I've managed to create a fairly well working packstack-answer file, that I used for liberty installations, with a 4-multi-node setup, eventually handling nested kvm, live-migration, LBAAS, etc, so I am quite happy with that.
Now, my aim is Identity v3. From the packstack answer-file, it seems supported, but I cant get it to work. I couldnt get it to work with liberty, and now testing with Mitaka, it still doesnt work, failing on:
ERROR : Error appeared during Puppet run: 10.9.24.100_cinder.pp
Error: Could not prefetch cinder_type provider 'openstack': Execution of '/usr/bin/openstack volume type list --quiet --format csv --long' returned 1: Expecting to find domain in project - the server could not comply with the request since it is either malformed or otherwise incorrect. The client is assumed to be in error. (HTTP 400) (Request-ID: req-d8cccfb9-c060-4cdd-867d-603bf70ebf24)
I think this is also the same error I got, during my liberty tests.
