Windows Server 2008 R2
Hyper-V Server 2008 R2
Windows 7
Windows Server 2012
Hyper-V Server 2012
Windows 8

Hyper-V Server 2012 R2
Windows 8.1

Supports both x64 and x86 images.

How to create a Windows template image

Requirements:

A host or VM running Windows
Clone this repository and unblock its files (this is really important, otherwise the generated image won't work!): https://technet.microsoft.com/en-us/library/hh849924.aspx
A Windows installation ISO or DVD, that needs to be either mounted or extracted (e.g. with 7-zip)
For KVM, download the VirtIO tools ISO, e.g. from: http://alt.fedoraproject.org/pub/alt/virtio-win/stable/

Example PowerShell script:

Import-Module .\WinImageBuilder.psm1

# The disk format can be: VHD, VHDX, QCow2, VMDK or RAW
$virtualDiskPath = "c:\Images\mywindowsimage.qcow2"
# This is the content of your Windows ISO
$wimFilePath = "D:\sources\install.wim"
# Optionally, if you target KVM
$virtIOISOPath = "C:\ISO\virtio-win-0.1-81.iso"

# Check what images are supported in this Windows ISO
$images = Get-WimFileImagesInfo -WimFilePath $wimFilePath
# Select the first one
$image = $images[0]
$image

# The product key is optional
#$productKey = "xxxxx-xxxxx"

# Add -InstallUpdates for the Windows updates (it takes longer and requires
# more space but it's highly recommended)
New-WindowsCloudImage -WimFilePath $wimFilePath -ImageName $image.ImageName `
-VirtualDiskFormat QCow2 -VirtualDiskPath $virtualDiskPath `
-SizeBytes 16GB -ProductKey $productKey -VirtIOISOPath $virtIOISOPath

No extra configurations are needed for specific Windows versions, the New-WindowsCloudImage cmdlet takes care of everything.

How to upload the image in OpenStack

We're not yet done, the next steps consist in:

uploading the image to Glance
booting an instance on your target hypervisor compute node
waiting for the setup to complete (the instance will shutdown once the setup is done)
take a snapshot of the instance which will contain the final sysprepped image ready for your deployments

TODO: Add OpenStack scripts

Notes

The Windows host where you plan to create the instance needs either:

A version greater or equal to the version of the Windows image that you want to generate
A recent Windows ADK installed

E.g. to generate a Windows Server 2012 R2 image, you need a host running either Windows Server 2012 R2 / Hyper-V Server 2012 R2 or Windows 8.1.
