Building images for Windows¶
We can use New-WindowsOnlineImage
in windows-openstack-imaging-tools
tool as an option to create Windows images (whole disk images) corresponding
boot modes which will support for Windows NIC Teaming. And allow the
utilization of link aggregation when the instance is spawned on hardware
servers (Bare metals).
Requirements:¶
A Microsoft Windows Server Operating System along with
Hyper-V virtualization
enabled,PowerShell
version >=4 supported,Windows Assessment and Deployment Kit
, in shortWindows ADK
.The windows Server compatible drivers.
Working git environment.
Preparation:¶
Download a Windows Server 2012R2/ 2016 installation ISO.
Install Windows Server 2012R2/ 2016 OS on workstation PC along with following feature:
Enable Hyper-V virtualization.
Install PowerShell 4.0.
Install Git environment & import git proxy (if have).
Create new
Path
in Microsoft Windows Server Operating System which support for submodule update viagit submodule update –init
command:- Variable name: Path - Variable value: C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Git\bin
Rename virtual switch name in Windows Server 2012R2/ 2016 in
Virtual Switch Manager
into external.
Implementation:¶
Step 1
: Create folders:C:\<folder_name_1>
where output images will be located,C:\<folder_name_2>
where you need to place the necessary hardware drivers.Step 2
: Copy and extract necessary hardware drivers inC:\<folder_name_2>
.Step 3
: Insert or burn Windows Server 2016 ISO toD:\
.Step 4
: Downloadwindows-openstack-imaging-tools
tools.git clone https://github.com/cloudbase/windows-openstack-imaging-tools.git
Step 5
: Create & running script create-windows-cloud-image.ps1:git submodule update --init Import-Module WinImageBuilder.psm1 $windowsImagePath = "C:\<folder_name_1>\<output_file_name>.qcow2" $VirtIOISOPath = "C:\<folder_name_1>\virtio.iso" $virtIODownloadLink = "https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.133-2/virtio-win.iso" (New-Object System.Net.WebClient).DownloadFile($virtIODownloadLink, $VirtIOISOPath) $wimFilePath = "D:\sources\install.wim" $extraDriversPath = "C:\<folder_name_2>\" $image = (Get-WimFileImagesInfo -WimFilePath $wimFilePath)[1] $switchName = 'external' New-WindowsOnlineImage -WimFilePath $wimFilePath -ImageName $image.ImageName ` -WindowsImagePath $windowsImagePath -Type 'KVM' -ExtraFeatures @() ` -SizeBytes 20GB -CpuCores 2 -Memory 2GB -SwitchName $switchName ` -ProductKey $productKey -DiskLayout 'BIOS' ` -ExtraDriversPath $extraDriversPath ` -InstallUpdates:$false -AdministratorPassword 'Pa$$w0rd' ` -PurgeUpdates:$true -DisableSwap:$true
After executing this command you will get two output files, first one being “C:<folder_name_1><output_file_name>.qcow2”, which is the resulting windows whole disk image and “C:<folder_name_1>virtio.iso”, which is virtio iso contains all the synthetic drivers for the KVM hypervisor.
See example_windows_images for more details and examples.
Note
We can change
SizeBytes
,CpuCores
andMemory
depending on requirements.
