Some typo i guess.

>From VTdHowTo:
"VT-d Device Hot-Unplug

VT-d hot-unplug refers to detaching a pass-through device from a
running HVM domain. The device may have been attached using boot-time
VT-d device pass-through or VT-d device hot-plug.

xm's pci-attach command is used to perform hot-unplug."
should be detach right?
