La l\u00f3gica actual actualiza el modo de tabla de p\u00e1ginas de E/S para el dominio antes de llamar a la l\u00f3gica para liberar la memoria utilizada para la tabla de p\u00e1ginas. Esto da como resultado una p\u00e9rdida de memoria en la tabla de p\u00e1ginas de IOMMU y se puede observar al iniciar VM con dispositivos de paso. Se soluciona liberando la memoria utilizada para la tabla de p\u00e1ginas antes de actualizar el modo."
