Posted a wrong config for br0.netdev. the correct one is the following

br0.netdev

[NetDev]
Name=br0
Kind=bridge

[Bridge]
DefaultPVID=1
VLANFiltering=yes

the interface eth.1 correctly gets UP and it receives the IP addr from the primary lan. when I connect my libvirt VMs to the br166 unfortunately they do not get any IPs from the VLAN 166 (DHCP is there so they should get it).

I'm sure my networkd config is off in some parts but not sure where. conceptually it should be correct.
