I tried to create a instance with trove which is in 'BUILD' state forever.The trove-guestagent fails with an error:

2015-03-03 14:35:53.755 5268 CRITICAL root [-] Manager class not registered for datastore manager None

The trove-guestagent conf file:

rabbit_host = host_ip rabbit_port = 5672 rabbit_password = guest

nova_proxy_admin_user = admin nova_proxy_admin_pass = admin_pass nova_proxy_admin_tenant_name = services trove_auth_url = http://host_ip:5000/v2.0 datastore_registry_ext = mysql:trove.guestagent.datastore.mysql.manager.Manager datastore_manager = trove.guestagent

With the datastore_manager set to some value the error is: 2015-03-03 14:35:53.755 5268 CRITICAL root [-] Manager class not registered for datastore manager trove.guestagent

Could anyone please let me know what should be the datastore_manager value to fix this issue.

Thanks in advance.
