Thread-topic: Networking problems at xend start 
I am running Xen on a Dell Precision 470. The box has two Intel Xeon
EMT64 procs with hyperthreading enabled with 2 Gigs of RAM.I am running
SUSE Sles 9.

I am noticing that when I bring up xend on a machine with 2 ethernet
cards, Dom 0 loses networking. I can still see the machine from within
the subnet it belongs to, but it has no visibility outside.
The machine has a Dell 82545M Gigabit Ethernet controller set up as eth0
and an intel Etherexpress pro 100 server adapter set up as eth1.

I have included the ifconfig output before and after xend start.
I have also included netstat-rn output with and without the intel
eepro100 

I don't see any messages on the serial output.

Is any one else seeing similar problems?

Raj
