I was thinking of something simpler, adding the dictionary local to 
do_test_x86_64_machine().

  def do_test_x86_64_machine(self, test_type):
    d = {
      'pvh_disabled': {
         'url': 'https://archives.fedoraproject.org/'
                'pub/archive/fedora/linux/releases/29/Everything/'
                'x86_64/os/images/pxeboot/vmlinuz',
          'hash': '23bebd2680757891cf7adedb033532163a792495'
      },
      'pvh_enabled': {...}
    }
    ...

  def test_x86_64_pc_pvh(self):
         """
         :avocado: tags=machine:pc
         """
         self.do_test_x86_64_machine('pvh_enabled')
