Problema con VT-x y Extended Page Tables en Intel Core i7-1255U

JNzz — Wed, 19 Feb 2025 18:45:53 GMT

Hola,

Actualmente tengo Windows 11 Home y he experimentado problemas con la virtualización. Al investigar, noté que el problema podría estar relacionado con VT-x, ya que no parece estar habilitado en mi sistema.

Descargué la herramienta Intel® Processor Identification Utility - Windows Version para verificar si mi procesador cuenta con esta característica. Sin embargo, al ejecutarla, obtuve el siguiente resultado:

Cuando descargo el resultado me aparece así:

Intel® virtualization technology: Yes
Intel® vt-x with extended page tables: No

Según las especificaciones del procesador Intel Core i7-1255U, debería ser compatible con VT-x y EPT. Sin embargo, no he encontrado ninguna opción en la BIOS para activarlo, y ya tengo instalada la versión más reciente del firmware.

Especificaciones Procesador Intel i71255u

Agradecería su ayuda para entender por qué VT-x con EPT no me aparece habilitado y qué pasos puedo seguir para solucionarlo.

¡Gracias de antemano!

Hi JNzz,

After further review, you are indeed correct that your processor supports Intel® VT-x with Extended Page Tables (EPT), as indicated in the public product specifications. The availability of this feature may vary depending on how your system was designed and manufactured, as it can be enabled or disabled by the manufacturer. To assist you further, please follow these steps:

Could you describe the specific virtualization issue you are experiencing?
Are you using a laptop or a mini-PC? Please provide the make and model.
