What is image?

Image is the template for CVM software configuration (operating system, pre-installed programs, etc.). Tencent Cloud requires users to launch the instance via image. An image can launch more than one instance so that users can repeatedly use it. For more information on image, please see Image Overview.

What preparations do I need to make before importing an image?

Before importing an image, two major steps need to be completed: applying for permissions and preparing image files. For more information, please see Import Image.

What if a Windows system custom image fails to be created?

If a Windows system image fails to be created, perform a check following the steps below.
(1) Check and make sure the following services and all the services coming from the official source of Tencent Cloud and starting with Win_Agent are working properly:

Program Name Installation Location Service Name
QcloudService.exe C:\Windows\ Qcloud service
WinAgent.exe C:\WinAgent\ WinAgent Display Name
win-agent.exe C:\win-agent\ win-agent

(2) The creation of a custom image relies on the Windows Modules Installer provided by Microsoft. Make sure this service is working properly.

(3) Some anti-virus tools or Safedog may block custom image creation scripts. To avoid creation failure, it is recommended that you close these tools before creating a custom image.

(4) If the image creation tool is interrupted by system pop-ups, remotely log in to the CVM, and then check and adjust the CVM settings to avoid pop-ups.
