Please update to 4.0.0 final, or even 4.0.1-rc version.. 
many bugs fixed after 4.0.0-rc6.

Xen doesn't have drivers for hardware/nics. It's the Linux dom0 kernel that has 
the NIC driver.
Does "lspci -v" list the nic (when booted to Xen dom0)? 

Also please paste your dmesg.

Also is there a specific reason you're using 2.6.29-xen-r4 (xenlinux) kernel
instead of the pvops dom0 kernel?
