CIS configuration fails with an error "Kafka configuration failed: ErrInternalError: eth0: error fetching interface information: Device not found" while configuring Kafka service. This is because the server has a network device with 'em0' as identifier instead of 'eth0'.
To avoid this issue, perform the following:
Login to the server as a root user.
Run the following command:
yast2 lan
On Network Settings page under Overview tab, select a network device with em0 and click Edit.
On Network Card Setup page under Hardware tab, click Change and rename the Device Name to 'eth0' from 'em0'.
Click Next and then click OK.
