    @koushik-das I see that main issue is that this is being confused as VM HA framework.
Will like to again add that this framework is not for VM-HA but for host HA. With this implementation
of OOBM framework, Cloudstack is now in the position to control and HA a host. These developments
helped us in putting together a Host HA framework. Only that while designing and coding we
tried to keep it flexible so that later other entities that can be HAed can be added to the
framework.

> CloudStack lacks a way to reliably fence a host, the idea of the host-ha feature is to
provide a general purpose HA framework and implementation specific for hypervisor that can
use additional mechanism such as OOBM (ipmi based power management) to reliably investigate,
recover and fencing a host. This feature can handle scenarios associated with server crash
issues and reliable fencing of hosts and HA of VM.
