Hi Vibol, I do not get you question 100%. What do you mean by unplanned hypervisor downtime? Do you mean that a hypervisor is crashing and goes down? CS has tools to restart VMs that should not be down. But you will have a downtime for VMs between crash of hypervisor and restarting the VM on another host. So we are talking about disaster recovery here. If you need real high availability you need to do this on application level for example 2 webserver behind a load balancer.

But after spending a week read and searching for more information. I found out that unplanned downtime for a hypervisor can cause a vm inside to go offline. In general, Is there a way to prevent and instants offline cause by the unplanned hypervisor downtime ? or is there any auto migration available for Apache Cloustack?
