Morning Leander,

The key file is what's in your nova api-paste.ini file - it's what is defining the WSGI pipeline that loads up the various bits that set context. What version of Nova and Keystone are you running?

I rather suspect you might have updated your code without also getting the updates into your api-paste.ini file.
