I need to get this working?

Step 1: Set up Microsoft Deployment Toolkit 2013 on a server

Step 2: Import Operating Systems, applications and create your task sequences

Step 3: Install Windows Server 2012 R2 (or Windows 8.1) with Hyper-V as your “creator”

Step 4: Download the script and enjoy the show

Note:

  • The script is designed to run on the Hyper-V machine, but it is possible to run this remote either using Remote-Sessions or defining –Computer on every Commands that relates to Hyper-V
  • The Solution is tested on Windows Server 2012 R2 with MDT 2013 and ADK 8.1 BUT should work just fine on Windows 8.1

How does the script work?

image

The PowerShell module has a couple of functions

New-AutoGenRefImages

This function will connect to your MDT server, grab the boot ISO, read all TaskSequences from Task Sequences\REF

image

And for each of them build a VM with the same name as the task sequence. When they are all built it will power them on one by one, booting from the ISO and then run the task sequence that corresponds to the name of the the VM. So if you have a TS with the ID of RW81.x86, it will build a VM with that name and run the TS with that ID on that VM.

You might ask your self how that is done?. I’m not using the database, not using GUID number or Mac’s. The main reason is that I want a solution with as little dependencies as possible, so it will work anytime at any customer (almost). Instead I’ loading the drivers for KVP (Key Value Pair Exchange) in WinPE, I grab the name of the VM before the customsettings.ini is read using a userexit script in bootstrap.ini so I have a Property called VMNameAlias wich then is used to control the deployment process, a neat solution IMHO (more on that later)

Remove-AutoGenRefImages

This function will destroy and remove all VMs, it does this by getting all task sequence ID’s from the MDT server, and find corresponding VM’s and then destroy and clean up.

New-RefImage

This is a manual process, you now need to KNOW the Task Sequence ID, since that is a validation in the CMDLET

Remove-RefImage

Also a manual process, it will destroy/delete/cleanup whatever VMname you type in, note that there will be NO questions, it just deletes them, so don’t type in DC01 or something like that.

Get-RefTaskSequence

A simple CMDLET that lists all task sequences that are in the \REF folder in MDT

The Details

Download the Scripts from here: http://sdrv.ms/1hqoJIh

Download devcon.exe from here: http://support.microsoft.com/kb/311272/en-us

Modify ImageFactoryV2.xml

This is my sample XML file and you need to modify it so it will work in your environment.

<Settings>
<DeploymentShare>\\SRVHOST555\MDTBuildLab$</DeploymentShare>
<HyperVHost>SRVHOST555</HyperVHost>
<HyperVHostNetwork>UplinkSwitch</HyperVHostNetwork>
<HyperVStorage>E:\VMs</HyperVStorage>
<HyperVISOFolder>E:\ISO</HyperVISOFolder>
<HardwareProfile>MDT 2010 Profile</HardwareProfile>
<TaskSequenceFolder>MDT:\Task Sequences\REF</TaskSequenceFolder>
<StartUpRAM>2</StartUpRAM>
<VLANID>0</VLANID>
<VHDSize>60</VHDSize>
</Settings>

Modify bootstrap.ini

Bootstrap.ini needs some modification (besides being silent). You need to add the following:

image

In text:

[Settings]
Priority=Default

[Default]
DeployRoot=\\SRVHOST555\MDTBuildLab$
UserDomain=NETWORK
UserID=Administrator
UserPassword=Password02
SkipBDDWelcome=YES
SubSection=ISVM-%IsVM%

[ISVM-True]
UserExit=LoadKVPInWinPE.vbs

This will load a userexit script that installs the driver for KVP and create a fake services that will allow it to load.

Modify customsettings.ini

You need to modify customsettings.ini so it will read in the values from the KVP correctly

image

In text:

[Settings]
Priority=Init,Default
Properties=VMNameAlias

[Init]
UserExit=ReadKVPData.vbs
VMNameAlias=#SetVMNameAlias()#

[Default]
TaskSequenceID=%VMNameAlias%

You need to add the Property VMNameAlias under the Settings Section

You need to create a new Section called Init that runs the UserExit

You need to set the TaskSequenceID to match the returned value from the UserExit script

Modify the boot image:

You need to make sure that those two scripts are added correctly and we also need the driver for KVP. One easy way is to use the “Extra” folder feature in MDT, whatever you put in that folder will end up on the boot image.

My deployment share is located in

E:\MDTBuildLab

so I created a folder called

E:\MDTBuildLab\Extra

In that Folder I two folders, Deploy and KVP. In the folder Deploy I have a subfolder called Scripts.

Like this:

image

Content of the KVP folder:

In the KVP folder you need to add the driver for KVP, and that you can do by searching for VMGuest.iso on your Hyper-V host, it is in C:\Windows\System32, mount that is and extract the drivers.

