Se ha publicado la versi\u00f3n 4.0 de la herramienta CRIU (Checkpoint and Restore In Userspace), dise\u00f1ada para guardar y restaurar procesos en el espacio de usuario. Esta herramienta permite guardar el estado de uno o varios procesos y luego reanudar la operaci\u00f3n desde la posici\u00f3n guardada, incluso despu\u00e9s de reiniciar el sistema o en otro servidor sin interrumpir las conexiones de red establecidas. El c\u00f3digo del proyecto est\u00e1 escrito en C y se distribuye bajo la licencia GPLv2. CRIU se utiliza en sistemas de gesti\u00f3n de contenedores como OpenVZ, LXC\/LXD y Docker. Los cambios necesarios para el funcionamiento de CRIU est\u00e1n incluidos en el n\u00facleo principal de Linux. <\/p>\n
Entre las aplicaciones de la tecnolog\u00eda CRIU se destaca la capacidad de reiniciar el sistema operativo sin interrumpir la ejecuci\u00f3n de procesos que llevan mucho tiempo, la migraci\u00f3n en vivo de contenedores aislados, la aceleraci\u00f3n del inicio de procesos lentos (se puede comenzar a trabajar desde un estado guardado despu\u00e9s de la inicializaci\u00f3n), la realizaci\u00f3n de actualizaciones del n\u00facleo sin reiniciar los servicios, el guardado peri\u00f3dico del estado de tareas computacionales de larga duraci\u00f3n para reanudar el trabajo en caso de fallo, el balanceo de carga en nodos en cl\u00fasteres, la duplicaci\u00f3n de procesos en otra m\u00e1quina (fork en un sistema remoto), la creaci\u00f3n de instant\u00e1neas de aplicaciones de usuario durante su ejecuci\u00f3n para su an\u00e1lisis en otro sistema o en caso de que sea necesario deshacer acciones posteriores en el programa. <\/p>\n
En esta nueva versi\u00f3n: <\/p>\n
