Engineering Team, which is subscribed to cloud-init. https://bugs.launchpad.net/bugs/1919045 Title: wrong HWADDR on interface when ethernet_mac_address is given on the bond Status in cloud-init: Expired Bug description: creating a configuration for an active-backup bond: ``` cloud-init devel net-convert -p network_data.json -k network_data.json \ -d /tmp -D rhel -O sysconfig \ -m eno50,b2:35:4a:42:42:ed -m eno53,b2:35:4a:42:42:ee ``` with cloud-init (cloud-init-19.4-7.el7_9.3.x86_64, cloud-init-20.3-10.el8.noarch) assuming there is a ethernet_mac_address defined on the bond: ``` { "id": "bond0", "type": "bond", "ethernet_mac_address": "b2:35:4a:42:42:ed", "bond_mode": "active-backup" ... ``` we see cloud-init creates a file ifcfg-eno53 wrongly containing a HWADDR with the address of the bond. For a bond, we expect both interfaces to display the same mac when running ip link (default behavior with fail_over_mac=0 bonding module parameter). However, the HWADDR in the ifcfg file must retain the original mac address of the interface, or the interface is not configured correctly. Practically, it is never configured as slave. Workaround seems to just remove the "ethernet_mac_address" on the bond there (I originally added it because it is required according to https://github.com/openstack/nova/blob/master/doc/api_schemas/network_data.json, which I was using to validate my network_data file). I would expect the ifcfg-eno53 mac address to not be impacted by the presence of ethernet_mac_address on the bond. For reference I attach my network_data.json if anyone wants to try.
