Those docs are useless, since they are not reflecting significant step -
creating custom Trove images. You need to create image with Trove installed
in it, create upstart scriptto lauch Trove-guestagent with appropriate
configuration files that comes to the compute instance through file
injection.
Vanilla images are good, but they don't have Trove in it at all.

Here are some useful steps:
1. Create custom image with trove code in it (upstart scripts, etc).
2. Register datastore and associate given image with appropriate
datastore/version.

FYI, Trove is not fully integrated with devstack, so, personally i'd
suggest to use https://github.com/openstack/trove-integration  simple (3
clicks) Trove + DevStack deployment.

Correct.

Correct since Trove-guest agent service wasn't able to  report about its
state.

Correct. You cannot modify/use instances that are remaining in BUILD state.
