Hola Comunidad, necesito ayuda. Estoy creando una máquina virtual 100% headless, pero al momento de ejecutar, se detiene y me muestra el instalador en modo texto.
Please use English when interacting with the libvirt community, as there's no guarantee that other people will be able to understand your native language.

Looking at /var/log/syslog in the installer environment: preseed: successfully loaded preseed file from file:///preseed.cfg reopen-console: Found /preseed.cfg; falling back to simple mode for preseeding reopen-console: Found "auto" in the command line; falling back to simple mode for preseeding reopen-console: Running with preseeding. Picking preferred ttyS0 ONLY main-menu[1670]: INFO: Menu item 'file-preseed' selected preseed: successfully loaded preseed file from file:///preseed.cfg ... main-menu[1670]: INFO: Menu item 'localechooser' selected localechooser: info: debian-installer/language preseeded to 'es' (seen: true) localechooser: info: debian-installer/country preseeded to 'CO' (seen: true) localechooser: info: debian-installer/locale preseeded to 'es_CO.UTF-8' (seen: true) localechooser: info: Preseeded language ignored: unknown language code So I'm guessing this is the line it doesn't like: d-i localechooser/supported-locales multiselect es_CO.UTF-8 Anyway the OS installer is clearly picking up your configuration, so the problem is not in libvirt or the virtualization stack. You'll just have to figure out how to fix your preseed file :) Best of luck! -- Andrea Bolognani / Red Hat / Virtualization
