Now... from what Laine was saying it sounds like more of the differences between PCI-E placement and PCI placement may be implemented by libvirt than qemu than I realized. So possibly we do want to make the bus be PCI-E on the qemu side, but have libvirt use the vanilla-PCI placement guidelines rather than PCI-E for pseries.
Basically the special casing I was mentioning earlier.
That looks complicated.. I wish I would no more about the pseries PCIe stuff, does any one know where I can get the info ? (besides 'google it'...)
