How to delete lxdbr0 from ifconfig and use a manually created bridge from /etc/network/interfaces?

I tried deleting the network however it didn’t allow me to even after I stopped the containers which use it.

greg@machine:~$ lxc network delete lxdbr0 
error: The network is currently in use
greg@machine:~$ lxc network list

|  NAME   |   TYPE   | MANAGED | DESCRIPTION | USED BY |

| br0     | bridge   | NO      |             | 0       |

How to replace lxdbr0 with a manually created bridge?

lxc network show lxdbr0 would tell you exactly what’s using it.

My guess is that you have your default profile using the bridge, so you’d want to do lxc profile edit default, replace lxdbr0 by br0 in there, then you should be able to remove lxdbr0 as there won’t be any remaining reference to it.

HI,

I have similar issue but editing the default profile is giving this
Config parsing error: Device validation failed for "eth0": Failed loading device "eth0": Failed to load network "br0" for project "default": Network not found

and cant write the changes to the default profile.

Is their any work around to this ?

EDIT

Found solution here:
