Hello Digmer, We are working on a similer project, only: EL6 / pcmk+cman (for dlm and fenced) No rgmanager since we will be using pacemaker KVM Could you kindly share some whitepapers that you have been using for your setup? Documentation for things like live migration, fenching the VMs etc..? PLEASE! Thanks in Advance, Nick.
