Physical interfaces are only used by bonding interfaces.
- bond0 have an ip address
- bond1 is user by bridges and vlans
I've solved my problem:
- by adding LACP parameters at module loading:
/etc/modprobe.d/netcf.conf
alias bond0 bonding
alias bond1 bonding
options bonding mode=4 lacp_rate=1 xmit_hash_policy=2 miimon=100 downdelay=200
updelay=200
- and nothing about bonding mode in ENI and netcfg.yaml !
My servers are "KVM/Libvirt" hosts.
* Bond0 is my "service" interface to the host
/etc/netplan/01-netcfg.yaml (yaml)
# Exemple de configuration des interfaces réseau pour l'hyperviseur
# => '/etc/netplan/01-netcfg.yaml'
#
# => 2 ports / LACP
# => La configuration des interfaces de virtualisation DOIT être effectuée
# via '/etc/network/interfaces'

* Bond1 is used by VMs.
Note that Virt-manager NEEDs access to /etc/network/interfaces to work properly
!!
I put "bond1" configuration in a included file
(/etc/network/interfaces.d/bond1) of ENI because i don't want to allow any
change on it by Virt-manager. So Virt-manager has only access to vlan/bridges
interfaces.

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 ?
