the thing is there is no eth0 in the machine at all. Appreciate your support. Thanks

The issue resolved, The issue was static route not configured properly in node-2, Thanks

@albarki - Glad to hear you were able to find the problem! That "failed to add IP addr" error is a bit vague, and I probably wouldn't have thought of checking the static route. In the cases where I've seen this error, there's been a syntax error in the CNI network config.

@leblancd Thanks for that great repository.
