  ceilometer.pp
    Error: Could not set groups on user[ceilometer]:
      Execution of '/usr/sbin/usermod -G ceilometer,nobody,nova ceilometer'
        returned 6: usermod: group 'nova' does not exist

There is a candidate upstream fix here:
  https://github.com/stackforge/puppet-ceilometer/commit/d064997c
Though I'm not 100% sure if it deals with the case where
ceilometer happens to be installed before nova on a particular host.

Comment 2 Lars Kellogg-Stedman 2015-03-20 16:16:45 UTC 
The original problem was caused by installing Ceilometer on a standalone host using packstack.  This configuration is no longer available with recent versions of packstack.

The problem with the ceilometer::agent::compute manifest still exists, but that needs to be solved upstream.  The ceilometer::agent:polling manifest, which seems to deprecate ceilometer::agent::compute, has a boolean (compute_namespace) that can be set to avoid this problem.
