[Rdo-list] error when launching new instances

Hi all, I'm not so in depth with Openstack, I'm just trying launching new instances, but I'm getting this error: "The requested instance cannot be launched as you only have 0 of your quota available." It seems related to "quota" settings for "admin" user/project but I've increased all the "Defaults" . What can i check ? (nova log file are without error).
