This hook will perform the onevm delete --recreate action on the VMs of the failed host. To avoid false positives because of network connectivity issues, use the -p flag of the hook. The delete-recreate action will create a new VM from the original template. This means that the VM will have a new ID, IP, and clean disks. We are working on a new mechanism for hosts with shared storage, to "migrate" the failed VM to a new host keeping the current IPs, disk state, etc. Regards [1] http://docs.opennebula.org/4.8/advanced_administration/high_availability/ftguide.html -- Carlos Martín, MSc Project Engineer OpenNebula - Flexible Enterprise Cloud Made Simple www.OpenNebula.org <http://www.opennebula.org/> | cmar...@opennebula.org | @OpenNebula <http://twitter.com/opennebula> <cmar...@opennebula.org>
