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
