Hi,
Well, I'm ready to try this and here are my first problems.
the box already has two physical nic. eth0 and eth1. these work fine.
*****************************
So I do on dom0:
/etc/network/interfaces
auto dummy0
iface dummy0 inet static
address 192.168.6.1
netmask 255.255.255.0
network 192.168.6.0
broadcast 192.168.6.255
/etc/xen/scripts/my-network-bridge
#!/bin/bash
case "$1" in
start)
/etc/xen/scripts/network-bridge start bridge=xenbr0
netdev=eth0 vifnum=0 antispoof=no
/etc/xen/scripts/network-bridge start bridge=xenbr1
netdev=eth1 vifnum=1 antispoof=no
/etc/xen/scripts/network-bridge start bridge=xenbr2
netdev=dummy0 vifnum=2 antispoof=no
;;
stop)
/etc/xen/scripts/network-bridge stop bridge=xenbr0
netdev=eth0 vifnum=0
/etc/xen/scripts/network-bridge stop bridge=xenbr1
netdev=eth1 vifnum=1
/etc/xen/scripts/network-bridge stop bridge=xenbr2
netdev=dummy0 vifnum=2
;;
restart)
$0 stop
$0 start
;;
*)
echo "usage: $0 {start|stop|restart}"
esac
exit 0
Alternatively, you could just skip the my-network-bridge custom script
and put it all in /etc/network/interfaces. For example:
auto eth0
iface eth0 inet manual
pre-up ip link set eth1 addr fe:ff:ff:ff:ff arp off
auto xenbr0
iface xenbr0 inet manual
bridge_ports eth0
bridge_stp off
bridge_fd 0
auto eth1
iface eth1 inet manual
pre-up ip link set eth1 addr fe:ff:ff:ff:ff arp off
auto xenbr1
iface xenbr1 inet manual
bridge_ports eth1
bridge_stp off
bridge_fd 0
auto dummy0
iface dummy0 inet static
address 192.168.6.1
netmask 255.255.255.0
network 192.168.6.0
broadcast 192.168.6.255
auto xenbr2
iface xenbr2 inet manual
bridge_ports dummy0
bridge_stp off
bridge_fd 0
