When trying to instanciate a MySQL database instance with Trove, the guest agent fails to get the database status leaving the instance in an error state.

Here's the trove-guestagent.log:

I've have tried the following things:

• I checked the init-script for the guest agent. The start-stop-deamon is correctly invoked with trove as chuid parameter
• I have added the user trove to the sudo users, which does not change the result
• Since I suspected the error might not be an issue with sudo, but with the mysqladmin command wanting to prompt for a password, I supplied username and password in the releavant line of the service_base.py, I still got the same result

I'm running an Openstack Liberty install on Ubuntu 14.04.

Can anyone point me in the right direction to what is wrong here? If you any additional helpful info, let me know.
