Description
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.
