All,

I would like to start discussion on a new feature - Host HA for CloudStack.

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 HA provider 
implementation specific for hypervisor that can use additional mechanism such 
as OOBM (ipmi based power management) to reliably investigate, recover and 
fence a host. This feature can handle scenarios associated with server crash 
issues and reliable fencing of hosts and HA of VM. The first version will have 
HA provider implementation for KVM (and for simulator to test the framework 
implementation, and write marvin tests that can validate the feature on Travis 
and others).


Please have a look at the FS here:

Looking forward to your comments and questions.


Regards.
