Can you at the very least share:

Thanks for your patience! I've attached a zip file with the info you
need. Additionally I've included the dmidecode of guest
(dmidecode_guest), host machine (dmidecode_host) and the domain info
of guest (libvirt.xml) in case they may be helpful. If you need further
info or any experiment I need to do, feel free to let me know! Now I
have access to the host machine so I can respond much faster.

Please check file boot_log_1st_kernel
