At the moment you need a nfs storage as nux wrote. Without it you are unable to use host ha.
As far as I understand you can use both ha options and host ha will start vms on another host if a host will be unavailable. But I am not 100% sure about this.

In our case, using Cloudstack + Linstor. And to clarify my understanding. Host HA migrates VMs to another Host if Cloudstack detects the physical host to be unhealthy, right? That’s all?
