  # The nova-status upgrade check command has three standard return codes:
  # 0: all checks were successful
  # 1: warning: there might be some checks that require investigation, but
  #    generally will not block an automated install/upgrade; digging into
  #    warnings is useful for debugging post-install/upgrade issues
  # 2: at least one check failed and must stop the install/upgrade because
  #    something was not setup properly
