It doesn't want to. As Mark said, libvirt just wants to be able to ensure a stable guest ABI, of which stable PCI addresses is one aspect. This does not imply libvirt wants to allocate the PCI addresses, just that it wants a way to keep them stable. All else being equal I'd rather libvirt wasn't in the PCI address allocation business.
