In newer Xen versions, PCI passthrough works this way:
xm help enlists these commands:
pci-attach Insert a new pass-through pci device.
pci-detach Remove a domain's pass-through pci device.
pci-list List pass-through pci devices for a domain.
pci-list-assignable-devices List all the assignable pci devices
1. Enlist all PCI devices you may assign a domU
# xm pci-list-assignable-devices
2. Assign these two devices to the first domU
# xm pci-attach 1 0000:02:00.0
# xm pci-attach 1 0000:02:00.1
3. List devices assigned to first domU
# xm pci-list 1
VSlt domain bus slot func
0x06 0x0000 0x02 0x00 0x0
0x07 0x0000 0x02 0x00 0x1
"VSlt" is the "virtual slot"