The driver you need is in the support\x86\Windows6.x-HyperVIntegrationServices-x86.cab and the folder is namned x86_wvmic.inf_31bf3856ad364e35_6.3.9600.16385_none_968283a5680527fe

(read Keith Garners blog for details, Note: In Keith’s blog it is 64 bit, I’m using the 32 bit driver, since I boot from the x86 boot image. Therefore the name is different of course.)

You also need to store devcon.exe in that folder

When you got them, it should look like this in the folder

image

Content of the Deploy\Scripts folder

In this folder you store the LoadKVPinWinPE.vbs script

Like this:

image

Update the BootImage:

In the Boot Image setting for WinPE, for the setting called Extra directory to add, browse to your folder, apply, update boot image.

image

The Scripts:

LoadKVPInWinPE.vbs

Mainly “borrowed” from Keith’s blog, just modified to use devcon.exe instead the method suggested by Keith

    • Yes, it will basically work. The difference is what version of WinPE you are using, diffreant versions are handled differently when it comes to loading the integration components. If possible I would recommend an upgrade to MST2013 if possible (MDT 2013 “needs” ADK for Win 8.1 to work correctly)

  1. Hey Heard you talking about this at TechEd and was really impressed with it, but I am having a heck of a time trying to get it work. Are you offering any sort of assistance with it?

  2. Great guide…. put everything into a build with Server 2012 R2 running hyper v.

    Running into a small issue… while MDT is processing the [default] rules (see the devcon window run twice) and then the whole vm resets and starts over. Any ideas what could be causing that?

    • Devcon runs once, but it then runs an other process, so you should see 2 windows. The most common reason for that is that it cannot find the Tasksequence. The easy fix is to see if the wizard is picking up the correct info. Set the SkipTaskSequenceID=No in customsettings.ini, that way the wizard stops and you can see if it has selected the correct TS. If not there is a problem with the integration components not setting the VMAlias to the name the TaskSequence have.

      • Thanks — i changed the setting and im not even getting that far.

        Would it make a difference if i am using ‘Windows 8.1 ADK Update’ versus just the ‘8.1 ADK’?

      • Not sure, since don’t use the update (there is only one reason to use it and that is WIMboot, other then that it is not recommended to use that version) But that could be the reason. The problem in that case would be that it does not load the Integration Services or that the fake service can not start.

  3. Well after a lot of troubleshooting, I narrowed it down to something between the vm itself and hyper-v. After the devcon commands run for some reason the VM then resets itself:
    ” was reset by the guest operating system. So I am a little perplexed.

  4. Update #2 — got it working!!!!!!

    The pesky ‘/r’ on the devcon command is what was prompting the vm to restart itself over and over. Once I removed that the process works flawlessly.

  5. From a hyper-v host that is domain-joined, is there any way to to connect using the MDT provider to an MDT server that is in a Workgroup? The MDT provider does not support the use of credentials. If I’m on the same domain, this tool works flawlessly. Thank you very much!

  6. I know i must be dim, but: Where is the user Administrator created? It’s not a domain user? Created locally on the box where MDT is running?

  7. Stupid question but got to ask: The user Administrator which is used in CustomSettings, is it created on the box that runs MDT?

  8. Hi Mikael, Question for you. Using the Imaging Factory, notice that one of my reference images eats the entire Space on the HD when building. I am not sure if its hyper-V doing it or if its the OS itself, but all of the space is gone on the drive. Ideas?

  9. Hi Mikael-
    Would this process work for building a Windows 2008R2 reference image?

    Thanks!

    Zack

  10. Hi Mikael.
    Could not get this to work with a X64 WinPE 10 image. I tried to use the Windows6.x-HyperVIntegrationServices-x64.cab drivers from Windows 8.1 X64. So it looks like WinPE 10 X64 does not play well. (maybe I did something wrong…) I got the following error in WinPE: “The subsystem needed to support the image type is not present”

    Worked as charm on WinPE 10 X86 with the drivers from Windows 8.1 so it really does not matter, but I thought you would like to know….

    I love the post and I love the scripts! Great work.

    • I also had issues with x64 bit, but it does not matter when you do a ref image, since you are using Gen 1 BIOS based machines, it works anyway. Thanks for testing the new drivers btw, also, there is a new version of this coming up, one set of functions for the ref image factory using SCVMM and abetter version for Hyper-V

      • Good to know that I am not the only one that issue with X64. :-) Really looking forward to the new version. Will the new version have multithreading? It would be cool if it was possible to specify a maximum number of threads in the XML so that the script could start up multiple VMs at the same time. I tried to implement this in your script yesterday, but I was unsuccessfull. I tried to use workflow object in Powershell to achieve this. Seems that it is difficult to have a wait inside the workflow.

