network bridge deleted after restart

i want to create a network bridge to use xen. i ran those commands

# ip link add name xenbr0 type bridge
# ip link set xenbr0 up
#ip link set enp0s25(my interface) master xenbr0
#dhcpcd xenbr0

and confirmed working, it shoes up when i type ip link

oddly, whenever i restart this configuration isn't saved. any ideas?

You can create a oneshot systemd service that Exec's a script that contains these commands (do include a

#!/bin/bash

line and the +x permission)

How do you configure your network?

Both systemd-networkd and netctl have support for bridges in their configuration files, this is all documented in thee wiki.

Re: network bridge deleted after restart

i've created the bridge with iproute as described in my first post. i understand now that it wasn't enough and i have to configure a service that runs at startup and configures the bridge every time using this method
i just followed this section of the wiki
i'l try configuring the bridge with a different method as you suggested and let you know if it helps. if not a manual systemd service might do the job

Re: network bridge deleted after restart

Hi guys, I've the same problem. Successfully created the bridge (for KDE/QEMU use) but the config is not persistent.
After reboot I need to set it up again from scratch.
What's the best approach you found to solve the problem?
Thank you very much in advance.
