Trove Guest Agent Not starting

Question

I am trying to install Openstack Trove guestagent, however, it's unable to start and giving me the following error (as observed by the logs):

2015-04-17 17:54:45.181 3237 CRITICAL root [-] RuntimeError: Manager class not registered for datastore manager None 
2015-04-17 17:54:45.181 3237 TRACE root Traceback (most recent call last):

2015-04-17 17:54:45.181 3237 TRACE root RuntimeError: Manager class not registered for datastore manager None

I am unable to understand what's the issue. Any guidance would be very much welcome.

Answer 1

After reading Trove (test code), I've found this line:

MANAGER = CONF.datastore_manager if CONF.datastore_manager else 'mysql'

Try add the following configuration line in your trove-guestagent.conf:

datastore_manager = mysql

and restart guest agent service.
