OpenStack Summit in Barcelona is now officially over. The Summit happened between October 25 and 28th in Barcelona, Spain. This being my first Summit, I was excited about what to see and who I would meet during the conference 4 days. The fact that I had the chance to deliver two presentations alongside my team members. Since this was _the_ OpenStack Summit, we could not go on without, well having OpenStack, so we brought one own.
After chasing this information too often, I’ve decided to give a break to my brain and compile a list of the most common OpenStack Images (at least for my day-to-day activities). Without further ado, here’s the list: Distribution Default User Ubuntu 14.04 Trusty ubuntu CentOS 6⁄7 centos Red Hat Enterprise Linux 6⁄7 cloud-user CirrOS cirros Debian admin A complete and up to date list can be found at the OpenStack site.
