A minimal implementation of the Viridian (Hyper-V) guest interface. The only enlightenments advertised and supported are vAPIC MSRs and long-spin-wait notifications. The set of enlightenments can easily be extended in future, as they are found to provide a performance win, and configured via an extended HVM_PARAM_VIRIDIAN hvm parameter.
