Hey, Nova guys
File "/opt/stack/python-novaclient/novaclient/v1_1/servers.py",
line 39, in __repr__
return "<Server: %s>" % self.name
File "/opt/stack/python-novaclient/novaclient/openstack/common/apiclient/base.py",
line 461, in __getattr__
self.get()
File "/opt/stack/python-novaclient/novaclient/openstack/common/apiclient/base.py",
line 479, in get
new = self.manager.get(self.id)
File "/opt/stack/python-novaclient/novaclient/v1_1/servers.py",
line 543, in get
return self._get("/servers/%s" % base.getid(server), "server")
File "/opt/stack/python-novaclient/novaclient/base.py", line 147, in _get
_resp, body = self.api.client.get(url)

in _time_request
resp, body = self.request(url, method, **kwargs)
File "/opt/stack/python-novaclient/novaclient/client.py", line 236,
in request
raise exceptions.from_response(resp, body, url, method)
NotFound: Instance could not be found (HTTP 404) (Request-ID:
req-e6208ee5-5fb3-4195-983f-9847124a9982)
Looking this trace stack, we could know that I have a *server* object, and
when called server.name, the *server* went to lazy load. That means this
*server* object doesn't
have name AttributeError from initializing. And all attributes of
*server*are from nova api response. That is the response against nova
get-server
api didn't contain name
keyword. So what case would make this happened?
The following 404 error is understandable. In that runtime, my codes are
trying to deleting a server. So during the lazy loading, the server has
been already deleted which
results that 404 error.
My question is about that "self.name". Why does such a server object miss
the "name" attribute?
