I have two files for the bridge;
/etc/NetworkManager/system-connections # cat br0\ port\ 1.nmconnection
[connection]
id=br0 port 1
type=ethernet
interface-name=enp8s0
master=br0
slave-type=bridge
[ethernet]
mac-address=88:C9:XX:XX:XX:XX
[bridge-port]
/etc/NetworkManager/system-connections # cat Bridge\ connection\ enp8s0.nmconnection
[connection]
id=Bridge connection enp8s0
type=bridge
interface-name=br0
[ethernet]
[bridge]
[ipv4]
method=disabled
[ipv6]
addr-gen-mode=stable-privacy
method=disabled
[proxy]
You see the new way of interface naming… you can always alias the connection via;
#Set altname to eno1
ip link property add dev eno1 altname eth0
A bridge is a bridge, nothing to do, it’s on the vm where the connection static/dhcp is done
