With XenAPI you can set the VM.other-config:pci key to a comma separated
list of "<bus>/<bdf>" where bus should always be 0 and <bdf> is the
bus-device-function as seen in domain 0. For example to pass device
0000:07:10.0 through to a guest try:
xe vm-param-set uuid=<uuid> other-config:pci=0000:07:10.0
You may need to manually load the pciback module first.
