Abstract

"MODO DE PROCESSADOR PARA LIMITAR A OPERAçãO DE SOFTWARE CONVIDADO EXECUTADO EM UMA MáQUINA VIRTUAL COMPATìVEL COM UM MONITOR DE MáQUINA VIRTUAL". A presente invenção refere-se a um modo processador que é provido para software convidado. O modo processador habilitar o software convidado a operar em um nível de privilégio contemplado pelo software convidado. Quando o software convidado tenta executar uma operação restrita pelo modo processador, o modo processador é egresso para transferir controle da operação para um monitor de máquina virtual, que opera fora deste modo processador.
