Open Stack

We're migrating already since Friday jobs using the so-called
bare-trusty images to ubuntu-trusty images.

These images are used for for most of unit and functional tests, for
documentation etc. Devstack is still run on devstack-trusty nodes for
now, but will also move at a later date.

A direct benefit of this change is that bare-trusty images are only
available on Rackspace clouds, while the new ubuntu-trusty images are
available in all clouds that the CI systems use. This allows a better
load balancing for these.

We still have to convert some jobs and solve a few problems with
specific jobs before we can make a general announcement and explain
new possibilities that this change will bring projects.

For now, if jobs suddenly fail, please check - as usual - the log
files and if there is anything strange happening that always worked,
please raise it on the #openstack-infra IRC channel.

One note: We converted some names of jobs as well, so intead of
gate-REPO-tox-ENVIRONMENT we change these to
gate-REPO-tox-nodb-ENVIRONMENT if no MySQL/PostgreSQL databases are
needed and otherwise to gate-REPO-tox-db-ENVIRONMENT. As final step,
we will rename the nodb variant as default variant. Open changes are
[1] and [2].

A more detailed announcement will come once this change is done.
