The qcow2 filesize looks unreasonably large compared to the xz compressed version. Zero-filling and qcow2-compressing the image reduced its size to ~350MB.
adding in a dd bs=4096 if=/dev/zero of=/var/tmp/zeros thing... but how wildely accepted is the qcow2c format ? I recall feedback from people saying that those were causing issues in some places, and most folks just wanted qcow2
cloud-init debug messages don't show up on the console and are also not logged in /var/log/cloud-init.log. I don't claim I understand cloud-init's logging crazyness but there's some unfortunate interaction with systemd. I *think* the problem is that systemd swallows console messages from legacy services and only writes them to the journal but not the console. In fact, no output from any of the other legacy services appear on the console which could help with debugging boot issues. Setting "ForwardToConsole=yes" in /etc/systemd/journald.conf 'fixes' the issues.
will experiment.
Other than that: Ship it!
Depending on how things go - I will move to signing the cloud-init rpms, releasing them, and then doing another build on Friday AM UTC.
