Otherwise, the cloud servers created from this image cannot start. If any data disks are attached, comment out or delete the configuration of these data disks from the /etc/fstab file.

Note

When registering an external image file as a private image, you are advised to perform the preceding operations on the VM where the external image file is located.
When registering a Windows external image file as a private image, if the Guest OS drivers are installed, the cloud platform will check the image file after you select Enable automatic configuration. If the GuestOS drivers are not installed, the cloud platform will try to install them.
