It looks like Paramiko 2.0.0 again breaks nova which currently has a requirement for 'paramiko>=1.16.0 # LGPL'.

Paramiko 2.0 got released 26 days ago with [1]. Nova put a workaround in place to work with paramiko 2.x 21 days ago [2]. After that, we bumped the version in the global requirements to 2.0 [3]. I tested it locally with commit 9d99081 (Newton master) and it works for me. I also didn't find the error message in logstash. I could reproduce this issue when I used stable/Mitaka and upgraded from the pinned version paramiko 1.16 to paramiko 2.0 manually.
All of this makes me believe that your setup could be in a weird state. I'm closing this for now. If you can reproduce it, feel free to reopen.
