We don't need to list the volumes twice, not only it seems inefficient, the number of volumes can change in the meantime, leading to possible invalid memory access. Possibly an APPEND_ELEMENT macro similar to what we have in libvirt, so that we can test it separately in test_util.c.

This would leak ret.
