             Summary: Unable to list nodes with Libvirt provider on Python 3
                 Key: LIBCLOUD-858
                 URL: https://issues.apache.org/jira/browse/LIBCLOUD-858
             Project: Libcloud
          Issue Type: Bug
          Components: Compute
         Environment: Ubuntu 16.04.1 LTS
Python 3.5.2
Libcloud installed from 1a836148250ebf852a7f28e4d93007417ee7639d

            Reporter: Fahri Cihan Demirci


Using the {{list_nodes}} methods of the Libvirt provider driver results in an error when using Python 3. A simple script to trigger this is as follows:

{code}
from libcloud.compute.providers import get_driver
from libcloud.compute.types import Provider

cls = get_driver(Provider.LIBVIRT)
driver = cls('qemu:///system')
nodes = driver.list_nodes()
{code}

It results in the following error:
{code}
