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. The driver
path (64-bit) references
http://cdn.zstack.io/tools/renesas_usb30_21390.exe
.
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.
Add an Image
Add a Windows Server 2008 R2 image to ZStack Cloud. This image is used to install the operating system.
On the main menu of ZStack Cloud, choose Resource Center > Resource Pool > Compute Configuration > Image. On the Image page, click Add
Image. Then, the Add Image page is displayed. On
the Add Image page, set the following parameters:

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
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.

Backup Storage: Select an existing backup
storage.
Click OK. Then, the image is created.Figure 11. Create Image
Note: If your backup storage is ImageStore or Ceph, you can create an image
for a VM instance when it is in the running state. For other types of backup
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 backup storage type.
ImageStore backup storages
On the Image page,
click Actions > Export Image. Then, an image is exported.
After the image is

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