The certificate is needed to secure the SSL communication. You can do
without it, adding "insecure=True" to the constructor of the API object,
but then the identity of the server could be forged and you won't notice.

That should work, but when you are doing this kind of query it is
usually better to let the server do the search. You can achieve that
using the same query language that is used in the GUI search bar. For
example, in the GUI search bar you can type "Hosts: cluster=mycluster".
With the SDK you can do the same, using the "list" method and the
"query" parameter:

  hosts = api.hosts.list(query="cluster=mycluster")
  for host in hosts:
    print(host.get_name())

You can open the "params.py" file
(/usr/lib/python2.7/site-packages/ovirtsdk/xml/params.py if you are
using the RPM packags) and look for the corrsponding class: Host,
Cluster, DataCenter etc. There you will see all the available "get_..."
methods.
