Here's what I tried:

These are devices I wanted to pass through:

lspci -n | grep 07:00

07:00.0 0c04: 11f8:8032 (rev 05)
07:00.1 0c04: 11f8:8032 (rev 05)
07:00.2 0c04: 11f8:8032 (rev 05)
07:00.3 0c04: 11f8:8032 (rev 05)

I started following the instructions for the pv_ops VT_d here:
 http://wiki.xensource.com/xenwiki/VTdHowTo

0 #> echo "11f8 8032" > /sys/bus/pci/drivers/pci-stub/new_id
0 #> echo "0000:17:00.0" > /sys/bus/pci/devices/0000:17:00.0/driver/unbind
0 #> echo "0000:17:00.0" > /sys/bus/pci/drivers/pci-stub/bind

Then, when I ran

xm pci-attach dpm 0000:17:00.0 17      ( is that right? )


the console prints:

(XEN) [VT-D]iommu.c:1289:d0 domain_context_unmap:PCIe: bdf = 17:0.0
(XEN) [VT-D]iommu.c:1175:d0 domain_context_mapping:PCIe: bdf = 17:0.0
(XEN) [VT-D]iommu.c:1289:d0 domain_context_unmap:PCIe: bdf = 17:0.0
(XEN) [VT-D]iommu.c:1175:d0 domain_context_mapping:PCIe: bdf = 17:0.0

and the domU reboots.
