I think I found the solution here :

https://blog.roberthallam.org/2020/05/solving-unable-to-find-partition-containing-kernel/

I've created a file called menu.lst inside the boot directory of the image file called "debian.img",adding the following content inside :

default 0
timeout 10
title Debian
root (hd0,1)
kernel /boot/vmlinux-6.1.59-stb-xen-cbe+ root=/dev/xvda
initrd /boot/initrd.img-6.1.59-stb-xen-cbe+

and I tried again to boot the image using virt-manager. It gave this error again :

root@devuan-bunsen:/mnt/zroot2/zroot2/OS/Chromebook/FreeBSD-guestOS/linux-xen/debian2/boot# 2023-11-29 15:21:09.266+0000: 2467: error : libxlDomainStartPerform:1256 : internal error: libxenlight failed to create new domain 'debian12'

but giving a look inside the log file and I found this interesting situation ;

Using <class 'grub.GrubConf.GrubConfigFile'> to parse /boot/grub/menu.lst

so,it seems that it tried to boot,but for an unknown reason,it gave the error anyway.

This tells you to look into the log file. Did you? What is there?

Is this the contents of that file? If so, then your xen installation is
broken because it did not install the .so.
