Issue with setting up bridge networking
Issue with setting up bridge networking
I've just switched from Fedora to Debian 12 and I can't seem to get bridge networking to work. I've followed the official guide and edited the /etc/network/interfaces. I double checked and everything is correct. I rebooted the system but my ethernet stopped working altogether. Are there any updated guides and common pitfalls that I should keep in mind. I need the bridge for kvm.
You're viewing a single thread.
I'd get rid of that old networking and use NetworkManager like on Fedora.
You need to add the IP on the bridge, not the underlying NIC, but you probably know that already.
Yes I tried that but the VMs still can't connect to it. I did the same setup as in Fedora but it doesn't work
I can't find my notes on how I got this to work on Debian 11 but, if I recall correctly, I had to disable NetworkManager and setup networking directly via /etc/network/interfaces. I no longer have Debian running but at the time this worked for me:
source /etc/network/interfaces.d/* # The loopback network interface auto lo iface lo inet loopback # The primary network interface # allow-hotplug eno1 auto br0 iface br0 inet dhcp bridge_ports eno1
