[Andrea Bolognani]

These were removed along with the outdated information on how
to regenerate the Dockerfiles contained in the repository, but
this part is still relevant.

+Coverity scan integration
+=========================
+
+This will be used only by the main repository for master branch by running
+scheduled pipeline in GitLab.
+
+The service is proved by `Coverity Scan`_ and requires that the project is
+registered there to get free coverity analysis which we already have for
+`libvirt project`_.
+
+To run the coverity job it requires two new variables:
+
+  * ``COVERITY_SCAN_PROJECT_NAME``, containing the `libvirt project`_
+    name.
+
+  * ``COVERITY_SCAN_TOKEN``, token visible to admins of `libvirt project`_
