I recently created a bridge for my VMs inside cockpit ( Ubuntu LTS Server -20.x) and used it in my VMs. They work fine.
My understanding of cockpit was that it will use system configuration files for its tasks but however opening up my netplan configuration at /etc/netplan/00-installer-config.yaml I can see no definition for the bridge ( br0 ).
So any idea where the bridge configuration is kept when its created via cockpit ?
UPDATE 2 :
Solved. See answer
As advised by @user535733 I have also looked at locations:
but no br0 related settings there.
