Hi Vibol, CS can only bring up VMs in the same cluster, because only this cluster has access to primary storage of the cluster where VM data is on. So if all hosts of one cluster are gone there is no way for CS to bring up these VMs.

And i don't have any running instant yet because i plan to setup advance network with openvswitch for my testing environment. as you mention, Did the cloudstack will automatic failover or restart the vmware to another hypervisor if we enable an instant HA ?
