So to gather more pointers I tried a Trusty host and Utopic KVM guests. Either manually created (with virt-manager and not involving cloud-init then) and also using uvtool which is at least using a vdb for cloud-init data (in some way, though the image is a ro iso). Both ways the jbd2 process goes away after unmount.
