Red Hat Virtualization can configure multiple Virtualization network bridges to use with multiple ethernet cards. To successfully configure multiple network bridges for ethernet cards, you must configure the second network interface by either using the system-config-network TUI/GUI, or by creating a new configuration file in /etc/sysconfig/network-scripts . You should use a process to setup multiple Xen bridges. This is an example config file for a second NIC called 'eth1' : 
#/etc/sysconfig/network-scripts/fcfg-eth1
DEVICE=eth1
BOOTPROTO=static
ONBOOT=yes
USERCTL=no
IPV6INIT=no
PEERDNS=yes
TYPE=Ethernet
NETMASK=255.255.255.0
IPADDR=10.1.1.1
GATEWAY=10.1.1.254
ARP=yes
Copie o /etc/xen/scripts/network-bridge para /etc/xen/scripts/network-bridge.xen .
Edit /etc/xen/xend-config.sxp and add a line to your new network bridge script (this example uses "network-virtualization-multi-bridge" ).
No arquivo xend-config.sxp , a nova linha deve refletir seu novo script: 
network-script network-xen-multi-bridge
Não esqueça de descomentar a linha contendo: 
network-script network-bridge
Se você quiser criar pontes Xen múltiplas, você deve criar um script padronizado. Este exemplo abaixo cria duas pontes Xen (chamadas de xenbr0 e xenbr1 ) e conecta-as ao eth1 and eth0 , respectivamente: 
# !/bin/sh
# network-xen-multi-bridge
# Exit if anything goes wrong
set -e
# First arg is operation.
OP=$1
shift
script=/etc/xen/scripts/network-bridge.xen
case ${OP} in
start)
$script start vifnum=1 bridge=xenbr1 netdev=eth1
$script start vifnum=0 bridge=xenbr0 netdev=eth0
;;
stop)
$script stop vifnum=1 bridge=xenbr1 netdev=eth1
$script stop vifnum=0 bridge=xenbr0 netdev=eth0
;;
status)
$script status vifnum=1 bridge=xenbr1 netdev=eth1
$script status vifnum=0 bridge=xenbr0 netdev=eth0
;;
*)
echo 'Unknown command: ' ${OP}
echo 'Valid commands are: start, stop, status'
exit 1
esac
Se você quiser criar pontes adicionais, use o script amostra e copie o arquivo de forma apropriada.
