As if we do not have enough moving parts, we are adding intentional randomness. Reproducibility is far more important than coverage - particularly for a shared system test like OST. > 117 else: > 118 return sorted(hosts, key=lambda host: host.name) > 119 raise RuntimeError('Could not find hosts that are up in DC %s' % dc_name) > > > I'm also not able to reproduce this issue locally on my server.

Then we'd have better understanding on the next failure.
