Hi, I created a BZ with very detailed information: https://bugzilla.redhat.com/show_bug.cgi?id=1038121 tl;dr: The above mentioned OS does not start correctly if you attach a cd-rom to it, this includes submitting meta-data via Cloud-Init. The System hangs during the boot-process. I couldn't reproduce this with Ubuntu 13.10, but I have to get Ubuntu 12.04 LTS running with Cloud-Init. I did not find any hint in the Ubuntu log files to the causes of behaviour. You find most of the relevant log files in the BZ. The System boots fine if you eject the cd via webadmin. It seems not to get removed automatically when you shutdown the machine. Did anybody else run into this issue? Any help would be appreciated. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
