[Bug 1753431] Re: bonding does not works

[Mathieu Trudel-Lapierre]

Your original config in comment #1 is correct: you must specify the
underlying devices, because those names are matched later for
"interfaces:" in the bond config.

The issue with 802.3ad is likely a driver issue or a bug in systemd; the
right mode needs to be set by networkd (which may require rebooting
rather than just running 'netplan apply').

Reassigning to systemd for investigation, we do have unit / autopkg
tests running for netplan which look like 802.3ad is correctly set, but
they do not interact with other network devices (there are no other
network devices in the test environment).

Furthermore, is anything beyond the physical network adapters configured
to used 802.3ad? This is important for the bonding to work.

** Package changed: nplan (Ubuntu) => systemd (Ubuntu)

Title:
  bonding does not works

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  I'm working on libvirt/kvm hypervisor
  I user 2 bondind interfaces:
  eno1 + eno2 => bond0 via "netplan" ("service" interface for hypervisor)
  eno3 + eno4 => bond1 via "ifupdown" ("virtualization" interface for libvirt)

  Since last upgrade (today), i got "Warning, no 802.3ad response from
  the link partner ..." with dmesg, bonding doesn't longer works with
  "netplan" and "ifupdown".

  Kernel problem ? ifenslave problem ?
