XEN in SLES 10 SP2 and multiple NIC - again with the domU

[kjhurni]

I thought I had this all squared away, but apparently not

SLES 10 SP2 64-bit Host
two physical NIC's

eth0
eth1

eth0 I want for Dom0
eth1 I want for DomU

But the ethernet NIC are on two physically diff. networks (so eth0 for Dom0 management)

I used Rainer's script to create two bridges
I only assigned an IP to eth0
I left eth1 as "unconfigured"

I go into the VM and when I add a NIC to it, I get two choices:
Virtual Network
or
Physical Device

I chose physical device, peth1 (my only other choices in the pulldown was peth0)

I fired up my DomU (sles10 sp2 32-bit) and it sees the NIC. I give it an IP, netmask and default gateway that's on the network that the ETH1 NIC is plugged into

But I'm unable to ping anything or have another machine access that DomU

I'm sure I did something stupidly wrong.

Now, if I actually give ETH1 (in the Dom0) an IP and adjust the routing so that there's a route to network, then the DomU can get access to "other" things.

I see something about pciback, but the communities article is for sles 10 sp1, not sp2 and I know that things changed.

I tried examining Rainer's Power Point slides but it didn't really make sense to me (we don't use bonding and have no desire to do bonding).
