Description of problem:
Baremetal always uses bonding with static IPs.
We require bond MAC == br-ex MAC because of old bugs.
Bug 2096413 - br-ex not created due to default bond interface having a different mac address than expected
https://bugzilla.redhat.com/show_bug.cgi?id=2096413
https://github.com/openshift/machine-config-operator/pull/3202
However with nmstate and OPNET-510 OVN no longer configures br-ex directly.
Because of the requirement we don't test unequal MACs so we don't know what OVN will do.
We should either alert when the MACs don't match or have OVN change the br-ex MAC itself.
ovs-vsctl set bridge br-ex other-config:hwaddr=$(cat /sys/class/net/bond0/address)
Version-Release number of selected component (if applicable):
4.18.0-0.nightly-2024-12-04-113014
How reproducible:
Always
Steps to Reproduce:
1. create nmstate with copy-from-mac: bond0
interfaces:
- name: bond0
type: bond
state: up
ipv4:
enabled: false
link-aggregation:
mode: balance-xor
options:
xmit_hash_policy: vlan+srcmac
balance-slb: 1
port:
- eno2
- eno3
- name: br-ex
type: ovs-bridge
state: up
ipv4:
enabled: false
dhcp: false
ipv6:
enabled: false
dhcp: false
bridge:
port:
- name: bond0
- name: br-ex
- name: br-ex
type: ovs-interface
state: up
copy-mac-from: bond0
ipv4:
enabled: true
address:
- ip: "192.168.111.110"
prefix-length: 24
ipv6:
enabled: false
dhcp: false
- name: eno1
type: interface
state: up
ipv4:
enabled: false
ipv6:
enabled: false
dns-resolver:
config:
server:
- 192.168.111.1
2. reboot until you hit a race condition
3.
Actual results:
bond0 MAC != br-ex MAC
Expected results:
The MACs should match.
