I have a single ubuntu VM setup on my machine for running a variety of tasks where dockers are not the best option. Recently my VM appears to have lost the network bridge configuration from the form view (see the first attachment). Additionally, the XML (see spoiler below) does not appears to contain any reference to the br0 interface. This makes sense as my poking around in ubuntu itself does not seem to show any current network interfaces at all.
I have restarted the server, the docker and VM services, and the network bridge without any changes.
Can anyone help in getting reconfiguring the VM for network bridge access or an alternative option?
Please let me know if any log or other files would help.