      • For the Image Factory that works against SCVMM it works that way and since everything is based on separate functions you can control/modify it anyway you want it :-)

  11. Hi Mikael,
    My lab is stuck in “Processing bootstrap settings. Processing rule: Default”. When I remove the bootstrap post “UserExit=LoadKVPInWinPE.vbs” the TS will start. Any ide of what could be wrong?
    Best regards
    Magnus

  12. Hi Mikael,

    I am trying to run this on Windows 10 with MDT 2013 update 2. When booting off the ISO it hang’s on Processing rule: DEFAULT, It appears to be not running an exitscript.when looking at the BDD.log.

      • Thanks, just got that part working my problem was using devcon from WDK 10, was the x64 bit version trying to use the x86 boot image.

  13. Thanks For posting this.
    For me, it’s Building the Virtual machine, booting the ISO, but stops and lists the 3 Task Sequences in the REF folder, it doesn’t start the one it’s assigned (Matching the Task Sequence ID) . Any idea what setting I need to tweak to kick off the Task Sequence?

    • Gary, which setting was it you needed to modify? We are seeing the same issue. The image process stops at the Task Sequence selection screen instead of automatically selecting the correct one and proceeding to apply.

  14. Hey Mike, Do I need to modify anything in the main PS script if I am only using x64 Boot Media to create my ref Images? What is this about?

    $ISO = $MDTSettings.’Boot.x86.LiteTouchISOName’

    • In theory, yes, “but”, there is no value using a x64 boot image anyway, you should create the ref image on a BIOS based machine, not UEFI. Since BIOS based VM’s does support cross-boot there is no need and no benefit. You also need to have x64 based drivers for WinPE and you also need a devcon.exe that works in X64. So, short story, stick with x85 for boot, that works, no issues and it is plain and simple, it also supports x86 and x64.

  15. Hey Mikael,

    when is the multithreaded version going to be released? The one you mentioned above “For the Image Factory that works against SCVMM…”.

  16. In reading Michael Niehaus’ post on the “Image Factory” he has an option to select MaximumRunning VMs at a time. Is there a reason you did not include that in your solution? We are building reference images for all Microsoft supported OS and all languages so doing 300+ images in a serial fashion would take forever. I just wanted to understand if there was a technical reason not to have several VMs running at the same time if the HyperV system has the resources available to it.

  17. I’ve been unsuccessful in setting this up in my lab for the past two days. Can you please offer some assistance. I apologize for the length of this comment… but oh well here I go.

    My Hyper-V host is a Windows 10 Enterprise machine
    My Hyper-V guest/Task sequence is Windows 10

    • devcon.exe

    My DevCon.exe was obtained from “C:\Program Files (x86)\Windows Kits\10\Tools\x86\devcon.exe”
    Likewise LoadKVPInWinPE.vbs was copied to
    D:\ONEDRIVE\OSDEV\DeploymentShare\Extra\Deploy\Scripts\LoadKVPInWinPE.vbs

    I updated my boot disk
    Ran the following from elevated Powershell prompt
    D:\ONEDRIVE\OSDEV\DeploymentShare\ImageFactoryV2Scripts> Import-Module .\ImageFactoryV2.psm1
    D:\ONEDRIVE\OSDEV\DeploymentShare\ImageFactoryV2Scripts> New-AutoGenRefImages

    The VM successfully was generated and booted with the x86 ISO
    I then receive two Devcon.exe’s and a VM restart, with no task sequence run

    If I set SkipTaskSequenceID=No in customsettings.ini the task sequence that matches the VM name is not automatically selected
    If I open a command prompt via F8 and manually load the integration components using the same command below that I find in the “LoadKVPInWinPE.vbs” thusly

    X:\KVP\devcon.exe install \KVP\wvmic.inf vmbus\{242ff919-07db-4180-9c2e-b86cb68c8c55}

    The command runs and reports “…Drivers installed successfully”
    I believe this indicates that I have the correct compatible integration components in my boot disk
    Note: I removed the “/r” to prevent restarts, this might have been a mistake

    X:\MININT\SMSOSD\OSDLOGS\BDD.log has the following entries

    UserExit: started…
    User exit \\\DeploymentShare\Scripts\ReadKVPData.vbs called successfully, skip = False

    …UserExit: Running function SetVMNameAlias…

    Thank you in advance

  18. At ignite this year I noticed that you were using an ImageFactoryv3 powershell script. Are there many changes between version 2 and version 3? I did not see v3 on your onedrive share.

  19. Hey Mikael,

    I’ve pretty much followed every step as far as preparation and still having issues executing. Was wondering if you could offer any assistance. Essentially generating an error when trying to execute New-AutoGenRefImages function of “Unable to Find ISO, exit” and I can confirm the iso to boot to the MDT is located there.
