Extending the current functionality of KVM Host HA for the StorPool storage plugin and the option for easy integration for the rest of the storage plugins to support Host HA This extension works like the current NFS storage implementation. It allows it to be used simultaneously with NFS and StorPool storage or only with StorPool primary storage. If it is used with different primary storages like NFS and StorPool, and one of the health checks fails for storage, there is an option to report the failure to the management with the global config kvm.ha.fence.on.storage.heartbeat.failure. By default this option is disabled when enabled the Host HA service will continue with the checks on the host and eventually will fence the host
