Here is how to create a cloud-init disk image and OS disk image suitable for configuring into a libvirt domain file.

In my case I am naming my domain (a.k.a. virtual machine or VM) xenial with a static IP address of 192.168.0.101. The filenames "network-config" and "user-data" files are arbitrary, so they can be named with a prefix for the domain, etc.

First, get the cloud image and convert into QCOW2 format:

qemu-img convert -O qcow2 xenial-server-cloudimg-amd64-disk1.img xenial-server-cloudimg-amd64-disk1.qcow2

There seems to be a typo in the Spring Data JDBC section for @Query since the following custom repository query with the placeholder reference :#{topic.id}:

    @Query("SELECT * FROM activity" +
        " WHERE topic = :#{topic.id}" +
        "  AND lower(name) LIKE lower(:namePattern)" +
        " ORDER BY name")
    List<Activity> findAllNameLikeCaseInsensitive(Topic topic, String namePattern);
