Thank you.
I installed the package.
Now I've got this error when I paste the vnc url (which I got with nova
get-vnc-console) in firefox:
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/eventlet/wsgi.py", line 347, in handle_one_response
for data in result:
TypeError: 'NoneType' object is not iterable
and the nova-xvpvncproxy.log looks like this:
