Public bug reported: NetworkManager will attempt to manage all network interfaces with no configuration. To ignore an interface, you need to specify an ifcfg file in /etc/sysconfig/network-scripts to include "NM_CONTROLLED=no".
Currently, cloud-init does not have support for the NM_CONTROLLED option or any way for a data source to explicitly generate config to tell NetworkManager to ignore a particular interface. This functionality is currently possible with Netplan, and this report is a request for feature parity in NetworkManager config rendering. ** Affects: cloud-init Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
