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 RHEL 8 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
eno1 99d40009-6bb1-4182-baad-a103941c90ff ethernet eno1
virbr0 7cb1265e-ffb9-4cb3-aaad-2a6fe5880d38 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.
Similarly, the following command can be used...
