[Xen-users] No network connectivity for domU in SuSE 10, Xen 3



Hey everyone, I'm asking this question again because 1. I Read as much as I could of the archives and still had no success, and 2. am not sure if the posts that I was reading actually pertained to Xen 2 or Xen 3. Here's what I'm hoping for some help with:

I'm running SuSE 10 (updated) with a SuSE 10 xm with xen-3.0_8259-0.1. The problem that I'm having is that I can get absolutely no network traffic to go from dom0 to domU, or anywhere else for that matter. I have tried using both DHCP and static addressing. The following information will be in regards to the static address scheme I was trying. Basically when domU boots, it doesn't bother to bring up the eth0 interface, bringing the interface up with an ifup will bring the interface up (and with dhcp it fails acquiring an address and backgrounds) but I am unable to ping any device on my network besides the address that is assigned to the domU machine itself. Dom0 networking is just fine. The bridge is up, the vif for the xm is up... something just isn't linking together here. I'll include all of my config information below and would appreciate any help with this. I've been working on this for days and am getting no where with it :(

On domainU I have the following:
linux:~ # brctl show

                                                                peth0

NOTE: doing a "route add default gw 192.168.1.1"  here does not fix the problem.
