[Bug 1392964] Re: UnicodeDecodeError

  Thread Previous • Date Previous • • Thread Next 
nova is trying to execute a command and oslo.concurrency (processutils)
is trying to look for passwords to mask them in the log and raising a
Unicode error. Is there a log line before the stacktrace saying Mount
device on dir? my hunch is something about that is unicode

** Also affects: oslo.concurrency
   Importance: Undecided
       Status: New

** Changed in: nova
       Status: New => Incomplete

  I created a instance via nova CLI.

  # nova boot --image precise --flavor 2 --nic net-
  id=f11d09a5-b3f2-41bb-9260-0b2cbc8d2568 vm03

  I installed icehouse version of opentack and ubuntu 12.04.5 LTS.
