How to create images for argus - a short recipe

In order to work properly, argus needs specialized images, tailored for its needs.

The current document tries to describe what steps are necessary for creating a proper image.

It assumes that the images are created using this repository, instead of the original one,, which I was unable to make it work for our scenarios.

For Microsoft Nano Server there are other stepts, look at the bottom.

  1. First, grab an ISO with the OS you want to create an image for.

  2. You might want to configure Autounattend.xml to suit your needs and to be in a format acceptable for the operating system you’re working with. Make sure to use a proper product key in the <ProductKey> section.

  3. Run sudo ./, which will use the aforementioned Autounattend.xml in order to create an Autounattend.vfd, which will be used as a floppy device later on by another script.

  4. Modify and add the ISO and the qcow2 paths.

  5. Run sudo ./

  6. If the Autounattend.xml was in a format known by the said OS, the installation should be automatic, requiring no manual input. Jump to the glance step. Otherwise, the following steps should be done manually or by customizing the installation scripts.

  7. Install Powershell 3.0 if it’s not installed already. The following document describes how to install it on multiple Windows versions:

  8. Clone somewhere in the created image.

  9. Create the CiAdmin user with the password Passw0rd and make it an Administrator.

  10. Execute Set-ExecutionPolicy Bypass in an Administrator Powershell instance, in order to support running scripts from argus.

  11. Activate RDP support:

    • run SystemPropertiesAdvanced
    • go to the Remote tab
    • Activate Allow remote connections to this computer
  12. Run .\install_git.ps1 from the cloned repository.

  13. Run .\Specialize.ps1 from the cloned repository.

  14. Run .\FirstLogon.ps1 from the cloned repository. Depending on how old your OS is, just doing this won’t be enough. This script will try to detect what virtio drivers are needed, but it might not support installing the latest version of virtio.

    You might take a look at this compatibility table, taken from

OS Numeric Version dir for Storage / Balloon dir for network
W2008 R2 / Windows 7 6.1 Win7 (32/64) Win7 (32/64)
W2008 / Vista 6.0 Wlh (32/64) Vista (32/64)
W2003 5.2 Wnet (32/64) XP (32/64)

In some situations though, just installing these particular versions of virtio will still lead to BSODs when trying to boot the image through openstack and these combinations were found to be useful during our attempts to create new argus images:

OS virtio version for Storage / Ballon virtio version for network
W2008 0.54 0.102 or latest
W8.1 0.102 or latest 0.94
  1. Run .\Logon.ps1. This script will configure WinRM and will finalize the image, by running sysprep.
  2. After the creation script finished preparing the image, you can add it to glance and use its id in argus.conf.

Microsoft Nano Server

1. You need to create a new Nano Server image, you can follow these steps care to specify that you don’t want to install cloudbase-init -AddCloudbaseInit:$false. You need to do this on a Windows host

You also need to create an image for KVM (the script will install the proper VirtIO drivers) -Platform KVM.

  1. Allow ping , SMB and create the CiAdmin User Mount the vhd and create this folder: C:\Windows\Setup\Scripts Add there the PostInstall.ps1 and SetupComplet.cmd that you can find in this repo.
  2. Install Git

You need to download in a windows machine Git for Windows Portable from, install it on that machine.

Copy PortableGit on the same vhd in C:\Program Files\PortableGit.

  1. Now you can upload it using glance.
