Comment 6 for bug 1572826

It looks like device name is not used in the match for pci device specifications:

From PciDeviceSpec class in nova.pci.devspec:

    def match(self, dev_dict):
        conditions = [
            self.vendor_id in (ANY, dev_dict['vendor_id']),
            self.product_id in (ANY, dev_dict['product_id']),
            self.address.match(dev_dict['address'],
                dev_dict.get('parent_addr'))
            ]
        return all(conditions)
