Se recomienda un sistema con 16 GB de RAM (m\u00ednimo 6 GB) y una CPU de 64 bits de Intel o AMD que soporte tecnolog\u00edas VT-x con EPT\/AMD-v con RVI y VT-d o IOMMU de AMD, siendo deseable contar con una GPU Intel (las GPU de NVIDIA y AMD no han sido suficientemente probadas). El tama\u00f1o de la imagen de instalaci\u00f3n es de 8 GB (x86_64).    <\/p>\n<p>Las aplicaciones en Qubes se dividen en clases seg\u00fan la importancia de los datos procesados y las tareas a resolver. Cada clase de aplicaciones (por ejemplo, trabajo, entretenimiento, operaciones bancarias), as\u00ed como los servicios del sistema (subsistema de red, cortafuegos, gesti\u00f3n de almacenamiento, pila USB, etc.), funcionan en m\u00e1quinas virtuales separadas que se ejecutan utilizando el hipervisor Xen. A su vez, las aplicaciones mencionadas son accesibles dentro de un mismo escritorio y se destacan visualmente con diferentes colores de borde de ventana. Cada entorno tiene acceso de lectura al sistema de archivos ra\u00edz base y al almacenamiento local, que no se cruza con los almacenamiento de otros entornos, y para organizar la interacci\u00f3n de las aplicaciones se utiliza un servicio especial.       <\/p>\n<p>Como base para la formaci\u00f3n de entornos virtuales, se puede utilizar la base de paquetes de Fedora y Debian; tambi\u00e9n se mantienen por la comunidad plantillas para Ubuntu, Gentoo y Arch Linux. Es posible organizar el acceso a aplicaciones en una m\u00e1quina virtual con Windows, as\u00ed como crear <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/vps\/\"   title=\"m\u00e1quinas virtuales\" data-wpil-keyword-link=\"linked\">m\u00e1quinas virtuales<\/a> una basada en Whonix para proporcionar acceso an\u00f3nimo a trav\u00e9s de Tor. La interfaz de usuario est\u00e1 construida sobre Xfce. Cuando el usuario inicia una aplicaci\u00f3n desde el men\u00fa, esta aplicaci\u00f3n se ejecuta en una m\u00e1quina virtual espec\u00edfica. El contenido de los entornos virtuales se define por un conjunto de plantillas.     <\/p>\n<p>En la nueva versi\u00f3n, la plantilla para entornos virtuales se ha actualizado a Fedora 44. El paquete del n\u00facleo de Linux se ha actualizado a la versi\u00f3n 7.2. Se han corregido errores y vulnerabilidades acumuladas, incluidas vulnerabilidades cr\u00edticas en el hipervisor Xen y una vulnerabilidad cr\u00edtica en la utilidad \u00abqvm-copy-to-vm\u00bb, que permit\u00eda eludir la separaci\u00f3n y ejecutar c\u00f3digo en el nivel Dom0.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
