Scenario

Binding key pair applies to updating the key pair of the created cloud server.

If the Linux cloud server you create is not bound to an SSH key pair, this feature can bind a key pair to the cloud server; If the Linux cloud server you create is bound to an SSH key pair, this feature can update the key pair for the cloud server.

Limitations

This feature is only applicable to Linux OS and not to Windows OS.

This feature is only available to cloud servers with the status of Running.

If you are using a private image that does not have qga installed (usually the image uploaded by the user does not have qga), this feature will not work.
