A user VM can be associated with a SSH key pair while deploying that VM. A user can SSH into the VM using the SSH private Key. But there should be a provision to reset that SSH key pair corresponding to that VM, i.e., to associate a new SSH key pair to the VM. This feature aims to reset the SSH key corresponding to the VM. Please find the functional spec here at the link https://cwiki.apache.org/confluence/display/CLOUDSTACK/Reset+SSH+key+Functional+Spec
Please review and provide your feedback on this feature. Thank you, Harikrishna Pantala
