How Do I Make a System Disk Image Support Fast ECS Creation?
Scenarios
Fast Create greatly reduces the time required for creating ECSs from a system disk image. Currently, this feature is supported by all newly created system disk images by default. Some existing system disk images may not support this feature, you can make them support it through image replication.
For example, if image A does not support fast ECS creation, you can replicate it to generate image copy_A that supports fast ECS creation.
Constraints
Full-ECS images and ISO images cannot be configured using this method.
Check Whether an Image Supports Fast ECS Creation
- Access the IMS console.
- Log in to the management console.
- Under Compute, click Image Management Service.
The IMS console is displayed.
- Click the Private Images tab to display the image list.
- Click the name of the target image.
- On the displayed image details page, check the value of Fast ECS Creation.

- Locate the target system disk image, click More in the Operation column, and select Replicate from the drop-down list.
The Replicate Image dialog box is displayed.
- Set Replication Mode to Within Region and set other parameters based on Replicating Images Within a Region.
- After the image is successfully replicated, the generated image can be used to quickly create ECSs.
