Hi Rohan, According to the manual, Cloudstack doesn't have this feature:
http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.11/reliability.html HA-Enabled Virtual Machines<http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.11/reliability.html#ha-enabled-virtual-machines> The user can specify a virtual machine as HA-enabled. By default, all virtual router VMs and Elastic Load Balancing VMs are automatically configured as HA-enabled. When an HA-enabled VM crashes, CloudStack detects the crash and restarts the VM automatically within the same Availability Zone. HA is never performed across different Availability Zones. CloudStack has a conservative policy towards restarting VMs and ensures that there will never be two instances of the same VM running at the same time. The Management Server attempts to start the VM on another Host in the same cluster. HA features work with iSCSI or NFS primary storage. HA with local storage is not supported.

Providing zone HA feature. - Higher availability of the services: users can deploy services across Availability Zones and even if one of the Availability Zones goes down the services are still available to the end-user through VMs deployed in other zones. Please guide.......... Thanks and regards Rohan [email protected] www.shapeblue.com Amadeus House, Floral Street, London WC2E 9DPUK @shapeblue
