I tried printing a novaclient.v1_1 server object returned by novaclient.v1_1.server.Server.interface_list() with this code:
Note: self.clients[item['tenant'] is an instance of novaclient.v1_1.client
nvlist = self.clients[item['tenant']].servers.list()
for ins in nvlist:
lst = ins.interface_list()
print type(lst[0])
print lst
This results in:
<class 'novaclient.v1_1.servers.Server'>
Traceback (most recent call last):
File "./collect.py", line 38, in <module>
points = cl.score()
File "/home/stack/Cert/mcoe/instances.py", line 38, in score
print lst[0]
File "/opt/stack/python-novaclient/novaclient/v1_1/servers.py", line 36, in __repr__
return "<Server: %s>" % self.name
File "/opt/stack/python-novaclient/novaclient/base.py", line 458, in __getattr__
raise AttributeError(k)
AttributeError: name
The issue here is that neither the novaclient.v1_1.servers.Server object nor its base.Resource parent class returned by interface_list has a name field:
[['HUMAN_ID', 'NAME_ATTR', '__class__', '__delattr__', '__dict__', '__doc__', '__eq__', '__format__', '__getattr__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_add_details', '_info', '_loaded', 'add_fixed_ip', 'add_floating_ip', 'add_security_group', 'backup', 'change_password', 'clear_password', 'confirm_resize', 'create_image', 'delete', 'diagnostics', 'evacuate', 'fixed_ips', 'force_delete', 'get', 'get_console_output', 'get_password', 'get_spice_console', 'get_vnc_console', 'human_id', 'interface_attach', 'interface_detach', 'interface_list', 'is_loaded', 'list_security_group', 'live_migrate', 'lock', 'mac_addr', 'manager', 'migrate', 'net_id', 'networks', 'pause', 'port_id', 'port_state', 'reboot', 'rebuild', 'remove_fixed_ip', 'remove_floating_ip', 'remove_security_group', 'rescue', 'reset_network', 'reset_state', 'resize', 'restore', 'resume', 'revert_resize', 'set_loaded', 'shelve', 'shelve_offload', 'start', 'stop', 'suspend', 'unlock', 'unpause', 'unrescue', 'unshelve', 'update']
Possible remedies:
- A name field could be added to base.Resource
- Another way could be used to identify the interface returned, maybe IP or MAC of the interface
- the __repr__ method could be removed entirely if deemed unnecessary
This needs more information about the version of the client and server used.
