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?
