Xen users - Aug 2006 - second interface eth1 does not work in domU (xen 3.0.2 binary install in mandriva 2006)

i tried to set up 2 bridged nics in my domU as specified in:
 
 
http://wiki.xensource.com/xenwiki/XenNetworking
 
1. 
In /etc/xen/xend-config.sxp:

(network-script my-network-script)
2.
my-network-script should read

#!/bin/sh
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0
"$dir/network-bridge" "$@" vifnum=1
 
3. restart xend and xendomains
 
4. in domU config:
 
vif = [ ''ip=128.48.123.146, bridge=xenbr0'',
''ip=128.48.106.156, bridge=xenbr1'' ]
 
5. lo behold, i got 2 nics in domUI (both eth0 and eth1 works fine in dom0 so
there is no physical problem).
 
unfortunately, eth1 does not work, as it only send and does not receive, while
eth0 works fine as before.

any suggestions would be most welcome:

to answer my own question. the script should specify netdev:
 
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0 netdev=eth0
"$dir/network-bridge" "$@" vifnum=1 netdev=eth1
[
now it works. hopefully it will be useful for others.
