Hi all,
Debian squeeze 2.6.32-5 with Xen 4.0
I'm having some issues getting PCI passthrough to work for a quad port
Gigabit NIC card. I've added the devices and they are not visible in
dom0, however when the domU boots up all I get is the following:
[ 0.644428] Intel(R) Gigabit Ethernet Network Driver - version 1.0.8-k2
[ 0.644433] Copyright (c) 2008 Intel Corporation.
[ 0.644838] PCI: Setting latency timer of device 0000:00:00.0 to 64
[ 0.655956] igb: probe of 0000:00:00.0 failed with error -2
lspci shows the following in the domU:

Does anyone have any ideas what I might be doing wrong or how I can debug this
further?
Best Regards,
