What Should I Do If an ECS Created from an Image Using the UEFI Boot Mode Fails to Start?

Symptom

An ECS created from an image using the UEFI boot mode fails to start.

Possible Causes

The image OS uses the UEFI boot mode, but the uefi attribute is not added to the image attributes.

Handling Method

  1. Delete the ECS that fails to start.
  2. Call the API to update the image attributes and change the value of hw_firmware_type to uefi.

    API URI: PATCH /v2/cloudimages/{image_id}

    For details about how to call the API, see Image Management Service API Reference.

  3. Use the updated image to create an ECS again.
