The rngd service has nothing to do with your problem. It’s described as “Hardware RNG Entropy Gatherer Daemon” and probably fails because your DevStack runs in a VM, not on hardware.

This looks like what >I see here: https://github.com/paramiko/paramiko/issues/584 It seems to me that you have the wrong Python module gssapi installed on that server. If you don’t use Kerberos for authentication, you shouldn’t have gssapi at all. When gssapi doesn’t exist, Paramiko doesn’t even try to access gssapi.GSSException. Check if you have gssapi, and if so, remove it. Just look for a directory named *gssapi*, and do a pip uninstall on the name of that directory. Bernd.

Try a stable branch e.g. git clone ... –b stable/queens. Or just clone the master again later. Your local.conf may also be at the origin of this error. The full stack trace with a little bit of context may also be helpful (journalctl –u devstack@n-cpu). It might contain other errors or warnings that provide a clue. Also look for Nova-related errors or warnings in the stack.sh log file. Bernd.
