We are working on a patch that would enable such capability within OpenStack Nova. It is a bit more complex than what you suggested. In a nutshell, one would need to do the following: - re-create the VM on the destination host - re-attach volumes/IPs - update DB - make sure that if/when the original host recovers, it does not cause corruption of the instance file on shared storage (e.g., by removing the corresponding VM from the original host on startup)
