Hi everyone, Just wanted to give a heads up about the change that recently merged in Nova which will affect Train (and current master, for deployment projects). https://review.openstack.org/#/c/603910/ As of that change, Nova will no longer allow you to to create a VM when the root_gb of a flavor is set to 0. This is to avoid a reported security issue which we've found a while ago: https://launchpad.net/bugs/1739646 If you're using devstack, you'll probably be okay as the following change has already fixed it: https://review.openstack.org/#/c/619319/ However, deployment projects will need to make that adjustment as well as deployers need to plan accordingly (everyone is going to upgrade to Train the day we release, right?) -- Mohammed Naser — vexxhost ----------------------------------------------------- D. 514-316-8872 D. 800-910-1726 ext. 200 E. mnaser@vexxhost.com W. http://vexxhost.com
