As of 4.11 CloudStack has an enhancement for KVM HA. Instead of relying on shell script and specific primary store - we will check the write time stamp on the disks for all VMs that are known to reside on hypervisor.
All VM disks/files must not update the write timestamp for an extended amount of time(configurable) before a specifc action is taken (configurable). Even If a single vm disk will have a write timestamp and all other don’t - we will not power off the host.
You can read more about KVM HA on cloudstack homepage, there is also a video talk by Rohit Yadav that explains it in great details.
