Importing an Image File Quickly

Function

This API is used to quickly create a private image from an oversized external image file that has uploaded to the OBS bucket. Currently, only ZVHD2 and RAW image files are supported, and the size of an image file cannot exceed 1 TB.

The fast image creation function is only available for image files in RAW or ZVHD2 format. For other formats of image files that are smaller than 128 GB, you are advised to import these files with the common method.

The API is an asynchronous one. If it is successfully called, the cloud service system receives the request. However, you need to use the asynchronous job query API to query the image creation status. For details, see Querying the Status of an Asynchronous Job.

Constraints

Before importing image files, ensure that the file format is RAW or ZVHD2 and the following have been done:
  • RAW image files have been optimized, and bitmap files have been generated.
  • ZVHD2 image files have been optimized as required.

For details about how to convert the image file format and generate a bitmap file, see Quickly Importing an Image File.
