Guys, I just did an "apt-get update ; apt-get dist-upgrade" on my IceHouse, powered by Ubuntu 14.04.1.
The cloud was working smoothly for months, and right after this upgrade, it becomes impossible to create a Instance. It doesn't leave the "Build" state. OpenStack needs to handle upgrades in a more consistent way. It is a pain to do a single upgrade, every time I see a new version, the fear comes. Can you guys imagine how hard will be to upgrade from IceHouse to Juno?! I don't know a single person on this Earth that is capable of doing this job. I'll try, I'll do it but, after days of work, where an "cloud-archive:juno ; apt-get update ; apt-get dist-upgrade" SHOULD be enough, but I hardly think that it will be that easy, and I have a small cloud (about 20 nodes / 200 instances). I'm using OpenStack since Essex and I never saw an upgrade that worked out-of-the-box, without the need to enable debug and losing hours trying to figure out what's going on after a very small upgrade. Under admin, I can see all services enabled, all compute services up, all network agents up but, I'm not able to create instances anymore. I just double checked all configuration files, dpkg did not touch the files during the "apt-get dist-upgrade". All nodes are already upgraded, controller, glance, network and computes... What can I do?! Thanks in advance! Best, Thiago
