KB40051: "License Manager failed to generate the Activation XML file." error message appears when activating the Intelligence Server 9.x on a Linux operating system through the License Manager graphical user interface

 
Error message:

License Manager failed to generate the Activation XML file. 
Please restart this machine and try again.

 
Additionally when activation is done through the License Manager console view the following message is shown:

Error message:

Exception from Registration Client while generating XML file for activation! 
Error code: -14 Error message: Failed to retrieve MAC Address line :70 
(unknown message -14)

 
Note: The License Manager GUI does not show the error message for the reason the Activate.XML file cannot be generated. By testing via the console License Manager a more verbose explanation is given.
 
CAUSE:
 
When a Strategy Intelligence Server 9.x running on Linux is being activated, the MAC address is retrieved from the interface 'eth0'. If the user has no Network Interface Card (NIC) configured under the 'eth0' interface or has renamed the NIC from 'eth0' to a different name, the XML file generation will fail. 
 
ACTION:
 
User should configure a NIC under the 'eth0' interface and name it 'eth0' to be able to generate the Activate.xml file and continue with the Strategy Intelligence Server activation.
