28.7 Using a Bridge Network in a Virtual Machine
To create a virtual machine that makes use of the bridge network, use the virt-install --network option and specify the br0 bridge name. For example:
# virt-install --name MyFedora --memory 1024 --disk path=/tmp/myFedora.img,size=10 --network network=br0 --os-variant fedora28 --cdrom /home/demo/Downloads/Fedora-Server-dvd-x86_64-29-1.2.iso
When the guest operating system is running it will appear on the same physical network as the host system and will no longer be on the NAT-based virtual network.
To modify an existing virtual machine so that it uses the bridge, use the virsh edit command. This command loads the XML definition file into an editor where changes can be made and saved:
# virsh edit GuestName
By default, the file will be loaded into the vi editor. To use a different editor, simply change the $EDITOR environment variable, for example:
# export EDITOR=gedit
