El c\u00f3digo del hipervisor est\u00e1 basado en un hipervisor ligero desarrollado por Intel para dispositivos embebidos y <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/projectacrn\/acrn-hypervisor\">se distribuye<\/a><\/noindex> bajo licencia BSD.<\/p>\n<p>El hipervisor est\u00e1 dise\u00f1ado para cumplir con tareas de tiempo real y ser adecuado para sistemas cr\u00edticos, funcionando en hardware con recursos limitados. El proyecto busca ocupar un nicho entre los hipervisores utilizados en sistemas en la nube y centros de datos, y los hipervisores para sistemas industriales con estricta separaci\u00f3n de recursos. Como ejemplo de uso de ACRN se citan m\u00f3dulos de control electr\u00f3nico, paneles de instrumentos y sistemas de informaci\u00f3n en autom\u00f3viles, pero el hipervisor tambi\u00e9n es apto para dispositivos IoT de consumo y otras aplicaciones embebidas. <\/p>\n<p>ACRN ofrece un m\u00ednimo de sobrecarga y se compone de solo 25,000 l\u00edneas de c\u00f3digo (para comparaci\u00f3n, los hipervisores utilizados en sistemas en la nube cuentan con alrededor de 150,000 l\u00edneas de c\u00f3digo). A pesar de esto, ACRN garantiza bajas latencias (low latency) y una respuesta adecuada al interactuar con el hardware. Soporta la virtualizaci\u00f3n de recursos de CPU, entrada\/salida, subsistema de red, as\u00ed como operaciones de gr\u00e1ficos y sonido. Se proporciona un conjunto de mediadores de entrada\/salida para el acceso conjunto a recursos comunes para todas las VM.<\/p>\n<p>ACRN se clasifica como un hipervisor de tipo 1 (ejecutado directamente sobre el hardware) y permite ejecutar m\u00faltiples sistemas invitados simult\u00e1neamente, en los que pueden correr distribuciones de Linux, RTOS, Android y otros sistemas operativos. El proyecto consta de dos componentes principales: <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/projectacrn\/acrn-hypervisor\">hipervisor<\/a><\/noindex> y su correspondiente <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/projectacrn\/acrn-devicemodel\">modelo de dispositivos<\/a><\/noindex> con un rico conjunto de mediadores de entrada\/salida que gestionan el acceso compartido a los dispositivos entre los sistemas invitados. La gesti\u00f3n del hipervisor se realiza desde un sistema operativo de servicio que act\u00faa como sistema host y contiene componentes para traducir las solicitudes de otros sistemas invitados al hardware.<\/p>\n<p><center><noindex><a rel=\"nofollow\" href=\"https:\/\/projectacrn.org\/wp-content\/uploads\/sites\/59\/2019\/08\/PictureForR1_2-768x396.png\"><img decoding=\"async\" alt=\"Lanzamiento del hipervisor para dispositivos integrados ACRN 1.2, desarrollado en la Linux Foundation\" src=\"\/wp-content\/uploads\/2019\/09\/47d07b7e0eb35d87b226128c5afe872b.png\" style=\"display:block;margin: 0 auto;\" \/><\/a><\/noindex><\/center><\/p>\n<p>Principales <noindex><a rel=\"nofollow\" href=\"https:\/\/projectacrn.github.io\/latest\/release_notes\/release_notes_1.2.html\">cambios<\/a><\/noindex> en ACRN 1.2:<\/p>\n<ul>\n<li class=\"l\"> Posibilidad de utilizar firmwares <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/tianocore\/tianocore.github.io\/wiki\/OVMF\">Tianocore\/OVMF<\/a><\/noindex> como un cargador virtual para el sistema operativo de servicio (sistema host), capaz de ejecutar Clearlinux, VxWorks y Windows.
