Hello to everyone.
I'm trying to boot Linux 6.1.y as Xen dom0 on the Chromebook xe303c12, aka
Snow and configure and start a very basic domU guest,following the Chuck's
tutorial,located here :
https://github.com/mobile-virt/u-boot-chromebook-xe303c12/tree/chromebook/xen#starting-a-domu-guest
What I did has been to carefully follow his instructions,but I haven't
found a solution to fix this problem,yet :
# sudo xl create devuan.cfg -c
Parsing config from devuan.cfg libxl:
error: libxl_create.c:720:libxl__domain_make: domain creation fail:
Permission denied
libxl: error: libxl_create.c:1309:initiate_domain_create: cannot make domain: -3
This is my devuan.cfg file :
kernel = '/Dati/xen/kernels/zImage-6.1.59-stb-xen-cbe+'
memory = '512'
name = 'Devuan'
vcpus = '1'
disk = [ '/Dati/xen/devuan.img,,xvda,w' ]
extra = 'console=hvc0 root=/dev/xvda rw init=/sbin/init
xen-fbfront.video=24,1024,768'
(I have tried also with root=/dev/xvda1 and root=/dev/xvda2,but leaving
disk = [ '/Dati/xen/devuan.img,,xvda,w' ] and not xvda1 or 2)
I have no idea about the reason(s) I always get that error,but I don't
think it is caused by a wrong creation of the devuan.img file. Can someone
point me in the right direction to understand what could be wrong ? I
haven't found any useful information on the internet.
This is bootxen.scr file where I have configured dom0_mem=768 :
mmc dev 1
ext2load mmc 1:3 0x42000000 zImage-6.6.0-xen-iommu-dma-on-xen
ext2load mmc 1:3 0x51000000 xen-4.17-armhf-armmp-0x51004000.ub
ext2load mmc 1:3 0x5ffec000 exynos5250-snow.dtb
fdt addr 0x5ffec000
fdt resize 1024
fdt set /chosen #address-cells <0x2>
fdt set /chosen #size-cells <0x2>
fdt set /chosen xen,xen-bootargs "console=dtuart dtuart=serial0

fdt mknod /chosen dom0
fdt set /chosen/dom0 compatible "xen,linux-zimage"

fdt set /chosen/dom0 reg <0x0 0x42000000 0x0 0x87C200 >
fdt set /chosen xen,dom0-bootargs "console=tty1 root=/dev/mmcblk1p4 rw
rootwait clk_ignore_unused --no-log"
bootm 0x51000000 - 0x5ffec000
and I've rebooted the Chromebook using this command :
SMDK5250 # mmc dev 1
SMDK5250 # ext2load mmc 1:3 0x50000000 bootxen.scr; source 0x50000000
This is the memory available on the machine after having booted the machine
ready for xen :
# free -m
total used free shared buff/cache available
Mem: 741 329 108 7 332 412
Swap: 0 0 0
I've found a similar error on this post,made on 2012 :

and according to what has been asked there,I want to post some further
relevant informations to help you to help me to debug the problem :
