Hi,

Thanks for your suggestion. Unfortunately, they don't seem working in my
case. I have attached some more information, hope you can help find some
clues here:

After I do ' /etc/xen/scripts/network stop', the network starts working,
and this is the result of brctl show:
bridge name bridge id STP enabled interfaces
xen-br0 8000.000000000000 no can't get port
info: Function not
implemented

Then I do '/etc/xen/scripts/network start', the network dies again, and
this is the result of brctl show:
bridge name bridge id STP enabled interfaces
xen-br0 8000.feffffffffff no eth0
vif0.0
By the way, I got following error when I do start:
*network start bridge=xen-br0 netdev=eth0 antispoof=yes
iptables: No chain/target/match by that name

No use to remove eth0 and add it again. And it seems that I cannot unload
tg3 module between that. No matter I do 'rmmod tg3' or 'rmmod -f tg3', the
module is still there ...

What is more, if I try to ssh to some other machine after the network
dies, I got following errors prompting on my screen:
vif0.0: received packet with own address as source address

Do you have any further suggestions? Thank you very much!

Regards,
Wei Huang
