lxc_create_network_priv: 3463 Success - Failed to create network device (SOLVED)

[axel885]

Hi to all!
i don't know if it is a correct section and i looking for a solution but i can't. I have this problem, if i add a second network interface ( in this case a linux bridge) the container doesn't starts and return this error:



run_buffer: 571 Script exited with status 255
lxc_create_network_priv: 3463 Success - Failed to create network device
lxc_spawn: 1847 Failed to create the network
TASK ERROR: startup for container '113' failed


Thank to all for the help!

It is easier to access the text, if just the text is pasted here.

Hi everyone, I came across a similar issue when setting up a second bridge in Proxmox. Have you tried checking if the pve-firewall service is running properly?

This looks like a partial upgrade - can you send me the output of pveversion -v ?

You have a very old pve-firewall version (5.0.3) from 2023, but a very recent pve-container version (december 2024). There error is because the outdated firewall doesn't yet contain the function used in pve-container.

How did you update the server? We require updates to be made via apt dist-upgrade
