Solve the following python programming problem given the following code:
def _setup_fakelibvirt(self) : 
    self.flags (instances_path = self.useFixture (fixtures.TempDir ()).path) 
    if ('libvirt' in sys.modules) : 
        self.saved_libvirt = sys.modules ['libvirt'] 
else : 
        self.saved_libvirt = None 
import nova.tests.unit.virt.libvirt.fake_imagebackend as fake_imagebackend 
    import nova.tests.unit.virt.libvirt.fake_libvirt_utils as fake_libvirt_utils 
    import nova.tests.unit.virt.libvirt.fakelibvirt as fakelibvirt 
    import nova.tests.unit.virt.libvirt.fake_os_brick_connector as fake_os_brick_connector 
    sys.modules ['libvirt'] = fakelibvirt 
    import nova.virt.libvirt.driver 
    import nova.virt.libvirt.firewall 
    import nova.virt.libvirt.host 
    self.useFixture (fixtures.MonkeyPatch ('nova.virt.libvirt.driver.imagebackend', fake_imagebackend)) 
    self.useFixture (fixtures.MonkeyPatch ('nova.virt.libvirt.driver.libvirt', fakelibvirt)) 
    self.useFixture (fixtures.MonkeyPatch ('nova.virt.libvirt.driver.libvirt_utils', fake_libvirt_utils)) 
    self.useFixture (fixtures.MonkeyPatch ('nova.virt.libvirt.host.libvirt', fakelibvirt)) 
    self.useFixture (fixtures.MonkeyPatch ('nova.virt.libvirt.imagebackend.libvirt_utils', fake_libvirt_utils)) 
    self.useFixture (fixtures.MonkeyPatch ('nova.virt.libvirt.firewall.libvirt', fakelibvirt)) 
    self.useFixture (fixtures.MonkeyPatch ('nova.virt.libvirt.driver.connector', fake_os_brick_connector)) 
    fakelibvirt.disable_event_thread (self) 
    self.flags (rescue_image_id = '2', rescue_kernel_id = '3', rescue_ramdisk_id = None, snapshots_directory = './', sysinfo_serial = 'none', group = 'libvirt') 
    def fake_extend(image, size) : 
        pass 
def fake_migrateToURI(* a) : 
        pass 
def fake_make_drive(_self, _path) : 
        pass 
def fake_get_instance_disk_info(_self, instance, xml = None, block_device_info = None) : 
        return '[]' 
def fake_delete_instance_files(_self, _instance) : 
        pass 
def fake_wait() : 
        pass 
def fake_detach_device_with_retry(_self,...

    
    

    Fix the buggy line: self.stubs.Set (nova.virt.libvirt.guest.Guest, 'detach_device_with_retry', fake_make_drive)
