CLOUDSTACK-9782: Host HA and KVM HA provider Host-HA offers investigation, fencing and recovery mechanisms for host that for any reason are malfunctioning. It uses Activity and Health checks to determine current host state based on which it may degrade a host or try to recover it. On failing to recover it, it may try to fence the host. The core feature is implemented in a hypervisor agnostic way, with two separate implementations of the driver/provider for Simulator and KVM hypervisors. The framework also allows for implementation of other hypervisor specific provider implementation in future. The Host-HA provider implementation for KVM hypervisor uses the out-of-band management sub-system to issue IPMI calls to reset (recover) or poweroff (fence) a host. The Host-HA provider implementation for Simulator provides a means of testing and validating the core framework implementation.
