11.3. Bridged Networking with libvirt

Bridged networking (also known as physical device sharing) is used to dedicate a physical device to a virtual machine. Bridging is often used for more advanced setups and on servers with multiple network interfaces.

To create a bridge (br0) based on the eth0 interface, execute the following command on the host:

# virsh iface-bridge eth0 br0

# chkconfig NetworkManager off
# chkconfig network on
# service NetworkManager stop
# service network start
