La herramienta permite guardar el estado de uno o m\u00e1s procesos y luego reanudar el trabajo 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<p>Entre las \u00e1reas de aplicaci\u00f3n de la tecnolog\u00eda CRIU se destacan la reinicializaci\u00f3n del sistema operativo sin interrumpir la continuidad de la ejecuci\u00f3n de procesos de larga duraci\u00f3n, 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), realizar actualizaciones del n\u00facleo sin reiniciar servicios, guardar peri\u00f3dicamente el estado de tareas computacionales de larga duraci\u00f3n para reanudar el trabajo en caso de un fallo, equilibrar la carga en nodos dentro de cl\u00fasteres, duplicar procesos en otra m\u00e1quina (fork en un sistema remoto) y crear instant\u00e1neas de aplicaciones de usuario en ejecuci\u00f3n para su an\u00e1lisis en otro sistema o en caso de que se necesite deshacer acciones posteriores en el programa.     <\/p>\n<p>En esta nueva versi\u00f3n:  <\/p>\n<ul>\n<li class=\"l\"> El plugin amdgpu implementa la posibilidad de paralelizar la restauraci\u00f3n del estado de procesos que utilizan GPU.\n<li class=\"l\"> Se ha a\u00f1adido la opci\u00f3n \u00ab\u2014allow-uprobes\u00bb, que permite trabajar con procesos que utilizan vma (Virtual Memory Area) al rastrear procesos a trav\u00e9s del mecanismo uprobe.\n<li class=\"l\"> En la biblioteca libcriu se ha a\u00f1adido la posibilidad de especificar un archivo de configuraci\u00f3n RPC para contenedores en tiempo de ejecuci\u00f3n que utilizan dicha biblioteca, como crun. Por ejemplo, esta posibilidad implementada puede ser \u00fatil para establecer opciones, como \u00ab\u2014tcp-established\u00bb, a trav\u00e9s del archivo \/etc\/criu\/runc.conf para Kubernetes.\n<li class=\"l\"> Se han resuelto problemas de compilaci\u00f3n en sistemas ARM64 con la biblioteca C musl.\n<li class=\"l\"> Se ha eliminado un desbordamiento entero en la funci\u00f3n pagemap_len().\n<li class=\"l\"> Se han resuelto problemas con el uso de las opciones getsockopt SO_PASSCRED y SO_PASSSEC en sistemas con el n\u00facleo Linux 6.16.        <\/ul>\n<p>Fuente: <a content=\"nofollow\"
