Hello Bryan,
your understanding is correct to my knowledge and experience.
Host HA is restarting all affected VMs on a still running Host in case of a
Host failure.
VM HA is restarting the VM in case the VM fails / is not running even though it
should.
VM HA will even (re)-start the VM in case
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.
Regards,
Swen
