A Windows template is a VM image where a Windows VM instance with
installed necessary software such as drives and QGA removes and then regenerates its
security identifier (SID, a unique identifier of a user, user group, or computer
account). This template can be mainly used to create VM instances in bulk in a custom
manner. This Tutorial supports the following versions:
Windows version: Windows Server 2008 R2, Windows Server 2012 R2, Windows 7,
Windows 10, Windows Server 2016, and Windows Server 2019.
ZStack Cloud version: 3.7.1 or later.
Environment Preparation
To encapsulate a template, prepare the following software or tools:
Make sure that you obtain a Windows image from the
Microsoft official website as needed, and ensure your compliance of relevant
authorizations and permissions. This Tutorial
referencescn_windows_server_2008_r2_standard_enterprise_datacenter_and_web_with_sp1_x64_dvd_617598.iso.
Optional. USB 3.0 driver:
USB 2.0 driver is native to Windows Server
2008 R2. Install USB 3.0 driver as needed. Contact ZStack official technical support to obtain an applicable driver file.
Template
This Tutorial includes two types of encapsulation method: Windows and Windows VirtIO.
Encapsulation procedures for each method are different. Make sure that you perform
relevant operations according to the corresponding method as follows:
Windows: Add an image by using Windows platform type. Note that the
template with the Windows method has two types of drive: IDE and VirtIO. For
more information about how to encapsulate a template with the Windows method,
see Windows Template.
Windows VirtIO: Add an image by using Windows platform type and enable
Virtio. Note that the template with the Windows VirtIO method has only one type
of drive: VirtIO. For more information about how to encapsulate a template with
the Windows VirtIO method, see Windows VirtIO Template.
Windows Template
To encapsulate a Windows template, follow these steps:
Add an image.
Install an operating system.
Install GuestTools and other software.
Prepare the operating system.
Create a system template.
The following details the whole process of how to encapsulate a Windows Server 2008 R2
template.

and their later versions.
Note:
For a Windows-based VM instance (such as
Windows Server 2012 R2, Windows Server 2016, and Windows 10)
booted by UEFI, the following page will be displayed after
the VM instance starts. Press any key to continue the
installation of the VM operating system. Otherwise, the VM

Open the CMD command line by using the administrator permission.
Go to the C:\Windows\System32\sysprep directory and run the
Sysprep tool.
Configure preparation policies and perform relevant operations. You can complete
this step by setting the following parameters:
System Cleanup Action: Select Enter System
Out-of-Box Experience (OOBE).
Generalize: Select this checkbox. Then, the VM
operating system created from the template has a unique security
identity (SID).
Shutdown Options: Select Shutdown.
Click OK. Then, the system
preparation begins.Figure 10. System Preparation
Allow Execution of Third-Party Scripts:
In the VM instance, run the
command Set-ExecutionPolicy RemoteSigned -Force to allow
the execution of third-party scripts, ensuring that platform functions such
as network configuration delivery, reading, and script execution can work
properly.
Create a System Template
After you create the operating system template successfully, you can
create VM instances in bulk in a custom manner by using this image. Also, you can export
this image to create VM instances in other cloud platforms.
Create a VM Image
On the VM Instance page, select the target VM
instance and create an image for the VM instance.
On the Create Image page, set the following parameters:
Name: Enter a name for the image.

a VM instance when it is in the running state. For other types of image storage,
you need to stop the VM instance before you can create an image.
Export the Image
Exported images can be used directly by other cloud platforms to
create VM instances. The export method varies based on the image storage type.
ImageStore image storage
On the Image page,
click Actions > Export Image. Then, an image is exported.
After the image is
generated, you can download the exported image by copying the image URL
on the Overview tab page of the image details
page.

On the Overview tab page of
the created image, copying Image Storage Path
will prompt you for the corresponding information such as pool and image
in the Ceph image storage. After you copy this image path, you can
export the Ceph image by running rbd on the Ceph
image storage. Assume that the storage path of the Ceph image storage is
ceph://bak-t-c9923f982/61ece0adc72, run the
following
command:
[root@ceph-node1 ~]#rbd export bak-t-c9923f982/61ece0adc72 /root/export-test.image
