When you say instances, are you actually talking about the VM's? Of course they will be booted from volumes in ceph, but I am talking about the Compute Nodes, the actual hypervisors. I of course would have to use pxe for that. No idea if there was a way for me to use ceph that way though. Yes, puppet is a great tool for automating tasks, etc, but that obviously takes a lot of time to setup manually and I honestly have very little puppet experience so far. Its something I need to keep in mind though. Thanks for the response.
