23.1 Getting the Current Network Settings
A network bridge can be created using the NetworkManager command-line interface tool (nmcli). The NetworkManager is installed and enabled by default on Fedora 31 systems and is responsible for detecting and connecting to network devices in addition to providing an interface for managing networking configurations.
A list of current network connections on the host system can be displayed as follows:
# nmcli con show
NAME UUID TYPE DEVICE
Wired connection 1 3a3fecfc-e571-35ee-89c4-47a6e0e120c0 ethernet eno1
virbr0 d66ead56-e941-4c00-bd98-b8f3cbaaf4f3 bridge virbr0
In the above output we can see that the host has an Ethernet network connection established via a device named eno1 and the default bridge interface named virbr0 which provides access to the NAT-based virtual network to which KVM guest systems are connected by default.
