Bug description:
  Running kilo master devstack on ubuntu 15.04. Created pci-whitelist
  and alias in local.conf and is visible in nova.conf per
  https://wiki.openstack.org/wiki/Pci_passthrough

  Added PCI alias to a nova flavor. When lauching instance with that flavor, it fails saying alias not found.
