Add support for arm64 images

Clark Laughlin · Andrew McDermott · commit fcc3f6ee986c · 2015-04-09T08:55:56.000Z
This patch enables proper support for arm64 images by disabling VNC support
and adding several properties to the image in glance that are necessary to
boot correctly:
  hw_cdrom_bus=virtio
  hw_machine_type=virt
  os_command_line='console=ttyAMA0'
