I am preparing migration of an UBUNTU 16.04.7 server with 5 NIC's to 20.04. My testing server has 4 NIC's: 2 onboard and 2 as Intel Pro NIC. Configured in 00-installer-config.yaml. The first NIC is configured as:
version: 2
renderer: networkd
ethernets:
enp65s0f0:
addresses: [10.1.11.230/24]
gateway4: 10.1.11.11
nameservers:
addresses: [10.1.11.11, 1.1.1.1]
enp193s0f0:
optional: true
enp193s0f1:
optional: true
enp65s0f1:
optional: true
This part works. The next 3 NIC's are going to be bond0, with vlans on top and bridges:
bonds:
bond0:
interfaces: [enp193s0f0, enp193s0f1, enp65s0f1]
parameters:
mode: 802.3ad
lacp-rate: fast
mii-monitor-interval: 100
min-links: 1
vlans:
vlan1:
id: 1
link: bond0
vlan11:
id: 11
link: bond0
vlan240:
id: 240
link: bond0
bridges:
br100:
interfaces: [vlan1]
br11:
interfaces: [vlan11]
br240:
interfaces: [vlan240]
The bond0 does not work. I have searched and tried all kinds of variations with ordering of NIC's, dhcp4: false, dhcp6: false, optional:true only using the IntelPro NIC's for the bonding. I have reviewed answers on this and other forums, but no solution so far yet.
- What's wrong with my configuration? Anything missing?
- Is the architecture I am aiming at still supported? I want my KVM guests to use a bridge so they can communicate with each other without needing the physical switch and without needing VLAN to be configured in the guests. This worked perfectly in Ub16.04.
My switch is a HP V1910-24G and has 4 other working trunks (LACP/802.3ad), with the Ub16.04 (4 NIC's)server and 3 QNAP NAS's with each a double NIC.
See the following outputs on my Ubuntu 20.04 with the above netplan config:

I am at the end of my options and ready to remove cloud-init/netplan and revert to the working configuration I had in 16.04. Thanks for reading this far.
