Hello. I'm trying to configure Debian 12 / DomU on my (Arm32) Chromebook because I want to use the Internet and I want its IP address to be seen from "outside" of my LAN.
This is the tutorial that I'm following : https://github.com/mobile-virt/u-boot-chromebook-xe303c12/tree/chromebook/xen#starting-a-domu-guest Given these config files : A) on the host os (Devuan 5) Linux devuan-bunsen 6.1.61-stb-xen-cbe+ #1 SMP PREEMPT Sat Nov 4 13:46:17 EDT 2023 armv7l root@devuan-bunsen:~# ifconfig lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 2729 bytes 8279984 (7.8 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 2729 bytes 8279984 (7.8 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 mlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.7 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::8839:239b:9b37:cf84 prefixlen 64 scopeid 0x20<link> RX packets 19694 bytes 2193230 (2.0 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 18757 bytes 10464406 (9.9 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 vif4.0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.7 netmask 255.255.255.255 broadcast 192.168.1.255 ether fe:ff:ff:ff:ff:ff txqueuelen 1000 (Ethernet) RX packets 359 bytes 94924 (92.6 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 42 bytes 1764 (1.7 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 nano debian.cfg : kernel = '/Dati/xen/kernels/zImage-6.1.61-stb-xen-cbe+' memory = '768' name = 'Debian-bookworm' vcpus = '1' disk = [ '/Dati/xen/debian.img,,xvda,w' ] vif = [ 'type=vif,mac=00:16:3e:12:34:56,script=vif-route' ] extra = 'console=hvc0 root=/dev/xvda rw init=/sbin/init xen-fbfront.video=24,1024,768' nano /etc/xen/scripts/vif-route-local : #!/bin/bash #============================================================================ # ${XEN_SCRIPT_DIR}/vif-route # # Script for configuring a vif in routed mode. # # Usage: # vif-route (add|remove|online|offline) # # Environment vars: # dev vif interface name (required). # XENBUS_PATH path to this device's details in the XenStore (required). # # Read from the store: # ip list of IP networks for the vif, space-separated (default given in # this script). #============================================================================ dir=$(dirname "$0") .
