I'm running a PV DomU on CentOS 4. I was able to successfulyl hide a
e1000 PCI card by appropriately modifying /etc/modprobe.conf. The
device is not configured as a eth device in my dom0. I was also able
to successfully load it in my domU and e1000 driver loads fine.
ifconfig shows correct configuration of IP address.

However, I'm not able to access the network. The network was
accessible with the same IP using vif interface instead. Kindly help.

Any ethernet or interrupt related messages in dmesg on dom0 or domU or from xm dmesg?

Research the noirqdebug/pollirq/swiotlb settings and try some combinations
