Bug Fixes

* Since Libvirt v.1.12.0 and the introduction of the libvirt issue ,
  there is a fact that if we set cache mode whose write semantic is
  not O_DIRECT (i.e. "unsafe", "writeback" or "writethrough"), there
  will be a problem with the volume drivers (i.e.
  LibvirtISCSIVolumeDriver, LibvirtNFSVolumeDriver and so on), which
  designate native io explicitly.

  When the driver_cache (default is none) has been configured as
  neither "none" nor "directsync", the libvirt driver will ensure the
  driver_io to be "threads" to avoid an instance spawning failure.

   (https://bugzilla.redhat.com/show_bug.cgi?id=1086704)

* Addressed an issue that prevented instances using multiqueue
  feature from being created successfully when their vif_type is TAP.
