I can't seem to get the network right.

here is my xend-config:
        (xend-http-server yes)
        (xend-relocation-server yes)
        (xend-address localhost)
        (xend-relocation-address localhost)
        (network-script network-bridge)
        (vif-script vif-bridge)
        (dom0-min-mem 196)
        (dom0-cpus 0)

my vm config:
        kernel = "/boot/vmlinuz-xen"
        ramdisk = "/boot/initrd-xen"
        memory = 256
        name = "apollo"
        nics=1
        vif = ['mac=AA:00:00:00:00:01, ip=192.168.0.2, vifname=apollo']
        gateway="192.168.1.1" 
        disk = [ 'phy:xenvg/apollo,hda1,w' ]
        netmask="255.255.255.0"
        hostname= "apollo"
        root = "/dev/hda1 ro"
        extra = "4"

As you can see there is no interface in apollo,  what have I done wrong?
Also can someone post a sample wrapper script for bridging 3 nics?
