docs: Reads an OVF file into the appliance object.
          
          This method succeeds if the OVF is syntactically valid and, by itself, without errors. The
          mere fact that this method returns successfully does not mean that VirtualBox supports all
          features requested by the appliance; this can only be examined after a call to :py:func:`interpret` .
  
          in file_p of type str
              Name of appliance file to open (either with an .ovf or .ova extension, depending
              on whether the appliance is distributed as a set of files or as a single file, respectively).
  
          return progress of type :class:`IProgress`
              Progress object to track the operation completion.
