Cannot find device vmbr0 - failed to start raise network interfaces

[sdk229dak1]

Hi,

Just moved house and took my proxmox server with me. My IP address and gateway etc haven't changed so it should have all plugged back in fine but when I am booting up proxmox I am getting

Cannot find device vmbr0 -
Failed to get interface index : no such device
failed to start raise network interfaces

I have not made any changes to my /etc/network/interfaces so not sure why it's doing this all of a sudden.

Thanks

cat /etc/network/interfaces output:

auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

auto vmbr0
iface vmbr0 inet dhcp

auto vmbr1
iface vmbr1 inet dhcp

your vmbrX config is missing a lot options

il should be at minimum, something like

auto vmbr0
iface vmbr0 inet dhcp
    bridge_ports eno1
    bridge_stp off
    bridge_fd 0

Hi,

thanks for your reply. I will try this now.

Hi,

that did fix it. Although I'm very confused as it worked before for months without any of that?

Any ideas?
