This looks hypervisor/kernel related. Some observations:
The cloud-init.log in the collect-logs shows cloud-init running twice. The first time, run-time is expected, approx 17s of cloud-init time, the second boot took much longer, but the bulk if the time is in udev 2019-06-20 18:09:18,951 - util.py[DEBUG]: Running command ['udevadm', 'settle'] with allowed return codes [0] (shell=False, capture=True) 2019-06-20 18:10:48,209 - util.py[DEBUG]: Waiting for udev events to settle took 89.258 seconds Some kernel logs around this time show some strangeness: Jun 20 18:09:18.252780 cnewcomer-1561053730 systemd[1]: Reached target System Time Synchronized.
