[Xen-devel] Network stops responding after some time

[Adnan Khaleel <adnan@xxxxxxxxxx>]

Hi there,

I'm using the Suse Enterprise 10 RC2 along with Xen 3.0.2 on X86-64 and I'm 
experiencing a problem with the network.
I boot into the Xen kernel and everything works just fine. I can browse the net 
etc.
However after a while the network stops responding completely. I am not sure 
what causes this to happen or what triggers it. After a few hours, the network 
just stops working.

Doing an ifconfig -a before and after gives me the following

I am not sure what else would be helpful in diagnosing the problem. Does 
anybody has any ideas on what else I should be checking?

Thanks
