Hi, First, congrats to the centos community on the recent development. Reading the call for SIG, there is definitely interest from CloudStack to participate and create a ClouStack centOS variant for both instances and head/hypervisor nodes. Our default image template is already a centos template and our best quick start guide is based on CentOS. We also have a community run yum repo for all our packages. I see interest to create a Cloud Image for CloudStack clouds as well as creating variants for our management server and our hypervisor setup. I will be at the Dojo on January 31st and would be happy to discuss further. Cheers, -Sebastien Apache CloudStack PMC member
