Solve the following python programming problem given the following code:
@ mock.patch.object (fakelibvirt.Connection, 'numOfDomains') 
@ mock.patch.object (fakelibvirt.Connection, 'listDefinedDomains') 
@ mock.patch.object (fakelibvirt.Connection, 'listDomainsID') 
@ mock.patch.object (host.Host, '_get_domain_by_name') 
@ mock.patch.object (host.Host, '_get_domain_by_id')

    vm1 = FakeVirtDomain (id = 3, name = 'instance00000001') 
    vm2 = FakeVirtDomain (id = 17, name = 'instance00000002') 
    vm3 = FakeVirtDomain (name = 'instance00000003') 
    vm4 = FakeVirtDomain (name = 'instance00000004') 
    vms = [vm1, vm2, fake_get_domain_by_name, vm4] 
    def fake_get_domain_by_id(id) : 
        for vm in vms :

                return vm 
raise exception.InstanceNotFound (instance_id = id)

        for vm in vms : 
            if (vm.name () == name) : 
                return vm 
raise exception.InstanceNotFound (instance_id = name) 
def fake_list_ids() : 
        return [vm1.ID (), vm2.ID (), 666]

        return [vm1.name (), vm3.name (), vm4.name (), 'fishfood']

    mock_get_name.side_effect = fake_get_domain_by_name 
    mock_list_ids.side_effect = fake_list_ids 
    mock_list_names.side_effect = fake_list_names 
    mock_num_ids.return_value = 2 
    doms = self.host._list_instance_domains_slow () 
    mock_list_ids.assert_called_once_with ()

    self.assertEqual (len (doms), 2) 
    self.assertEqual (doms [0].name (), vm1.name ()) 
    self.assertEqual (doms [1].name (), vm2.name ()) 
    doms = self.host._list_instance_domains_slow (only_running = False) 
    mock_list_ids.assert_called_once_with () 
   ...

    
    

    Fix the buggy line: vms = [vm1, vm2, fake_get_domain_by_name, vm4]

#Here is Python code to fix the buggy line: vms = [vm1, vm2, fake_get_domain_by_name, vm4]
.

vms = [vm1, vm2, vm3, vm4]
