you are confusing IO/IRQ resources with physical bus IDs. When you export a PCI device, you export the entire card that is plugged into a PCI address, which for the most part is static unless you add or remove cards. The IO/IRQ resources that card requires go with it when it is exported. Most parallel ports are ISA based, but you could pick up a PCI parallel port card and export that.

I see instructions on how to hide a pci i/o address and let a guest have access to it. How about plug and play devices? I'd like to pass my parallel port to a guest, but it's detected by plug and play. Must I disable pnp in my bios or is there another way.
