Networking problem with Xen on openSuse 10.3

Hi,

I am still stuck with the network problem.
I searched the archive of maling list and found an user has the same problem.
Re: [Xen-users] xenbr0, no peth0, problem with network configura - Xen Source
And the reply suggests to execute "ethtool -K eth0 tx off "
When I executed it, nothing happens. Should I execute this command at boot time?I have tried the trouble shooting solutions from Installing Xen3 - openSUSE
But still no luck.
How can I do that?
So I didn’t get the answer from that thread.
Here is my output of ifconfig:

As you can see, no peth0 and vif0.0.

The output of brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.003048637276 no eth0

No vif interface.

Does anyone have the same problem?

This problem is quite annoying.
Actually, I want to make domains can communicate with each other, suck like uploading files from Dom 0 to Dom 1. I really don’t know how to achieve this without bridging.
If you have any workaround solution, please kindly let me know.
I have to use opensuse 10.3 with xen. No other limitations.
Any response is appreciated. Thanks again.
