Setting the driver name to q emu forces packet processing into qemu user space, effectively disabling

vhost-net for that interface.

11.3. Bridged net working wit h 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

Important

NetworkManager does not support bridging. NetworkManager must be disabled to use

networking with the network scripts (located in the /etc/sysco nfi g /netwo rk-scri pts/

directory).

# chkconfig NetworkManager off

# chkconfig network on

# service NetworkManager stop

# service network start

If you do not want to disable Net wo rkMan ag er entirely, add " NM_CONTROLLED=no" to the

i fcfg -* network script being used for the bridge.
