I've passed the session object from another class (using Cherrypy cookies) and rebuilt the Nova instance in this class to list the servers. The rebuilt Nova instance works however when I try and create a list of servers, I have an attribute error. There's very little (I found nothing remotely like this issue) out on the internet about this sort of issue. How do I solve this issue? :)
Code:
import cherrypy
import xmlrpclib
import xml.etree.ElementTree as ET
from keystoneauth1 import loading
from keystoneauth1 import session
import novaclient.client as client
from socket import gethostbyaddr
nova = client.Client("2.1", session=cherrypy.request.cookie.get('sessCookie').value)
serverList = nova.servers.list()
print serverList

The value of the session keyword is supposed to be a Keystone session object, but you're passing in a string.
You can read more about working with Keystone sessions here.
