Title:
  NoneType Error was raised when booting a dedicated cpu instance on
  libvirt1.2.2

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Booting a dedicated cpu instance is failed in libvirt 1.2.2.
  I think if the libvirt version is not enough, just ignore the memnodes parameter instead of throwing NoneType error.
