Preparing a Windows OS image to create a VM

The Windows Server 2016 CORE edition image is used as an example, the commands are given in PowerShell.

1. Make sure that you have installed and configured Git.

2. Clone a repository with automated build scripts windows-imaging-tools.

3. Clone the repository to update the system image WindowsUpdateCLI.

4. Set up the toolkit:

   • Install the drivers VirtIO (KVM).
   • Configure Hyper-V in a way that is suitable for you (example), if this has not been done before.
   • Download and install Windows ADK.

5. Download the ISO image of the operating system for which you plan to migrate to VK Cloud. It is recommended to use the en-US version of the image.

6. Make sure that OpenStack client is installed and authenticate to the project.

1. Connect the downloaded OS ISO image.

2. Output a list of all Windows versions using the command executed on behalf of the administrator:

   Copy
   Get-WindowsImage -ImagePath E:\sources\Install.wim

   Here E:\sources\Install.wim — full access to the system's WIM file on the mounted disk.

   A list of editions will appear indicating the ImageIndex of its number:

   Copy
   ImageIndex      : 1ImageName       : Windows Server 2016 StandardImageDescription: This is the recommended option. It reduces management and maintenance by installing only what is required for most applications and server roles. It does not include a graphical user interface, but you can fully manage the server locally or remotely using Windows PowerShell or other tools. See the section "Windows Server Installation Options".ImageSize       : 9 146 079 566 bytesImageIndex      : 2ImageName       : Windows Server 2016 Standard (desktop features)ImageDescription: This option is suitable if you need a graphical user interface (for example, to ensure backward compatibility of an application that cannot work when installing the main server components). All server roles and components are supported. More detailed: "Windows Server Installation Options".ImageSize       : 15 219 002 744 bytes

3. Export the revision with ImageIndex = 1 using the command:

   Copy
   dism `/export-image `/SourceImageFile:E:\sources\Install.wim `/SourceIndex:1 `/DestinationImageFile:D:\Temp\install.wim `/Compress:max `/CheckIntegrity

   Here:

   • D:\Temp\install.wim — the full path on the local disk where the exported image will be saved;
   • SourceIndex:1 — index number of the required revision.

Create virtual switch external with an Internet connection.

1. Go to the windows-imaging-tools directory and import the modules:

   Copy
   pushd windows-openstack-imaging-toolsImport-Module .\WinImageBuilder.psm1Import-Module .\Config.psm1Import-Module .\UnattendResources\ini.psm1

2. Transfer the contents of the directory WindowsUpdateCLI to windows-openstack-imaging-tools\UnattendResources\WindowsUpdates.

3. Create a configuration file config.ini:

   Copy
   $ConfigFilePath = ".\config.ini"New-WindowsImageConfig -ConfigFilePath $ConfigFilePath

4. Open the created file and check the parameters:

   Copy
   wim_file_path=D:\Temp\install.wimimage_name=Windows Server 2016 SERVERSTANDARDCOREimage_path=D:\Win_Server_2016_img.qcow2virtual_disk_format=QCOW2image_type=KVMexternal_switch=externalvirtio_iso_path="D:\Drivers\virtio.iso"time_zone="Russian Standard Time"install_qemu_ga=Trueinstall_updates=Truepurge_updates=Falsecompress_qcow2=True

   Here:

   • external_switch=external — name of the created switch;
   • virtio_iso_path="D:\Drivers\virtio.iso" — full path to the ISO file with VirtIO drivers;
   • time_zone="Russian Standard Time" — the time zone, you can find out using the command tzutil /l;
   • purge_updates=False — do not clear the WinSxS directory after installing updates.

5. Run a local build of the image using the command:

   Copy
   New-WindowsOnlineImage -ConfigFilePath $ConfigFilePath

6. Wait for the operation to complete and make sure that the file D:\Win_Server_2016_img.qcow2 is created.

Use the CLI to import an image:

Copy
openstack image create --private --container-format bare --disk-format qcow2 --file D:\Win_Server_2016_img.qcow2 --property hw_qemu_guest_agent=yes --property store=s3 --property min_ram=2048 --property os_require_quiesce=yes --property min_disk=40 --property os_type=windows --property os_admin_user=Administrator --property mcs:lic:mswinsrv=true --property mcs_name='Windows Server 2016 Standard (en)' --property mcs_os_distro='server' --property mcs_os_edition='std' --property mcs_os_type='windows' --property mcs_os_lang='en' --property mcs_os_type='windows' --property mcs_os_version='2016' --property os_distro='win2k16' <image name>

Wait for the operation to complete. After downloading the image, you will be able to create a VM by standard means of the VK Cloud platform.

If you no longer need the imported image, delete it.
