How long does it take to create a custom image based on an existing cloud computer?
It takes about 10 to 15 minutes to create a custom image based on an existing cloud computer. The actual required time varies with the data size of the cloud computer.
What do I do if I always fail to create a custom image?
The following table describes the possible causes of an image creation failure and the corresponding solutions.
Possible cause | Solution |
The administrator installs antivirus software on the cloud computer that is used to create the custom image. During image creation, the software disables the Elastic Desktop Service in the image. As a result, the image fails to be created. | Ask the administrator to uninstall such software from the cloud computer and then try to re-create the custom image. |
During image creation, the administrator changes the image of the cloud computer that is used to create the custom image. As a result, an image conflict occurs and the image fails to be created. | Ask the administrator not to change the image of the cloud computer during image creation. |
During image creation, the administrator deletes the cloud computer that is used to create the custom image. As a result, the image fails to be created. | Ask the administrator not to delete the cloud computer during image creation. |
